New/removed entries from excel/csv extracts

[Anonymous]

Hi Guys, every month i download this high volume extracts of 7/8 flat files consisting columns of asset information and their unique ids. It doesn't have any date column. Is there any way i can track all the new and removed entries from my last extract every time.
Thanks in advance.

<---- Could you clarify more details about your requirement or share some sample data?
