Hi,
I have a set of data showing cumulative totals monthly. in e.g. in column for December( is cumulative of Jan to November). Is there a formula to subtract each month from previous month figures.
I'm using the copy --paste special -- subtract columns-and its taking ages and not efficient. I need to solve this very badly.
Is there any easy way/formula to subtract previous columns?
