Hi
I think this is pretty simple, it's just that excel formulas break my brain.

I have Column D in Sheet1, and I have Column D in Sheet2. Both columns are for email addresses.

I want to compare the two for duplicates to determine what to delete from Sheet2. I presume countif or similar would work fine by outputting a column of the count, and then I delete all rows greater than 0.

Would someone help me with the best syntax please?

Test for Multiple Conditions in IF?
Use AND(test, test, test, test) or OR(test, test, test, ...) as the logical_test argument of IF.
oh i might have it actually:

Excel Formula:
COUNTIF(sheet1!D:D,d2)
