Kevin,
You can find a couple of examples about TestStand and Excel at the following web page:
http://search.ni.com/query.html?col=alldocs&layout=Example&qp=ContentType:Example&qt=%2Bteststand+%2Bexcel
However, most of these examples use LabVIEW or other programming language to communicate with Excel. Currently, we do not have any examples that deal with direct interaction with Excel from TestStand. However, the basic functionality of Excel's automation server can be found at the following library entry in Microsoft's MSDN:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_wrcore/html/wrgrfexcelapplicationobjectfunctionswindowsnames.asp
You can use this information to reference the proper objects and methods in your application.
