How to count the number of unique entries in a filtered column

[learnlearn52]

Perhaps this may have been answered before. I used formulas from the
Discussion Groups but did not get the right answer. I have the following
filtered data (alphanumeric) exactly:

A100
A102
A104
A103
A108
A104
A102
A102
A103
A109

The total number of entries is 10 and the unique number of entries is 6.What
formula should be used to calculate the unique number of entries? Thanks in
advance

Try this

=SUMPRODUCT((A1:A10<>"")/COUNTIF(A1:A10,A1:A10&""))

If your filtered list is in A2:A200 try with CTRL+SHIFT+ENTER:

=COUNT(1/FREQUENCY(IF(SUBTOTAL(3,OFFSET(A2,ROW(A2:A200)
-ROW(A2),)),MATCH(A2:A200,A2:A200,0)),ROW(A2:A200)-ROW(A2)))
