To be honest, you really shouldn't:

"All current versions of Microsoft Office were designed, tested, and
configured to run as end-user products on a client workstation. They
assume an interactive desktop and user profile, and do not provide the
level of reentrancy or security that is necessary to meet the needs of
server-side components that are designed to run unattended."

As Patrick has said, don't even consider using server-side Office
automation - Microsoft don't support it because it doesn't work...

Fortunately, creating Excel documents from ASP.NET (which I assume is what
you're using) is fairly simple:

1) Use HTML
Create an HTML document and give it a .xls extention - Excel will treat it
like a native Excel document. This is very simple and (obviously) free, but
you are limited to a single worksheet.

2) Use OpenXML

Again, this is free, but is not for the faint-hearted... However, it will
allow you to create multi-sheet workbooks

3) Use Aspose

This is by far the simplest solution, but it's a commercial product...
