Why Not Open XML SDK

What is Open XML SDK?

According to the MSDN Library, Open XML SDK is defined as:

The Open XML SDK 2.0 simplifies the task of manipulating Open XML packages and the underlying Open XML schema elements within a package. The Open XML SDK 2.0 encapsulates many common tasks that developers perform on Open

XML packages, so that you can perform complex operations with just a few lines of code.

OOXML documents are essentially zipped XML files and Open XML SDK is a collection of classes that allows you to work with the content of OOXML documents in a strongly-typed way. That is instead of unzipping a file to

extract XML, loading that XML into a DOM tree and working with XML elements and attributes directly, Open XML SDK provides classes to do that.
