Count unique values in Excel

Question

I need to count unique values in range (C2:C2080) in excel. Googled formula:

=SUM(IF(FREQUENCY(MATCH(C2:C2080;C2:C2080;0);MATCH(C2:C280;C2:C2080;0))>0;1))         


        

Answer 1

Try:

=SUM(IF(FREQUENCY(C2:C2080,C2:C2080)>0,1))

EDIT: The above will handle blank entries in the column
