Step by step
- 1Enter =COUNTA(UNIQUE(A2:A100)).
- 2UNIQUE produces the distinct list; COUNTA counts those entries.
- 3The result is the number of different values in the range.
Tips
- Make the range tight (A2:A100, not A:A) so trailing blanks are not counted.
- In older Excel without UNIQUE, use =SUMPRODUCT(1/COUNTIF(A2:A100, A2:A100)) on a range with no blanks.

Frequently asked
How do I count distinct values, not total entries?
COUNTA counts everything; wrap UNIQUE inside it — =COUNTA(UNIQUE(range)) — to count only distinct values.
