Welcome to perlmonks! This is a wonderful place to discuss all things perl - including learning perl. However, it's a really poor place to have someone do your work for you. (In fact, most places are, at least the ones you don't pay for.) So the question is, what have you tried so far?

I'll give you some hints to get you started, though: check out Text::CSV or Spreadsheet::WriteExcel for the writing part, and DBD::MySQL for the reading part.
