Cool data analysis tool for excel

I stumbled unto a new tool that I used for a data | business information consulting that I recently completed and I want to share it with the world.

This tool will add posix based regex capabilities to excel. This is such a huge improvement to excel that you have to scream it from the roof tops. Get the software at http://xcell05.free.fr/morefunc/english/ or download it from the attached file (might be an older version by the time you read this).

Works with excel 2000 - 2007

I may go into detail on how to use the functions in my notes section.
