Do you want to modify the excell file in your code or launch Excell?

 

I don't know about the old xls files, but the new *.xlsx files are actually zip archives (you can test this by renaming the file). You need to first extract the contents. After that all contents are in xml files.

I'm not sure you can do this with web app since I normally use winforms, but try looking at the Excel Object library 12.0. (office 2007 equals version 12)

You can add reference to this COM library, and edit excel files.

Within this library are objects like an excel sheet, document, and application.

Hope it brings you a little further..
