I'm not sure if it comes standard with Visual Studio, but on your References dialog, underneath the COM tab there should be a listing for Microsoft Excel [version #] Object Library, or similar. You can add a reference to that and create Excel applications/files.

@Dhaest -- Yeah I wasn't sure about that, but I could have sworn I saw a download for an Office SDK that was independent of the suite. But I can't find it now. No visit from the SDK fairy this time  :(
