# 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

and with your original frequency function  here is the formula

enter with control shift enter

=SUM(IF(FREQUENCY(IF(LEN(A1:A200)>0,MATCH(A1:A200,A1:A200,0),""), IF(LEN(A1:A200)>0,MATCH(A1:A200, A1:A200,0),""))>0,1))
