If you have Excel loaded on the web server, you can create an instance of the engine and manipulate documents from there. I have done something similar with Word in the past where I needed extract metadata/information that was not available when converted
to RTF, for example. Specific technical details will take some digging up, so if you really need it let me know and I will go hunting (Googl... err, MSN Live Search <grin> worked great in finding info). You will want to keep open Excel programming reference
(it's installed with Office if you do the full install, just look for the CHM that is named appropriately).
A site like
http://www.thescarms.com/dotnet/ExcelObject.aspx, if it doesn't help you outright, should get you enough of the nomenclature to at least get started in you... um... search engine adventures.
