This is an array formula and must be entered with control + shift + enter Because we give EXACT a range of values in the first argument, we get back an array result containing TRUE FALSE values: This array goes into the AND function, which returns TRUE only if all values in the array are TRUE.

### Ignore empty cells

To ignore empty cells, but still treat non-empty cells in a case-sensitive manner, you can use a version of the formula based on SUMPRODUCT: Here, we count exact matches using the same EXACT formula above, get a total count with SUMPRODUCT, and compare the result to a count of all non-empty cells, determined by COUNTA. This is an array formula but control + shift + enter is not required because SUMPRODUCT handles the array natively.
