G'day MynameisAchint,

Welcome to the monastery.

While I realise this is your first posting here, unfortunately it has some problems. Please read "How do I post a question effectively?". Do note that PerlMonks is not a code writing service; if you want to post a specification and then sit back while someone else writes your code, you'll need to look elsewhere.

It's unclear from your post whether you're using Excel purely as a reader for CSV files or if Excel has a more integral role. If the former, you can bypass Excel altogether and use Text::CSV; if the latter, you'll need to identify whether you're working with the older (*.xls) or newer (*.xlsx) format and then use (probably) either Spreadsheet::ParseExcel or Spreadsheet::XLSX.
