Had you read rather than glanced at the PerlMonks FAQ and How do I post a question effectively? you may realised that you could do a lot to help us help you. You have not given us a lot of information. For example you fail to mention which operating system you are using? If it is Microsoft Windows you should be able to use Win32::OLE to control Excel (see Re: Excel VB Controls for some useful links on this topic).
Again, a super search would have shown this method of manipulating Excel.
