How to view images in pptx docx or xlsx files without office installed

Starting with the 2007 Microsoft Office system, Microsoft Office uses the XML-based file formats, such as .docx, .xlsx, and .pptx. These formats and file name extensions apply to Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. This article discusses key benefits of the format, describes the file name extensions and discusses how you can share Office files with people who are using earlier versions of Office.

In this article

What are the benefits of Open XML Formats?

The Open XML Formats include many benefits — not only for developers and the solutions that they build, but also for individual people and organizations of all sizes:

Compact files Files are automatically compressed and can be up to 75 percent smaller in some cases. The Open XML Format uses zip compression technology to store documents, offering potential cost savings as it reduces the disk space required to store files and decreases the bandwidth needed to send files via e-mail, over networks, and across the Internet. When you open a file, it is automatically unzipped. When you save a file, it is automatically zipped again. You do not have to install any special zip utilities to open and close files in Office.

Improved damaged-file recovery Files are structured in a modular fashion that keeps different data components in the file separate from each other. This allows files to be opened even if a component within the file (for example, a chart or table) is damaged or corrupted.

Support for advanced features Many of the advanced features of Microsoft 365 require the document to be stored in the Open XML format. Things like AutoSaveand the Accessibility Checker, for two examples, can only work on files that are stored in the modern Open XML format.

Better privacy and more control over personal information Documents can be shared confidentially, because personally identifiable information and business-sensitive information, such as author names, comments, tracked changes, and file paths can be easily identified and removed by using Document Inspector.

Better integration and interoperability of business data Using Open XML Formats as the data interoperability framework for the Office set of products means that documents, worksheets, presentations, and forms can be saved in an XML file format that is freely available for anyone to use and to license, royalty free. Office also supports customer-defined XML Schemas that enhance the existing Office document types. This means that customers can easily unlock information in existing systems and act upon it in familiar Office programs. Information that is created within Office can be easily used by other business applications. All you need to open and edit an Office file is a ZIP utility and an XML editor.

Easier detection of documents that contain macros Files that are saved by using the default “x” suffix (such as .docx, .xlsx, and .pptx) cannot contain Visual Basic for Applications (VBA) macros and XLM macros. Only files whose file name extension ends with an “m” (such as .docm, .xlsm, and .pptm) can contain macros.

Before you decide to save the file in a binary format, read Can different versions of Office share the same files?

How do I convert my file from the old binary format to the modern Open XML format?

With the file open in your Office app, click File > Save as (or Save a copy, if the file is stored on OneDrive or SharePoint) and make sure the Save as type is set to the modern format.

This will create a new copy of your file, in the Open XML format.

What are the XML file name extensions?

By default, documents, worksheets, and presentations that you create in Office are saved in XML format with file name extensions that add an “x” or an “m” to the file name extensions that you are already familiar with. The “x” signifies an XML file that has no macros, and the “m” signifies an XML file that does contain macros. For example, when you save a document in Word, the file now uses the .docx file name extension by default, instead of the .doc file name extension.

When you save a file as a template, you see the same kind of change. The template extension used in earlier versions is there, but it now has an “x” or an “m” on the end. If the file contains code or macros, you must save it by using the new macro-enabled XML file format, which adds an “m” for macro to the file extension.

The following tables list all the default file name extensions in Word, Excel, and PowerPoint.

Explorer on Windows10 does not recognise office apps

Hi, I have Microsoft office installed on my laptop (Office 2016) and I’ve had it for years. All was working well until today when I did a Windows update (I have been running Windows 10 since it came out). Suddenly I cannot double click on the office files to open them, for Excel and PowerPoint documents it asks me “How do you want to open this file?” and suggest I look for an app on Microsoft Store, but of course on Microsoft store it tells me that I already own the Excel App and have it installed. For Word documents it opens them in WordPad. Now the weirdest thing is that I have two user accounts on my laptop, when I am logged on my main user account there are no issues whatsoever but when I am logged on my second account that’s when I have problems! I have tried to do a repair on the app but it does not work – see the screenshot attached. I haven’t gone down the path of uninstalling and reinstalling since it works on my other account. Does anybody have a solution? ![80043-screenshot-excel-details.png][1] [1]: /answers/storage/attachments/80043-screenshot-excel-details.png

The Excel app shown on your image is not a traditional Excel application.
Please log on the Windows account with this issue, then go to Control Panel > Programs > Programs and Features , check whether there is Office 2016 displayed on Control Panel.

1. If yes, you may go back to Start menu > Settings > Apps > Excel (Or Word, PowerPoint) > Uninstall, just keep a traditional Office suite left like the following screenshot.
How to view images in pptx docx or xlsx files without office installed

If this step does not work, please go to File Explorer > Right click one Office file, such as one Excel workbook > Properties > Check whether the application is Excel.

You could click Change > More apps > Look for another app on this PC (The last option) > Locate to the root directory of the Office installation, choose EXCEL.EXE to open, click Apply, OK.
(For example, the 64-bit Office Professioanl Plus 2016, the path is C:\Program Files\Microsoft Office\Office16 .)
The 64-bit Office Home&Student 2016, the path is C:\Program Files\Microsoft Office\root\Office16 .)

The same step for other Office apps.

2. If not, the all Office apps seem to be installed from Microsoft Store. I would suggest you check the default app which used to open these files directly.
Click Default Apps on left button list > click “Choose default apps by file type” at bottom > make sure some Office files, such as the default app for .xlsx, .xls are Excel, for .docx, .doc are Word.

There are situations when you urgently need to see a presentation, but there is no access to PowerPoint. In this case, numerous online services will come to the rescue, which will allow you to run the show on any device, the main condition is the availability of Internet access.

Today we look at the most popular and easy-to-understand sites that allow you to view presentations online.

If the computer does not have PowerPoint or you need to start the presentation on mobile device, just go to the resources described below. All of them have a number of advantages and disadvantages, choose the one that will fully meet your needs.

Method 1: PPT Online

A simple and understandable resource for working with PPTX files (files created in older versions of PowerPoint with the .ppt extension are also supported). To work with the file, just upload it to the site. Please note that after downloading the file will be placed on the server and everyone will be able to access it. The service practically does not change the appearance of the presentation, but you can forget about the effects and beautiful transitions here.

You can only upload files up to 50 megabytes in size to the site, but in most cases this restriction is irrelevant.

On the site you can not only view files in PPTX format, but also find the desired presentation through a search engine. Now the service offers thousands of options from different users.

Method 2: Microsoft PowerPoint Online

Microsoft office applications can also be accessed online. To do this, it is enough to have a company account. The user can go through a simple registration, upload his file to the service and gain access not only to view, but also edit the document. The presentation itself is uploaded to the cloud storage, due to which access to it can be obtained from any device that has access to the network. Unlike the previous method, access to the downloaded file will be available only to you, or to people who will be given a link.

How to view images in pptx docx or xlsx files without office installed

In startup mode “Slide show” effects and transitions between slides are not displayed, text and placed pictures are not distorted and remain, as in the original.

Method 3: Google Presentations

The site allows not only to create presentations online, but also to edit and open files in PPTX format. The service automatically converts the files to a format that they understand. Work with the document is carried out on a cloud storage, it is advisable to register – so you can access files from any device.

Unlike the methods described above, Google Slides supports playback of animations and transition effects.

PPTX Presentation File Format

The PPTX format has become the standard format of PowerPoint 2007. Like its predecessor (PPT file), a PPTX file can contain slides with images, text, animation, audio, video, special effects, graphs, charts, etc. Unlike the binary PPT format, the new format uses Open XML, as well as ZIP compression. PowerPoint 2011 allows you to embed screenshots of your desktop or other programs directly into your presentation. It is also possible to edit and delete the background of images. However, despite the emergence of a new format, the program is criticized for its lack of effectiveness and ease of use.

Technical Details of PPTX Files

PPTX files use the ECMA-376 standard for Office Open XML. Any program that uses XML can access file information. PPTX files are created by zip-archiving the folder in which the information matches the OPC structure. The advantage of the PPTX format over PPT is that the first format makes it easier to work with files, manage file data, and restore data. It should be noted that PPTX files are not fully based on XML, since there are several binary sections contained in the files. Approximately 95% of the presentation software market is occupied by PowerPoint. Presentations PPTX and PPT may contain animation and special effects.

Additional PPTX Information

Hello! Unfortunately, not all users have encountered the docx, pptx, xlsx extension. And when it is necessary to edit documents of this format, the question actually arises: how to open docx, pptx or xlsx files? In this manual you can find out what these file extensions are and how they open.

If you have Microsoft Office 2000 or M-Office 2003 M-Office XP installed, then you most likely noticed that the format files are:
.doc – open in Microsoft World (text documents);
.xls – open in Microsoft Excel (spreadsheets);
.ppt – open in Microsoft PowerPoint (presentation).

Alternatively, if you’re working in .NET v4.5 or above, try using System.Web.MimeMapping.GetMimeMapping (yourFileName) to get MIME types. It is much better than hard-coding strings.

A working method in android to populates the mapping list mime types.

How to view images in pptx docx or xlsx files without office installed

This post will explore various approaches of fetching MIME Type across various programming languages with their CONS in one-line description as header. So, use them accordingly and the one which works for you.

For eg. the code below is especially helpful when user may supply either of .xls, .xlsx or .xlsm and you don’t want to write code testing extension and supplying MIME-type for each of them. Let the system do this job.

Using python-magic

Using built-in mimeypes module – Map filenames to MimeTypes modules

Operating System dependent

It will use FileTypeDetector implementations to probe the MIME type and invokes the probeContentType of each implementation to resolve the type. Hence, if the file is known to the implementations then the content type is returned. However, if that doesn’t happen, a system-default file type detector is invoked.

Resolve using first few characters of the input stream

Using built-in table of MIME types

It returns the matrix of MIME types used by all instances of URLConnection which then is used to resolve the input file type. However, this matrix of MIME types is very limited when it comes to URLConnection.

By default, the class uses content-types.properties file in JRE_HOME/lib. We can, however, extend it, by specifying a user-specific table using the content.types.user.table property:

Interpret the Magic Number fetched using FileReader API

Final result looks something like this when one use javaScript to fetch the MimeType based on filestream. Open the embedded jsFiddle to see and understand this approach.

Bonus: It’s accessible for most of the MIME Types and also you can add custom Mime Types in the getMimetype function. Also, it has FULL SUPPORT for MS Office Files Mime Types.

How to view images in pptx docx or xlsx files without office installed

The steps to calculate mime type for a file in this example would be:

  1. The user selects a file.
  2. Take the first 4 bytes of the file using the slice method.
  3. Create a new FileReader instance
  4. Use the FileReader to read the 4 bytes you sliced out as an array buffer.
  5. Since the array buffer is just a generic way to represent a binary buffer we need to create a TypedArray, in this case an Uint8Array.
  6. With a TypedArray at our hands we can retrieve every byte and transform it to hexadecimal (by using toString(16)).
  7. We now have a way to get the magic numbers from a file by reading the first four bytes. The final step is to map it to a real mime type.

      The OOXML specification is large and creating a friendly API to cover the entire specification is a very time consuming endeavor. This library attempts to provide an easy to use API for common use cases in creating OOXML documents while allowing users to fall back to raw document manipulation should the library’s API not cover a specific use case.

      The raw XML based types reside in the schema/ directory. These types are accessible from the wrapper types via a X() method that returns the raw type.

      For example, the library currently doesn’t have an API for setting a document background color. However it’s easy to do manually via editing the CT_Background element of the document.

      posted in apps, news, release by Jos Poortvliet

      With today’s release of the Office Online Integration app, enterprises can use a self-hosted Microsoft Office Online Server to view and edit documents from within Nextcloud. This enables companies to operate an Office environment on a private, secure server with a familiar user interface and full compatibility with Microsoft Office formats.

      How to view images in pptx docx or xlsx files without office installed

      About Office Online Server

      Office Online Server is an Office server product that provides browser-based file viewing and editing services for Office files. Office Online Server works with products and services that support WOPI, the Web app Open Platform Interface protocol.

      Office Online Server includes Word Online, Excel Online, PowerPoint Online and OneNote Online. Office Online Server runs on dedicated servers or a virtual machine, and thus fits in a on-premises environment with Nextcloud.

      Collaborative editing is supported, allowing multiple users to work together in the same document, seeing what the other users are doing.

      Integration

      From within Nextcloud, Office Online Server is well integrated like our other online office solutions, allowing users to directly view and edit documents without having to open other tabs or windows. Our sidebar is available so users can comment, share, see previous versions and even chat during editing. They can also drop a office document in a Talk chat room and edit it with the other participants during a call.

      Benefits

      The Office Online Server option allows enterprises to migrate users from cloud services or locally installed office applications to a web based work flow, fully on-premises and under control of the IT department. Users get the interface they are familiar with, and great document compatibility.

      Administrators can install the app and get started now.

      Notable Replies

      I suppose Nextcloud built this integration because the current Nextcloud services like Collabra and OnlyOffice apparently don’t meet the requirements of some in one way or the other.
      To use the integration it appears you will need a license. You can argue whether that is on-topic but at least very closely related and a basic requirement for the integration offered.

      I agree with many that this does not really agree with the Nextcloud philosophy on open source, however the MS Office Online Server should at least enable you to run it on-premises. Your warning regarding data collecting is appropriate as it is not clear what data will be exchanged or must be exchanged due to updates etc. with the Microsoft servers even when hosted on premises. There are ways to block that with firewalls, but the question is whether that would somehow cripple the product or even go against the license and support agreement.

      I’m running OnlyOffice on a separate server which I believe provides a good level of compatibility and speed with MS Office and is adequate for up to 20 users without further license costs. However their license/cost and support model might not work for everyone hence I welcome alternatives to cover more use cases including Collabra and MS Office Online Server.

      It sure enough doesn’t mean to encourage ppl to obtain a new licence for that product. And thus I think any discussion about getting yourself a new licence could be regarded as being OT.

      That was not my intention, just to clarify, inform and understand what existing OR new license and cost may be required to use this integration. We had similar and useful discussions about OnlyOffice and Collabra license models, but perhaps a separate thread is appropriate.

      This page covers how to edit files using the legacy Edit in Office method.

      Confluence provides two methods for editing files:

      • Edit files using the Atlassian Companion app
        Allows you to edit any type of file, if you have a compatible application installed. Requires you to install Companion on your computer.
      • Edit in Office using the Office Connector
        Allows you to edit Microsoft Excel, PowerPoint, and Word files with a compatible browser and Microsoft Office application. Provided for organizations who can’t use Companion.

      Your Confluence administrator will decide which method is best for your organisation.

      To check which method is available in your site, go to the file preview (click an image or file thumbnail). If you see the Edit button, your site is using the Companion app method, so the information on this page doesn’t apply to you.

      Editing Office files attached to a page

      The Office Connector allows you to edit Office files that are attached to pages, if your site does not use the Companion App method. You’ll need to use a browser, operating system and application (either Microsoft Office or OpenOffice) as described in the compatibility matrix below.

      To edit an Office document attached to a Confluence page:

      1. Go to > Attachments
      2. Choose Edit in Office beside the attachment you want edit.
        Your browser will ask you to confirm that you want to open the file.

      Choose OK.
      You may also see a security warning or be asked to log in to your Confluence server – enter your Confluence username and password, then choose OK.

      Edit in Office will not work on files that have special characters (such as ‘ # @ or €) in the filename.

      Edit options also appear in the:

        (choose Edit in Office beside each attached office file) and Office Excel macros – choose the Edit button above the content. macro – choose the edit icon on the viewer.

      Office Connector pre-requisites

      You can only edit files using the Office Connector if your system administrator has enabled this feature on your site. By default, Confluence requires you to install the Atlassian Companion app to edit attached files. See Edit Files

      Configuration matrix

      Edit in Office is only compatible with desktop applications. Online versions of Office applications are not supported.

      You need one of the following software combinations to edit Office files from your Confluence page.

      Microsoft Office 2010 SP2, 2013, 2016, 2019

      • Windows
      • Chrome
      • Firefox 1
      • Internet Explorer 11
      • Edge

      • Mac OS
      • Chrome
      • Firefox
      • Safari

      Microsoft Office XP, 2003, 2007, 2010 SP1

      The known supported Office editors for Linux are OpenOffice & LibreOffice, but in theory it should work with any WebDAV-aware application.

      If you experience problems editing documents using the Office Connector (using an application, operating system and browser combination above) contact our support team, who can raise an issue about it. Tell us as much as you can about your operating system, application version, document version (if it’s different to the version of Office / Open Office you’re using to open the document) and browser.

      Here are a few common issues:

      • Using Internet Explorer? You can only edit documents in Microsoft Office. OpenOffice is not supported.
      • Using Linux? You can only edit documents in OpenOffice. Microsoft Office is not supported.
      • Special characters in the filename? Edit in Office does not work for files with special characters (like ‘ # @ €) in the filename. See CONFSERVER-22403 – Getting issue details. STATUS
      • Not seeing the Office Connector options? Your system administrator needs to enable this feature, and can control how it appears on your site. See Enable Edit in Office as a dark feature and Configuring the Office Connector.

      Enable Edit in Office

      You need System Administrator global permission to do this.

      Go to > General Configuration > Office Connector.

      This will disable Companion app functionality for all users in the site.

      Troubleshooting

      Having problems with the Office Connector?

      • The WebDAV plugin must be enabled, because the Office Connector uses WebDAV to transfer information to and from Office documents. The WebDAV plugin is bundled with Confluence, and can be enabled or disabled by the System Administrator. If necessary, refer to the instructions on managing system and marketplace apps and configuring the WebDAV options.
      • Ensure that your Confluence server’s base URL is set correctly (see Configuring the Server Base URL to find out how to check this). When a user edits a Confluence page in Word and then uploads the page back to the Confluence server, the base URL determines where the document will be saved. If the base URL is incorrect, the documents may be saved to a different Confluence server.
      • Using Office 2013? Your administrator will need to enable ‘Allow authentication tokens in the URL path’ in the Office Connector configuration. See Configuring the Office Connector.

      See the Office Connector Limitations and Known Issues knowledge base article for more troubleshooting tips.

      Many organizations that rely on Google Apps also use Microsoft Office applications. Mass conversion of highly formatted documents, complex spreadsheets, or animated presentations may not always be practical. As a result, people still open and edit Word, Excel, and PowerPoint documents after a move to Google Apps.

      Microsoft Office files, however, no longer need to be stored on your local computer, server, or even on Microsoft’s OneDrive. Google Drive stores Microsoft Word, Excel, and PowerPoint files much like any file server. And Google encrypts the files when you upload them to Drive, and it stores the files in an encrypted state, too.

      Google also offers several ways to edit Microsoft Office files stored on Google Drive. Edit capabilities vary by operating system. Here’s a look at the options as of August 2015.

      Edit with Microsoft Office

      The most full-featured way to edit a Word, Excel, or PowerPoint file stored on Google Drive is with Microsoft Office, of course.

      People who use Office on Windows may open Office files from Google Drive with a plug-in. Simply install the Google Drive plug-in for Microsoft Office, and Google Drive will display as a file storage location in Word, Excel, and PowerPoint (Figure A). From within your Office app, open a file on Google Drive, make your changes, then save the file back to Google Drive.

      Figure A

      Open Microsoft Office files stored on Google Drive with a Google-created plug-in.

      You can also open an Office file stored on Google Drive from your Chrome browser–on either Windows or a Mac. First, install the Google Drive app for your system. Next, start Chrome and browse to your file on Google Drive (http://drive.google.com). Right-click (or, [Ctrl]+click) on a Word, Excel, or PowerPoint document, then choose “Open in…” and select the corresponding Office app (Figure B). When you’re done with your edits, the file saves to Google Drive.

      Figure B

      Right-click to open an Office file stored on Google Drive from your browser with an installed desktop app.

      On Android and iOS, use Google’s apps

      With Google’s mobile apps for Android or iOS, you can edit an Office document on the go. I suggest you install four apps:

      • Google Docs (Android, iOS) to edit Word documents
      • Google Sheets (Android, iOS) to edit Excel documents
      • Google Slides (Android, iOS) to edit PowerPoint documents
      • Google Drive (Android, iOS) to simplify file and folder management of all your documents

      You can create a new Word, Excel, or PowerPoint document with Google’s Android apps, but you must change a setting in each app to enable the feature (Figure C). While in the Google Docs Android app, touch the three-line menu (upper left), tap Settings, then check the box listed below the “Document Creation” section. Repeat the process for all three apps (Docs, Sheets, and Slides).

      Figure C

      On Android, change a setting to create a new Office format file on Google Drive from your mobile device.

      On iOS, you can’t create a new Word, Excel, or PowerPoint file with Google’s apps–you can only view, open, or edit. But there’s a work-around: “Make a copy” of an existing Office file (Figure D). For example, open the Google Docs app on your iPad/iPhone, choose a Microsoft Word file, then tap the three vertical dots in the upper right, tap “Share & export,” then click “Make a copy.” You’ll have a copy of your existing Word .docx format file, which you may then edit. Use the Google Drive iOS app to rename or move the file. The same process works for Excel files in Sheets and PowerPoint files in Slides. Just be sure to keep at least one Word, Excel, and/or PowerPoint format file on your Google Drive.

      Figure D

      On an iPhone or iPad, make a copy of an existing Office file within Google Docs, Sheets, or Slides. Then rename and/or move the file with the Google Drive iOS app.

      For basic edits on the web, use Chrome

      You may make basic edits to any Word, Excel, or PowerPoint document stored on Google Drive with Chrome on the web. Of course, you’ll have fewer edit options than with a native Google file. See the image to compare the Google web edit options for a standard Google Doc and Word file, a Google Sheet and Excel file, and a Google Slides and PowerPoint file (Figure E). In every case, the edit options are fewer.

      Figure E

      Compare Google’s web-based edit options for Word, Excel, and PowerPoint files to Google’s native formats.

      The bottom line: You have options

      In the early days, I encountered people who found it difficult to work with Office documents stored on Google Drive. Some colleagues of mine would try to open a Word file from within the Google Drive sync folder on their Windows desktop. Sometimes, they’d accidentally convert the file to a Google Doc. Then they’d download a copy of the file–in Word format again–and save it. They would end up with multiple files in various formats.

      Google’s desktop and mobile app compatibility with Microsoft Office files has improved. Now, you can open and edit your Office files stored on Google Drive in several ways. And, if you use a Mac or Windows system with Office installed, you can do so with the full editing power of Office.

      Does your organization use both Google Apps and Microsoft Office? If so, how do you handle existing Office format files? Share your experience in the discussion thread below.

      What file types can I edit from the Dropbox app with the mobile Office apps?

      On iOS the Edit icon in the Dropbox app will appear for the following file types:

      • .doc
      • .docx
      • .xls
      • .xlsx
      • .ppt
      • .pptx

      You can view and edit other Office file formats by opening them directly from the Office apps for mobile (Word, Excel, or PowerPoint). From the appropriate Office app, tap on the Account tab and connect your Dropbox if you haven’t already. Once connected, you can access the files in your Dropbox from the Open tab.

      On Android editing is available for the following file types:

      • .docx
      • .xlsx
      • .pptx

      Any other Office files will be read-only.

      Do I need to sign in with a Microsoft login in order to edit Office files?

      You can edit files stored in your personal Dropbox account (Basic, Plus, or Professional) without logging in with a Microsoft account (e.g. Hotmail, Outlook.com), however you’ll eventually be required to do so.

      A Microsoft login is also required when opening the Office apps directly to access your Dropbox files there.

      For Android tablets with screens larger than 10.1", an Office 365 subscription is also required to edit Office files stored in Dropbox Basic, Plus, and Professional accounts.

      How do I unlink or relink my Dropbox account from the Office Mobile apps?

      To unlink a Dropbox account from an Office Mobile app:

      1. Open the Office Mobile app.
      2. Tap the folder icon.
      3. From the list of places, tap and hold Dropbox.
      4. Once you’ve held your finger on Dropbox for a few seconds, a trash can icon will appear in the top right corner of the screen. Tap the trash can to remove Dropbox from the Office Mobile app.

      To re-link a Dropbox account to an Office Mobile app:

      1. Open the Office Mobile app.
      2. Tap the folder icon.
      3. Tap Add a place.
      4. Tap Dropbox.
      5. Tap Allow next to the Dropbox account listed (if you’re already signed in to the Dropbox app). Or, to link a new Dropbox account, tap Use a different account. You’ll be directed to a browser window where you can enter the credentials for the Dropbox account you’d like to connect.

      Do I need to pay for Office in order to edit my Office files?

      The Office apps are free to download onto your mobile device. Editing is free for Dropbox Basic, Plus, and Professional accounts.

      Dropbox Business accounts need an Office 365 account that includes Office client licensing (Business, Business Premium, ProPlus, E3, E4, or E5) in order to edit files with the mobile apps.

      Additionally, if you’re using a tablet larger than 10", Microsoft requires that you have an O365 license to use Office applications.

      Note: Business Essentials and E1 licenses are web-only and don’t include this feature on mobile.

      How do I edit Office files stored in the Dropbox mobile app?

      How do I set or clear an Office app as the default app for opening files?

      When you edit or open your Dropbox files with a third-party application, you have the choice to set that app as the default for opening files of that type. To set a default app to open certain file types:

      1. Tap on the file you’d like to open/edit to preview it.
      2. Once the document preview loads, tap the Edit icon (it looks like a pencil and paper).
      3. You will see a list of available third-party apps.
      4. Tap the app you’d like to use to open your file.
      5. You’ll have the option to use this app Always or Just once.
        • Choosing Always sets this app as the default app for opening this file-type from Dropbox.

      If you ever want to change or clear your default apps, you can do so from the Dropbox settings:

      1. Open the Dropbox app.
      2. Tap the menu button.
      3. Select Settings.
      4. Scroll down and tap Manage default apps.
      5. Find the app you’d like to remove and tap Remove.
      6. Confirm the removal by tapping Clear.

      Is offline editing supported?

      The Dropbox app allows you to make files available for offline use. Please follow the guidelines below if you’d like to edit your files while offline:

        Available offline

      How is this different from what I’ve already been able to do with third-party apps on Android?

      While the Dropbox app has supported editing files via third-party apps and saving them back to Dropbox for quite some time, this integration goes far deeper. We’ve streamlined the experience so that fewer steps are needed to edit and save your files. For the first time, you’ll be able to install Office through the Dropbox app. Office Mobile will also include ways to share links via Dropbox and open up the Dropbox app directly, making the experience more seamless than ever before.

      I’m not seeing the Microsoft Office integration—how do I get access?

      The Office apps are not currently available in all countries – once available, you’ll be able to utilize this integration. For those countries, we won’t show the Edit icon within the Dropbox app.

      Tapping the Edit icon while viewing an Office file in your Dropbox will show you an option to directly install the Office app. You can also go to the App Store (iOS) or Google Play Store (Android) to search for the Microsoft Office apps to install. You will not be able to download the apps, however, if your App Store or Google Play Store account is based in a country where the Office apps aren’t available.

      How do Save and Save As work on Office Mobile for Android?

      The Office Mobile app on Android provides the options to Save or Save As in the menu when viewing and editing documents.

      Using the Save option will replace the original file with your new edits.

      The Save As option is similar to using this feature on a computer—it will save a copy of the current file to your Dropbox. Please note that this saves the file in the home (or root) directory of your Dropbox; it will not save to the location of the original file and you won’t be able to select a subfolder within your Dropbox to save it to.

      You can use the Dropbox app, desktop client or website to move the newly edited copy anywhere in your Dropbox, including the original folder location. If the original file is still present, your new file will have a (1) appended to it.

      Please note that if the original file is stored in a shared folder, and you want the new file to be shared as well, you’ll need to to move the newly edited file into the shared folder, or simply use the Save option.

      LibreOffice is a successor to OpenOffice.org (commonly known as OpenOffice), which in turn was based on StarOffice. Many years of development have gone into the software, and it has been used in its various incarnations by millions. Today, LibreOffice is by far the most active continuation of the OpenOffice.org codebase, with releases every six months and hundreds of contributors. Also, LibreOffice uses libraries from the Document Liberation Project, handing control back to content creators.

      In order to view a file contained in a WinZip file, you need to have a program that is capable of displaying that type of file. WinZip can display text files using its built-in viewer and if you have a Pro registration will also open most picture files. For other types of files, though (including word processor documents), you will need to have an external program installed. The program you need depends on the type of file you want to display. For example, to display a Microsoft Excel spreadsheet (.xlsx), you must have either Excel or a viewer that is capable of displaying Microsoft Office documents.

      In many cases you will already have the software necessary to view files. For others, it is often possible to obtain free or inexpensive viewers. Some options for viewing a few of the most common file types are listed below.

      Note: By providing this list, WinZip Computing does not endorse any of the listed products or imply that they are superior to other similar products. Nor, of course, can we provide support for these programs. This list simply describes a few programs of which we are aware and is provided as a service to WinZip users.

      Many of the links below are to pages that are outside of the WinZip web site, they will open in new browser windows (or tabs), and may change without our knowledge.

          Graphics files (.jpg, .png, .gif, .bmp, etc.)

        WinZip will show thumbnails of your graphics files while in the default Tall Rows view or when in the Icon view. WinZip Pro also includes an internal image previewer that, when maximized, allows you to browse through full-size images without the need for a separate application and without manually extracting the images from the Zip file. The previewer also provides tools to rotate, resize, and delete images. This saves time and makes it easier than ever to manage images within your Zip files.

        If you don’t have the latest version of WinZip Pro, new WinZip users can buy a copy and registered users of an earlier version of WinZip can upgrade to the latest WinZip version for 50% off the full price, optionally choosing to upgrade to a Pro registration.

        Alternatively, you can use Window’s built-in Photo app to view graphics files.

        See the downloads page for more details.

        POI requires Java 8 or newer since version 4.0.1.

        4 March 2022 – CVE-2022-26336 – A carefully crafted TNEF file can cause an out of memory exception in Apache POI poi-scratchpad versions prior to 5.2.0

        Description:
        A shortcoming in the HMEF package of poi-scratchpad (Apache POI) allows an attacker to cause an Out of Memory exception. This package is used to read TNEF files (Microsoft Outlook and Microsoft Exchange Server). If an application uses poi-scratchpad to parse TNEF files and the application allows untrusted users to supply them, then a carefully crafted file can cause an Out of Memory exception.

        Mitigation:
        Affected users are advised to update to poi-scratchpad 5.2.1 or above which fixes this vulnerability. It is recommended that you use the same versions of all POI jars.

        10+16+18 December 2021- Log4j vulnerabilities CVE-2021-44228, CVE-2021-45046 and CVE-2021-45105

        The Apache POI PMC has evaluated the security vulnerabilities reported for Apache Log4j.

        POI 5.1.0 and XMLBeans 5.0.2 only have dependencies on log4j-api 2.14.1. The security vulnerabilities are not in log4j-api – they are in log4j-core.

        If any POI or XMLBeans user uses log4j-core to control their logging of their application, we strongly recommend that they upgrade all their log4j dependencies to the latest version (currently v2.17.1) – including log4j-api.

        13 January 2021 – CVE-2021-23926 – XML External Entity (XXE) Processing in Apache XMLBeans versions prior to 3.0.0

        Description:
        When parsing XML files using XMLBeans 2.6.0 or below, the underlying parser created by XMLBeans could be susceptible to XML External Entity (XXE) attacks.

        This issue was fixed a few years ago but on review, we decided we should have a CVE to raise awareness of the issue.

        Mitigation:
        Affected users are advised to update to Apache XMLBeans 3.0.0 or above which fixes this vulnerability. XMLBeans 4.0.0 or above is preferable.

        20 October 2019 – CVE-2019-12415 – XML External Entity (XXE) Processing in Apache POI versions prior to 4.1.1

        Description:
        When using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents, a specially crafted document can allow an attacker to read files from the local filesystem or from internal network resources via XML External Entity (XXE) Processing.

        Mitigation:
        Apache POI 4.1.0 and before: users who do not use the tool XSSFExportToXml are not affected. Affected users are advised to update to Apache POI 4.1.1 which fixes this vulnerability.

        26 March 2019 – XMLBeans 3.1.0 available

        The Apache POI team is pleased to announce the release of XMLBeans 3.1.0. Featured are a handful of bug fixes.

        The Apache POI project has unretired the XMLBeans codebase and is maintaining it as a sub-project, due to its importance in the poi-ooxml codebase.

        A summary of changes is available in the Release Notes. People interested should also follow the POI dev list to track progress.

        The XMLBeans JIRA project has been reopened and feel free to open issues.

        POI 4.1.0 uses XMLBeans 3.1.0.

        XMLBeans requires Java 6 or newer since version 3.0.2.

        11 January 2019 – Initial support for JDK 11

        We did some work to verify that compilation with Java 11 is working and that all unit-tests pass.

        See the details in the FAQ entry.

        Mission Statement

        The Apache POI Project’s mission is to create and maintain Java APIs for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft’s OLE 2 Compound Document format (OLE2). In short, you can read and write MS Excel files using Java. In addition, you can read and write MS Word and MS PowerPoint files using Java. Apache POI is your Java Excel solution (for Excel 97-2008). We have a complete API for porting other OOXML and OLE2 formats and welcome others to participate.

        OLE2 files include most Microsoft Office files such as XLS, DOC, and PPT as well as MFC serialization API based file formats. The project provides APIs for the OLE2 Filesystem (POIFS) and OLE2 Document Properties (HPSF).

        Office OpenXML Format is the new standards based XML file format found in Microsoft Office 2007 and 2008. This includes XLSX, DOCX and PPTX. The project provides a low level API to support the Open Packaging Conventions using openxml4j.

        For each MS Office application there exists a component module that attempts to provide a common high level Java api to both OLE2 and OOXML document formats. This is most developed for Excel workbooks (SS=HSSF+XSSF). Work is progressing for Word documents (WP=HWPF+XWPF) and PowerPoint presentations (SL=HSLF+XSLF).

        The project has some support for Outlook (HSMF). Microsoft opened the specifications to this format in October 2007. We would welcome contributions.

        As a general policy we collaborate as much as possible with other projects to provide this functionality. Examples include: Cocoon for which there are serializers for HSSF; Open Office.org with whom we collaborate in documenting the XLS format; and Tika / Lucene, for which we provide format interpretors. When practical, we donate components directly to those projects for POI-enabling them.

        Why should I use Apache POI?

        A major use of the Apache POI api is for Text Extraction applications such as web spiders, index builders, and content management systems.

        So why should you use POIFS, HSSF or XSSF?

        You’d use POIFS if you had a document written in OLE 2 Compound Document Format, probably written using MFC, that you needed to read in Java. Alternatively, you’d use POIFS to write OLE 2 Compound Document Format if you needed to inter-operate with software running on the Windows platform. We are not just bragging when we say that POIFS is the most complete and correct implementation of this file format to date!

        You’d use HSSF if you needed to read or write an Excel file using Java (XLS). You’d use XSSF if you need to read or write an OOXML Excel file using Java (XLSX). The combined SS interface allows you to easily read and write all kinds of Excel files (XLS and XLSX) using Java. Additionally there is a specialized SXSSF implementation which allows to write very large Excel (XLSX) files in a memory optimized way.

        Components

        The Apache POI Project provides several component modules some of which may not be of interest to you. Use the information on our Components page to determine which jar files to include in your classpath.

        We may come across the need to extract images or text from an MS Word or MS Powerpoint file. Usually, this may include manual copying and pasting, one page at a time, and with mega-large files, this is going to take quite a bit of time.

        Well, we have a simple trick to help you extract images and text from files of the new format ie DOCX, PPTX, XLSX whereas with files of the older format ie DOC, PPT, XLS, all you need is a free software to help you quickly and easily extract images.

        Note: For the purpose of demonstrating this post, we will be using only an MS Word file. The process is the same for MS Powerpoint and MS Excel files.

        Here’s what this article covers:

        1. How to extract images & text from DOCX, PPTX, XLXS files
        2. How to extract images from a single DOC, PPT or XLS file
        3. How to extract images from multiple DOC, PPT or XLS files
        4. How to extract images with “Save as Web Page” method
        5. How to extract plain text instead of XML

        How to Extract Images & Text from DOCX, PPTX, XLXS Files

        Before following the steps, open the folder containing your files. click Organize > Folder and Search Options > View and uncheck Hide extensions for known file types. Now, you can see the file extension with each filename.

        Locate and select the file you want to extract images and text from (note: it is better to make a copy of said file). In this example, our target file is named Sample File.docx.

        Press F2 to rename the file and replace the extension name with .zip.

        A warning will be shown to confirm the change of the file extension. Click Yes.

        Right click on the ZIP file and click on Extract files.

        Locate and open the folder containing the extracted data and then open the word.

        In it you will see a few folders and XML files. In the media folder you will find the extracted images. For the exracted text, open the document.xml file with notepad or XML Notepad.

        Here’s what you will find in the media folder.

        How to view images in pptx docx or xlsx files without office installed

        How to Extract Images from a Single DOC, PPT or XLS File

        If you want to extract images from MS office files with older formats, the above method won’t work with the images. You need a free tool called Office Image Extraction Wizard for this purpose. The tool works with MS Office files as far back as 2012 and it works with one or multiple MS Office files in one go.

        Download and install Office Image Extraction Wizard.

        Choose the document you want to extract images from (for this example, we’re doing it to a folder I named Ch1.doc), and select the output folder. You can opt to have a folder created to house all your output images by ticking the option Create a folder here. Once you are done, click Next.

        Click Start to begin the process.

        Once the image extraction process is finished, click on Click here to open destination folder and it will open the output folder.

        As you can see below, the program has created a Ch1 folder.

        Inside the folder are the extracted images.

        How to Extract Images from Multiple DOC, PPT or XLS Files

        For extracting images from multiple files of the DOC, PPT or XLS formats, tick the Batch mode option found at the bottom left.

        Click on Add Files and then select the files you want to extract images from. Hold the Ctrl button to select multiple files in one go. After selecting the files, click Next.

        Click Start.

        When the process is completed, locate and open the output folder. Here, you will see two folders with the original filenames. Open these folders to see the extracted images from their original MS Office files.

        How to Extract Images with “Save as Web Page” Method

        There is another method that will work with both newer and older MS Office files.

        Open the DOCX or XLSX file and click on File > Save As > Computer > Browser and save file as Web Page.

        Locate the folder with the filename you saved the Web Page in. Here, you will see all the images extracted from the file.

        How to Extract Plaintext Instead of XML

        Open the DOCX file and click on File > Save As > Computer > Browser. Choose to save file as Plain Text (for XLSX files, save it as Text (Tab delimited)).

        Locate and open the text file with the name you have used to save it. This text file will contain only the text from your original file without any formatting.

        If you know any other method or tool to extract images from MS Office files, please mention in the comments section.

        This article explains what XLSX files are, how to open them, and which programs are able to convert them to other spreadsheet formats like CSV or ODS.

        What Is an XLSX File?

        A file with the XLSX file extension is a Microsoft Excel Open XML Format Spreadsheet file. It's a ZIP-compressed, XML-based spreadsheet file created by Microsoft Excel version 2007 and later.

        XLSX files organize data in cells that are stored in worksheets, which are in turn stored in workbooks (files that contain multiple worksheets). The cells of a spreadsheet are positioned by rows and columns and can contain styles, formatting, math functions, and more.

        Spreadsheet files made in earlier versions of Excel are saved in the XLS format. Excel files that support macros are XLSM files.

        Lifewire / Chloe Giroux

        How to Open an XLSX File

        Unless you've purposely installed a program to your computer that can open XLSX files, then double-clicking on one won't do anything useful. Instead, you need to have a specific program on your computer that can recognize the XLSX file.

        Although Microsoft Excel (version 2007 and newer) is the primary software program used to both open XLSX files and edit XLSX files, you can install the Microsoft Office Compatibility Pack to open, edit, and save XLSX files using an older version of Excel.

        If you have no intention to edit the XLSX file, and you just want to view it, you can install the free Microsoft Office Excel Viewer. It supports printing and copying data out of the XLSX file, too, which might be all you need to do.

        You can also open and edit XLSX files without Excel, completely free, using WPS Office Spreadsheets, OpenOffice Calc, or LibreOffice Calc. If you’re on a Mac, Apple Numbers supports XLSX files, too (but not all features will work).

        Google Sheets, Microsoft Excel Online, and Zoho Docs are a few other ways you can open and edit XLSX files for free. Going this route requires you to upload the XLSX file to the website before you can make any changes.

        If you use the Chrome web browser, you can install Office Editing for Docs, Sheets & Slides as an extension, which lets you open and edit XLSX files directly in the browser, either by dragging a local XLSX file into Chrome or opening one from the internet without having to download it first.

        Installing Chrome extensions is pretty straightforward, but if you need some step-by-step help, we have a guide on how to add extensions to Chrome.

        How to Convert an XLSX File

        If you have one of the applications we've already mentioned installed on your computer, it's recommended to use that same program to save whatever XLSX you're working with to the specific format you're interested in. This is normally done through the File > Save as menu option.

        For example, if you're using Excel, go through its FILE > Save As > Browse menu and choose CSV, XLS, TXT, XML, etc. The F12 key should also work to get to the Save As window.

        Sometimes the quickest solution to convert an XLSX file isn’t with a tool you have installed, but instead via a free file conversion software program or online service like Zamzar or Convert Files.

        Just looking at the capabilities of those two services, you can convert whatever Excel file you have to many different file types, like XLSX to CSV, XML, DOC, PDF, ODS, RTF, XLS, MDB, and even image and web file formats like JPG, PNG, and HTML.

        Still Can't Open the File?

        The most likely reason for why the file won't open at this point, if you've tried all the suggestions above, is that you're not really dealing with an XLSX file. This might happen if you've only briefly looked at the file extension and are confusing it for an Excel file.

        For example, maybe your file really ends in .LSX, in which case it's a Streaming Media Shortcut file and has nothing to do with Excel. Windows Media Player opens LSX files.

        Similarly, it’d be easy to confuse an SLX file for one that has the Excel XLSX suffix, but SLX files are also unrelated to Excel and are instead used by programs like Simulink and SpectraLayers.

        XLR is another one that’s easy to mix up for an Excel file.

        If you can't open the file, re-read the extension and research it online. It should be fairly easy to find more information about the format and learn which programs are able to open and convert it. We may even have a description of it here on Lifewire—use the search box at the top of this page to check.

        To read an XLSX file in R, first copy the data from Excel, then import data from the clipboard into R.

        You can read the file with the Python module named openpyxl. Download the openpyxl module, then use the Python import command to read the data from the XLSX file.

        If you have a PowerPoint file and you are unable to hear the audio portion of the document, then here are some things to look at that might help. Please note that these instructions where created with PowerPoint 2010 on a PC running Windows version 7 in mind. Some of the procedures may not work with your version of PowerPoint or Windows.

        Have you tried it on another computer?

        Before you do any trouble-shooting, it might be best to check if the presentation runs on another computer. If it runs on another computer then atleast you know it must simply be a setting on your computer. If the audio in the presentation does not play on another computer either then it is possible that the presentation is broken in some way. Reply to the sender and ask them if others have reported an issue with the presentation.

        A few things to note

        • If you are trying to play the presentation on a work computer, then try to run it on a home computer. Some work computers can be locked down that may prevent PowerPoint presentations from running properly.
        • A common mistake someone can make when adding sound to the presentation is to link the file, instead of embedding the file. If the file is linked, then the receiver of the file must have access to the original location of the linked file. So if the file is "linked" to the originator’s computer c: drive, the receiver cannot play the sound file, because he/she has no access to the originator’s c: drive.

        Once you are sure the issue is not with the file, you are ready to trouble-shoot your issue

        Reboot your computer

        "Have you tried turning it off and on again" is a common catch phrase amongst "techies" but the reality is that sometimes a simple reboot of your computer is all you needed to do to fix most problems.

        Check your system volume

        • On the taskbar, right-click or double click on the speaker icon beside the time (Bottom right) and open the sound "mixer".
        • Make sure all the volumes are set at a proper lever, and that nothing is muted.
        • Also, play something else with sound to make sure that your speaker are connected and working. (CNN videos is a great test)

        Make sure you have started the presentation

        When you receive a presentation from someone, sometimes it is not in the "show" format so you need to start the presentation by clicking on the little "slide show" button. Otherwise you are in the edit mode and clicking/double-clicking on the Audio icon will not play the sound until you are actually watching the presentation.

        Check the slide show volume in PowerPoint

        • Open the presentation file, but don’t start the show yet.
        • On the Options tab, check to make sure the "slide show volume" is not set to Mute.

        Can you play the sound when editing the presentation?

        • Open the presentation file, but don’t start the show yet.
        • Right-click on the audio icon in the presentation and select Preview. Can you hear it?

        Check your PowerPoint Volume in the System Mixer

        • Open the presentation file and press F5 or the "slide show" button to start the presentation
        • While the presentation is playing, press Ctrl + T to show the taskbar
        • Right-click or double click on the speaker icon beside the time (Bottom right) and open the sound "mixer".
        • You should see a volume level associated with the PowerPoint app. Make sure the volume is up and not muted.

        Replace/Repair/Update Windows Media Player

        Most websites will say PowerPoint sound issues are related to a problem with the Windows Media Player (the default player that is provided free with all Microsoft operating systems). To fix these issues you have three main choices: Upgrade your Windows Media Player, Update your Windows Media Player or Repair your Windows Media Player. You only need to do one of these options, not all three

        Upgrade your Windows Media Player

        • Visit this page for the latest version of the Windows Media Player
          • Follow the instructions to “download the player”.
          • If, during the process, the installation asks you, or mentions, that your device is not the primary source for all media types, please select yes, to have to take over that control.
          • When you are done, try your presentation again.

          Update your Windows Media Player

          • Visit this page for instructions on how to update your Windows Media Player.
          • Visit this page to download the latest codecs for your Windows Media player

          Repair your Windows Media Player by Restoring the Windows Defaults

          • Close PowerPoint if it is still open
          • Click on the Windows button (bottom left) and select Default Programs
          • Click on Default Programs and wait for the list to load. (This can take a minute or two)
          • Click on Windows Media Player and see what it says about defaults. If it says “This program has all it’s defaults” then this is not the issue. If it says anything else, click on the Set this program as default
          • Answer whatever questions it asks and choose the default option each time.
          • Try running the presentation again

          Run Office Repair Tool

          • Make sure all Office products including PowerPoint, Word and Outlook is closed.
          • Go into Control Panel and choose “ Program and Features ” (If you see only 8 icons, you need to change the view from “Category” to “small icons”
          • Select Microsoft Office Professional 20## and click Change

          • When it is done, close the window and try running the presentation again

          OpenTBS is a plug-in for the TinyButStrong Template Engine.

          TinyButStrong is a PHP Template Engine which has special template syntax and allows you to design templates in their natural editing tools. But it normally works only for Text files, including XML and HTML.

          With TinyButStrong and its plug-in OpenTBS, you can use the template engine to merge OpenOffice documents and Ms Office documents with lot of facilities. All OpenDocument Format (ODF) and Office Open XML (OOXML) can be merged with OpenTBS, and also XPS files (XPS is a PDF competitor provided by Microsoft). In fact, all zip archives containing Xml/Html/Text files can be merged with OpenTBS.

          Since version 1.10.0, OpenTBS can also read data in workbooks (xlsx and ods files).

          What is special to OpenTBS:
          • Design your templates directly with OpenOffice or MS Office.
          • No exe file needed to merge documents.
          • No temporary files needed to merge documents.
          • Output directly as an http download, a new file on the disk, or as a string (for file attachment for example).
          • Works with PHP 8, PHP 7 and PHP 5.
          • No PHP extension is required (If the Zlib extension is enabled it becomes easier to use templates, see more detail below)

          You should know Template Engines and more specifically TinyButStrong to use OpenTBS.

          2. Installing

          Requirements:
          • TinyButStrong version 3.12.0 or higher.
          • PHP 8, PHP 7 or PHP 5.
          • It is better to have the Zlib extension enabled on your PHP installation. If it’s not, here is what to do.
          Installation:

          Just put the file "tbs_plugin_opentbs.php" with your PHP scripts.

          3. Understanding principles

          It is important to figure out that documents made with LibreOffice, OpenOffice and Ms Office (since version 2007) are technically zip archives containing XML files, even if the extension of the document is not ".zip". Those zip archives can contain other file types like pictures or sounds, but the document structure and the text contents are saved as XML files. The XML Synopsis summarizes the key entities of XML sub-files contained in LibreOffice, OpenOffice and Ms Office documents.

          TinyButStrong can merge XML files, but cannot read zip archives by itself. The plug-in OpenTBS extends the TinyButStrong methods LoadTemplate() and Show() to make them working with zip archives. But you do not have to bother with it because OpenTBS is managing archives in a way that is quite invisible for you.

          When the OpenTBS plugin is installed, the LoadTemplate() method becomes able to first load a zip archive (a LibreOffice, OpenOffice or Ms Office document), and then to load the contents of any XML or Text files stored in the archive. Then you can load an merge the contents of XML or Text files with all features of the TinyButStrong template engine. TBS can merge fields and blocks only for the current loaded sub-file, but OpenTBS make you very easy to manage sub-files and gives lot of facilities for special contents such as pictures, charts, . . At the end, the Show() method does render the entire zip archive including modified stored files. The render can be done as an HTTP download, or a new file on the server’s disk, or as a PHP string containg the binary of the result archive.

          Since OpenTBS version 1.3, you can also add and delete files in the archive.

          OpenTBS has automatic extension recognition. When you load a document which has one of the following extensions < odt, odg, ods, odf, odp, odm, docx, xlsx, pptx >, then the main XML file of the archive are automatically loaded, and some special character conversion are preset. For example, for all OpenDocument files, the stored file "content.xml" is automatically loaded.

          Since version 1.6.0, if the extension is not recognized then OpenTBS also try to find the document by the sub-file presence. And if all fails, then you can force the document type using a special command.
