For those wanting to know how to do this in versions of Excel prior to XL2007, here is the Conditional Formatting formula to use. Select the cells in Columns A, B and C from Row 1 down to the last row you want to conditionally format and use this Conditional Formatting formula...
.
.
=SUMPRODUCT(--($A$1:$A$30&"X"&$B$1:$B$30&"X"&$C$1:$C$30=$A1&"X"&$B1&"X"&$C1))>1
.
.
Those embedded X's just need to be a character that is guaranteed not to be in any of the cells being conditionally formatted. These characters ensure no accidental matches occur during the concatenations; for example, without them, an accidental match could occur like this...
"12"&"3"&"4" = "1"&"23"&"4"
both equating to "1234" meaning the equality check would be true; with the X's in place, you get this...
"12"&"X"&"3"&"X"&"4" = "1"&"X"&"23"&"X"&"4"
with the first equating to "12X3X4" and the second equating to "1X23X4" and the equality check would be false.
Here is another conditional formatting formula, excel 2003:
=SUMPRODUCT(COUNTIF($A1, $A$1:$A$30)*COUNTIF($B1, $B$1:$B$30)*COUNTIF($C1, $C$1:$C$30))>1
When you modiy to move to anu other column apart from 'A' the the first instance of the duplicate also highlights.
David Gordon,
You are right, I believe the new formula I have added to this post is more useful.
Thanks for commenting!
this formula is not working for me.....
Deepak,
what does your formula look like?
Remember, you must understand how relative and absolute cell references work.

Thank you for the great post! I had spent almost a full day searching for how to highlight duplicates in a filtered list. But I have one further question. I am filtering this based on duplicate dollar amounts. How could I add in a part of the function to only highlight the duplicate amounts over $900 in the filtered table?
Oscar, Our company requires all employees to take 30 Mandatory Annual Courses. I have been tasked with streamlining the class schedule. I created in access a query that pulls all courses and personnel that are due to take these courses within 45 days. I export to excel and then sort on the courses and then the supervisor. After that I subtotal and get 30 subtotals for each course. The number of records in each subtotal course varies.
My max class size per course is 14 and the max number of people per supervisor is 5. How can I
Oscar,
My company requires all employees to take Mandatory Annual Courses.
We have 30 courses.
I have been tasked with streamlining the class schedule. I have all courses listed along with the names of the personnel along with their department and supervisor. I sort by class name and then by supervisor. I then subtotal and get 30 separate subtotals per course. Number of records in each subtotal will vary.
My max class size is 14 and the most I can pull from each supervisor per class per course is 5.
How can I create a formula for each subtotal that will determine the number of classes based on a max class size of 14 and then assign the max number of personnel per class per supervisor of 5.
Example: Course Name: Active Shooter
42 people need to attend this class, There are 6 supervisors for these 42 people. On the surface it looks like 3 classes,however one supervisor has 16 people which would exceed the max per class of 5.
Any help is appreciated.

Gene Haines,
My max class size is 14 and the most I can pull from each supervisor per class per course is 5. 42 people need to attend this class, there are 6 supervisors for these 42 people.
You only have 6 supervisors, don't you need more supervisors per class per course if your class is 42? If each supervisor has 5 people you get 6x5 = 30 people.
This criteria is not met if your class is above 30 people?
Hello, this formula works great, I am wondering if I can change it slightly for what I need.
I have rows of lists, 6 in each row. They are all names. The names will be in different order, but I want to not have duplicates of the same lists. I cannot fully sort them as the first name is unique, and needs to be in that spot. I will give you and example:
John Bill James Ron Joe Mike
Bill John James Joe Ron Mike
James Bill John Joe Mike Ron
All three of these list are the same, but when they are in a different order, this conditional formatting does not show them as duplicates. Any suggestions?
Thank you in advance,
Marsh
exactly what i was searching for. unfortunately way more cumbersome than i hoped, but a solution nevertheless. thanks a lot!
Hi,
I'm trying to find a way to highlight cells with text/number (column B) if reoccurred 3 times or more within the last 3 days (dates in column A)
I hope someone can help
Hello,
I'm doing this for a spreadsheet where I don't want a blank cell (in the second column) to match with another blank cell. How can I modify the formula accordingly? For instance, in my work I drag down the dates in column A before entering the rest of the data. I'm looking for a match between column A&E between rows. But at the moment it does this, but also highlights all the prepped rows at the end where I've dragged down the date. I want it not to consider the same date in A and a blank in E to be a match with another same date A and blank E.
Thanks!
