Welcome to the Open XML Format SDK 1.0

This reference provides strongly-typed part classes to manipulate Open XML documents.

Welcome to the Open XML Format SDK 1.0. The 2007 Microsoft® Office system introduces a new file format that is based on XML called Open XML Formats. Microsoft Office Word 2007, Microsoft Office Excel® 2007, and Microsoft Office PowerPoint® 2007 all use these formats as the default file format. Open XML formats are useful for developers because they are an open standard and are based on well-known technologies: ZIP and XML. Microsoft provides a library for accessing these files as part of the WinFX technologies in the System.IO.Packaging namespace. This SDK is built on top of the System.IO.Packaging API and provides strongly-typed part classes to manipulate Open XML documents.
