I am not sure what is best way to approach the project but I know there is a simple tactic to take to take one column from an Excel SS and via software or a script, to add a "-1" then "-2" then "-3" etc. to any SKU#s in the column that are duplicates.
IE: If there are 3 rows / cells like:
98659
98659
98659
I need the cells re-written to read:
98659-1
98659-2
98659-3
