I have a massive spreadsheat of MRP data for each partnumber in the system.
There are over 13,000 rows of data with fields going out to column BN.

I need to compare a list of known good data to an updated list to see if any
data has changed and if any new partnumbers were added.

I have tried the 4 TOPS software I found on this site but I don't really
trust it yet. It seems to be always running in the background even after I
shut it off.
