The Open XML Format SDK Technology Preview simplifies the task of manipulating Open XML packages. The Open XML Application Programming Interface (API) encapsulates many common tasks that developers perform on Open XML packages, so you can perform complex operations with just a few lines of code. Using this API, you can programmatically generate and manipulate Word 2007 documents, Excel 2007 spreadsheets, and PowerPoint 2007 presentations. The programming model uses managed code, so it's safe for server-side scenarios.
