Excel Automation Documentation

I am new to Navision, been working with it less than three months, and need to start working with Excel 11.0 Automation Server. I’ve searched forums and support sites and have found some code, mostly for VB, but can’t find any documentation. I have even looked in the VB Script of MS Excel, as I read there was help files in there, but I couldn’t find anything. Is there somewhere I can go to find the ussage and syntax for Excel Automation?
