Hello! Me again, with another silly question…

I need a formula to calculate difference between 2 dates but if i put in the formula and drag it all the way down to infinity, it will use my 500/500 rows, i want the formula to trigger only when data exists, as in some sort of conditional format to only activate the formula when data in the row exists - is there a work around other than just an =IF formula?

I swear I looked…
