I'm looking for a way to count unique values for the whole column (A:A).
Currently, I'm only able to write formulars like A1:A10 which does the job. However, when changing to A:A is returns #DIV/0
The formulars I'm currently using are:
=SUMPRODUCT(1/COUNTIF(A2:A607;A2:A607))
and
=SUM(IF(FREQUENCY(MATCH(A2:A607;A2:A607;0);MATCH(A2:A607;A2:A607;0))>0;1))
