Subtotal?

[EOAEvan]

It seems I should be able to do this with subtotal but am not getting the correct answer. I have a list of data from a .txt file that is imported into excel. I need to be able to count the number of unique instances an account number is displayed....

Example of imported list

1234
1234
1234
1235
1235
1236

The desired result would be 3 total unique instances:

1234....1
1235....1
1236....1


It does not matter if this is done via VBA, a formula (dont know how that would work) or a function.

may have just answered my own question... If the account numbers start in B1 and go down... place a 1 in A1 and this formula in A2

=if(b2=b1,0,1)


then sum at the end of column A


I am looking for other solutions if they exist.

A pivot table is perhaps a possibility
