# Frequency Function

I'm using this formula: =SUM(IF(FREQUENCY(A1:A200,A1:AD200)>0,1)) to count unique numbers in column A.

I noticed that if a letter(s) proceed numbers it does not count. I'm assuming this is correct for this function.

Is there a way to modify the formula to count unique "cells" if either numbers or letters? or another solution all together.

Thanks

=SUM(IF(ISBLANK(A1:A200),0,1/COUNTIF(A1:A200,A1:A200)))
assuming your data is from a1 to a200   feel free to change the range in formula
enter with Control + Shift + Enter
Microsoft Excel ExpertCommented:
also with just simple enter  =SUMPRODUCT((A1:A200<>"")/COUNTIF(A1:A200,A1:A200&""))
