In my asp.net dynamic data project I want to read an excel file using suitable Microsoft technology (Not Excel). Someone said their was a server side tool for this? I want to read the first few columns of data from a table?
Any suggestions or directions on where to go?

Yes, Excel files are encoded in XML.
So to get started you can include following namespaces in the codebehind of your page:
System.Xml (work with XML objects)
System.IO (read/write to files)
The Internet is full of code example that show you how to use them.

It depends on the version of Excel format the file is saved in. If it's in 2003 and below, it's a multiple stream binary file that will be just about impossible to decipher. If it's 2007 and above, it'll be a .ZIP format file with multiple XML files inside of it. Again, a royal pain to decipher without the SDK. Seriously, save yourself MONTHS of work and use the Visual Studio Tools for Office to do this.
