Counting Values

[Guest]

Hello All

Yet another problem ... have spreadsheed with multiple rows of data, however
I am looking to find a way of counting unique entries ...

ie data in colums such as ... 123 234 345 456 123 345 789

I am looking for a count function to tell me that there are 5 different
indivdual values within this set ... not lookking for number of entries just
identifying the different unique individual entries

Many Thanks

Alan

Hi
try:
=SUMPRODUCT((A1:A20<>"")/(COUNTIF(A1:A20,A1:A20)+(A1:A20= "")))

Thanks Frank ... however that didnt work for me here ... some of my sheets
also contain more than 20 rows

Hi
then just change the range reference. e.g. change
A1:A20 (all occurences) to
A1:A100 (or whatever is required)

Assuming the data are in A1 to G1 and always numbers.

=SUM(N(FREQUENCY(A1:G1,A1:G1)>0)) returns 5

If a mix of numbers and includes blank cells see Chip Pearson's site for
counting uniques in a range with more complex parameters.

=SUM(N(FREQUENCY(A1:G1,A1:G1)>0)) returns 5

....

Fewer nested function calls is usually better.

=COUNT(1/FREQUENCY(A1:G1,A1:G1))
