Hi, Where can I find the docuemntation on what methods are available for Excel? I tried AddComment and it worked. But I need molre functionalities like adding fill color, deleting comments etc. I tried: $Sheet->Range("c8:c8")->SetFill("Red"); and it failed. I read the Win32::OLE documentaiton but that does not give Excel specific methodd details. Regards, -Monir
