You were closer, but I really meant:

=A1&TEXT(COUNTIF(A$1:A1,A1)-1,"0;;;")

(not A4 as the first cell reference)

(I was cleaning up $ signs and got too aggressive!)

Add a unique (sequential) number at the end of usersnames


Greetings All,

I have several hundred usernames that are identical (ex. 50 "mjones"). I
want to be able to use excel if possible to place a unique and sequential
number at the end of the duplicates (after the first original of course).

I was able to create a worksheet with "Concoctonate=Conditional
Formatting=True&False=Sorting"... Now just looking for a way to automate
the "adding of unique numbers" at the end of the username.... Any advice...?

Thank you!
Sawtelle
