For all of you who cross the line into developer territory, the Open XML Format SDK is now available for download here. As you probably already know, Office 2007 introduces new file formats built on ZIP and XML technologies. The 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. The Open XML Format SDK is built on top of the System.IO.Packaging API and provides strongly-typed part classes to manipulate Open XML documents.
You can also find the SDK online at Welcome to the Open XML Format SDK 1.0.
