With the launch of office 2007 Microsoft has introduced a new format for office files. Microsoft office 2007 system use XML based file format. In office 2007 doc file is docx file and ppt and xls files are pptx and xlsx files respectively. These files are based on Office Open XML format. New file formats are zipped packages where settings, style, format and content is in xml format inside. The most important feature of this format is interoperability. Now any application that supports XML can work with the data in new file format. The development of office documents like power point presentation would be easier on the server side without any office component or software installation. You even don’t need to install office 2007 on a web server to create these documents.

Well, the thing is that We need to create a solution for our client where we need to generate the PPTs and XlSs files on the fly. We have decided to use this new file format for this task. As this is new thing around, so there is not much help available on the net. So I am much like eating the Microsoft's document on the subject.
