The Open XML Formats are the new default file formats for Word, Excel and PowerPoint (docx, xlsx, pptx). With the Open XML SDK, which provides a set of .NET APIs that allows developers to create and manipulate documents in the Open XML Formats, and the Office services available on SharePoint 2010 (Word Automation Services, which performs high-performance bulk document conversions, and Excel Services, which provides server-side support for spreadsheet calculation), developers can now build solutions for server environments without the need of the Office clients. With just a few lines of code you will be able to create rich solutions, like document assembly.
