Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint

Exchanging files between previous releases of Office and Office 2007, Office 2010, or Office 2013

Microsoft added new file formats to Microsoft Word, Excel, and PowerPoint 2007, 2010, and 2013 to reduce file size, improve security and reliability, and enhance integration with external sources. To help ensure that you can exchange documents between Microsoft Office releases, Microsoft developed a Compatibility Pack for the Word, Office Excel, and Office PowerPoint file formats. This Compatibility Pack works with files created by Office 2013, Office 2010 and the 2007 Office systems.

The Open XML Formats usher in a new era of openness and transparency for Word, Excel and PowerPoint. Solution developers can take advantage of a host of new integration opportunities to connect documents to important sources of information. Learn more about the Open XML Formats.

Installing the Compatibility Pack

By installing the Compatibility Pack along-side of Microsoft Office XP, or Office 2003, you will be able to open, edit, save, and create files using the formats that are used by Office 2013, Office 2010 and the 2007 Office systems. Office 2000 users, as well as users of Windows 2000 SP4 and later, can convert Open XML Formats to binary file formats from within Windows Explorer.
