Help: Highlighting Only the First Duplicate
Select B1:B9 (or to the end of the data). B1 should be the active cell in the selection.
Create a rule of type 'Use a formula to determine which cells to format' with formula
=AND(ISNUMBER(MATCH(B1,A:A,0)),COUNTIF(B$1:B1,B1)=1)

I have tried all of the formulas but none of them are working. I am working with dates, does that make a difference?
Bu sure you correctly use first cell of the range to apply in formula, in general it shall work
Here first of duplicated values is highlighted and any value without duplicates.
That worked perfectly. Now is there a way to highlight the first of any duplicates in a column? In this spread sheet there are groups of rows that have #s that I need to highlight the first of each new group of duplicate numbers. The last calculation does not work as it only hight lights the first # that is a duplicate, not the first of the group of duplicates. if that makes sense.
HansVogelaar - I tested it with the sample text, and it works. But I'm having difficulty applying it to my project. The columns contain email addresses along with some appended (concatenated) text to serve as a unique identifier.
Originally, I had an asterisk between the date (first 8 characters) and the email. I thought it might be interfering, so I replaced it with "ZZZ" and can remove it later. I then thought the "@" was the problem, so I replaced that with "XXX" and can remove that later. Regardless, the formula you suggested should work here, right? It doesn't, and I can't figure out why not.
In writing this, I also replace the period in ".com" just to see. Nothing. Still doesn't work. It's just text, so why isn't it being recognized as a match?
Could you attach a sample workbook, or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?
