"...so, may be perl can do excel stuff too?"

It sure can. Search MetaCPAN for Excel and CSV.

A module I use often, in a commercial environment, is Text::CSV. If you choose to use that, I'd recommend installing Text::CSV_XS also, as it will make Text::CSV run faster.

"Lemme check that on google."

When searching for anything related to Perl, I generally follow this order:

1. Perl core documentation — that's extensive so I'd suggest starting with perlintro just to get your feet wet; it's peppered with links to additional information, advanced topics, and the like, which should give you a feel for the documentation layout.
2. Perl core modules — you can navigate here from the previous link.
3. MetaCPAN — Perl CPAN modules.
4. Super Search on this site.
5. A general Internet search. Search engine results typically show links with the most hits first; unfortunately, that means they tend to be older and, therefore, less up-to-date. This is usually a last resort for me; although, just yesterday, I found "Perl/Tk Transparent Icons" (13 years old, and I needed to adapt some older instructions for more recent software, but it got the job done in the end).

That's a non-exhaustive list; it's really intended as a starting set of guidelines for you. I have lots of other Perl-related bookmarks that I use as appropriate; you'll no doubt build up an equivalent set geared towards your needs and interests.
