I've hardly used Win32::OLE, I'd suggest following the advice in the documentation which suggests referring to the Object Model documentation for the Microsoft Office application in question. It's important to understand what Win32::OLE is, and how to use it. If I were given this task, like your previous question, I'd avoid using Win32::OLE to automate other applications. As previously suggested, I'd use a combination of MIME::Lite and Spreadsheet::ParseExcel.
