Getting Started with the Open XML SDK 2.0 for Microsoft Office
The Open XML SDK 2.0 for Microsoft Office simplifies the task of manipulating Open XML packages and the underlying Open XML schema elements within a package. The classes in the Open XML SDK 2.0 encapsulate many common tasks that developers perform on Open XML packages, so that you can perform complex operations with just a few lines of code.
Using the classes in the Open XML SDK 2.0 is simple. Once you have installed the Open XML SDK 2.0, open your existing project or application in Visual Studio, or create a new project or application. Then, in your project or application, add references to the following components.
