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.

**What is Aspose.Cells? **

Aspose.Cells is a class library that allows your application to perform the following spreadsheet processing tasks: High Quality conversions between all popular Excel formats, including conversion to PDF, HTML, TIFF and printing.
