I would like compare data using a certain column to key off of and compare whether data has changed.
I have 5,000 rows and 26 columns. Cell C1 is CALLED PMNUM, cell I1 is called CHANGEDATE
I want to find all of the same PMNUMs (C2-C5000), look at the last change date (I2) (sorted in descending order), compare it to the previous change date (I2) and if anything has been changed in columns D2 through G2 and J2 through Z2 compared to the last time the data was reported, list the changes in in AA2.
I have attached the spreadsheet. Help
