how to use regex to pull out names and then calculate numerical totals for each name?

Last Modified: 2010-06-12
i need to calculate the total for each person from a spreadsheet

I have a spreadsheet of data.

i have a list of dollars raised for various fundraisers
date, total amount donated, location, friends who were present at the fundraiser

April 2006, $350, School A, Jane, Tom, John, Sue, Ellen
May 2006, $425, School B, Jane, Tom, Sue, Mike

I want to for each person, go through this row by row, print out which fundraiser they were at, and then create a total of sums raised for all the fundraisers they were at.

Jane, School A, 350
Jane, School B, 425
total for Jane  775

Mike, School B, 425
total for Mike  425

I have hundreds of people and hundreds of events
My data is in a spreadsheet in columns.  All the donors are in one column, with the names comma separated.

I can output the data to a text file.

What should I use to get results I want?

I am guessing Perl
What would the code be?

Thank you very much.

great!  the output list is sorted alphabetically.  can i have it sorted descending by total please?  

also right now each company takes up 3 lines.
including the blank ilne

is it possible to have everything on one line, no blank, so it will only take 1/3 the number of pages.

thank you!
