Microsoft Office file extension list

List of file name extensions of document and data types in the Microsoft Office suite releases.

This category of file extensions contains the most common and used files associated or used by Microsoft Office and applications, which are part of that suite, such as Microsoft Word, Microsoft Excel, Microsoft Access and others.

Over the years, users became familiar with most of the common Microsoft Office file extensions, with .doc, .xls, and .ppt being probably the three most known ones. With the release of Office 2007, Microsoft was trying to leave those well-known augmentations in the past and replace them with the new XML-based format that consists of 4-letter file extensions.

Since 2007, Microsoft Office documents are saved by using the new Office XML Formats, that have a new file name extensions that allow Office to differentiate these file format documents from binary documents used by previous Office versions. The new extensions borrow the old extensions from the existing binary files and add a letter to the end of the suffix. The default extensions for documents created in Word 2007, Excel 2007, and PowerPoint 2007 using the new file formats append the letter "x" and are .docx, .xlsx, and .pptx, respectively. Other Office document types that use the new file formats (including templates, add-ins, and PowerPoint shows) also received new extensions.

Another change introduced in the 2007 Office release is that there are different extensions for files that are macro-enabled versus those that are macro-free. Macro-enabled documents include a file name extension that ends with the letter "m" instead of an "x". For example, a macro-enabled Word 2007 document has the .docm extension, and thereby allows any user or software applications, to identify that it contains code, before the document is opened.

The file extensions introduced in Office 2007 are still being used by the latest Microsoft Office 2010 Editions, but the older three letter ones are still widespread, as a lot of older documents is still available in that file format.
