List of file types used by various applications from Microsoft Office productivity suite and Office 365 apps.

This category of file extensions contains file types from the Microsoft Office productivity suite and its individual programs. The latest edition, Office 2016, is available for Windows and OS X in several editions that offer various combinations of productivity software and also as a subscription based platform - Office 365. The latest editions of Office offers the following programs:

  • Word (all editions)
  • Excel (all editions)
  • PowerPoint (all editions)
  • OneNote (all editions)
  • Outlook (Home and Business and higher)
  • Publisher (Professional and higher; Windows only)
  • Access (Professional and higher; Windows only)
  • Skype for Business (Professional Plus and higher; Windows only)
  • Additionally, there are two programs from the Office suite that are not part of any of the suites at this time, namely Visio and Project. These two can be only obtained as part of Office 365 subscription.

Over the years, users became familiar with most of the common Microsoft Office file extensions, with .doc, .xls, and .ppt files being probably the three most known. With the release of Office 2007, Microsoft was trying to leave those well-known extensions in the past and replace them with the new XML-based formats that have a 4-letter file extensions, with "x" being appended to the original extension, so for example .doc became .docx, .xls -> .xlsx, .ppt -> .pptx etc. The key difference is that the original files were saved in binary form and the new ones are XML-based. These new formats are still being used in the latest 2016 edition of Microsoft Office, but the older formats are still supported and can be opened in their respective programs.

Another change introduced in the 2007 Office release was that there are different extensions for files that have macros enabled and those that do not. 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 to recognize documents that allow additional code (macro).
