noobie needs help with SP - Livin

I have no idea where to start. Usually I can do a web search but this
one is not so obvious with search terms. And, I've never built an SP,
only basic queries and used excel formulas but this it too complicated
for excel.

I have an Excel workbook of software application names and versions.
Many have the same 'root' name but different version number.

e.g.  root = "McAfee VirusScan"

I need to find out all the 'matching' names and list each version that
exists, and count # of each version

There are thousands of items so I will not know what all the possible
versions are so I'd like to do this problematically.

Anyone do this before and have some example code or formulas?

Thx a ton!
