1. Select a blank cell next to the compare cells, and type this formula =AND(EXACT(E1:E6,F1:F6)) into it, press Enter key, then drag the auto fill handle down to the cells. And False means the relative cells are not duplicate in case sensitive, and True means the cells are duplicate in case sensitive. See screenshots:
