"...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.

There are some folks who find a straight jacket comfortable especially as it doesn't allow scratching unseemly itches, and others who like the freedom to decide for themselves which itches are worth scratching. Python and Perl users tend to live in quite distinct camps. The Python police state subscribes to the "One true way" mantra, whereas the Perl anarchy pledges obedience to TIMTOWTDI.

And yes, we do like to think PerlMonks is by far the friendliest and most supportive of all the language specific support sites.

One of the significant advantages of Perl is the CPAN. Other languages have an equivalent, but Perl's user contributed library is the prototype for such things and is more extensive than any similar library I'm aware of for other languages.
