Hello!
Sorry, it's not quite clear what you are trying to achieve. I don't see any pattern in your numbers. Could you please describe it in more detail? What result do you want to get?
I am creating a quiz bank. I want to find duplicates within a row and then be able to copy the formula down a column. I tried using the formula =IF(COUNTIF(C1:I1,), "duplicate", ""). However it only returns duplicates of the first cell. I need to know if ANY of the cells in that row are duplicates. Please help!
Hello!
If I got you right, the formula below will help you with your task:
=IF(SUM(--(COUNTIF(C1:I1,C1:I1)>1)) > 0,"duplicate","")
After that, you can copy this formula down along the column.
I hope it’ll be helpful.
It works perfectly! Thank you SOOOOOOOO much!
Sorry I just realized the formula i put in above is not the formula I am using. It is =if(countif(C1:I1,C1)>1 "duplicate", "")
If the range is not continious, example A1:A5 and B1:B15 then how to check if the 15 values in these cells have duplicate or not
Hello!
Unfortunately, Excel cannot search data in multiple data ranges at the same time.
Hey
How to paste data in a merge cell
Help me if u know
Hello!
I’m sorry but your task is not entirely clear to me.
Please describe your problem in more detail. Write an example of the source data and the result you want to get. It’ll help me understand it better and find a solution for you. Thank you.
Quick Question, Is there a way to set the 1st row of duplicate records to "Parent"
I am using this formula: =IF(COUNTIFS($A$2:$A,A2,$B$2:$B,B2,$C$2:$C,C2)>1,"Child","Parent")
Row 1 - Parent
Row 2 - Child
Row 3 - Child
instead of
Row 1 - Child
Row 2 - Child
Row 3 - Child
Help is greatly appreciated.
Hello!
If I understand your task correctly, you need to set the first occurrence of a duplicate as Parent" marking the rest of them as "Child".
Assuming that your table has no header, here is the right formula for you:
=IF(COUNTIF(A1:$A$26,A1)>1, IF(AND(COUNTIF(A1:$A$26,A1)>1, MATCH(A1,$A$1:$A$26,0)=ROW(A1)), "Parent","Child"),"")
If however, there is a 1-line header, the formula should be modified a little to look like the one below:
=IF(COUNTIF(A2:$A$27,A2)>1, IF(AND(COUNTIF(A2:$A$27,A2)>1, MATCH(A2,$A$2:$A$27,0)=ROW(A2)-1), "Parent","Child"),"")
Hope this is exactly what you need.
ok I have an excel worksheet that I want to add a formula to catch duplicates throughout the worksheet. I don't want the 1st selected column ex:A2 to change I want it to carry down to where it catches any above it, Say I am on row A 15 I want it to look at rows A2-A14 to make sure the information I added in A15 wasn't on any above it. Can you help with this please?
Good Afternoon!
I have a workbook spreadsheet (SP1) that is pulling data from another workbook spreadsheet (SP2) using an if statement formula. In SP2, column A, I'm pulling data from SP1, column G. I would like to highlight the row in SP2 if a duplicate is found in column A. However, I'm not sure if I can do that with there already being a formula in each cell.
To better clarify my question - Is there a way to highlight a row when the data pulled in column A duplicates, and to not highlight if no data is pulled or the result is "false".
My issue right now is that because there is a formula in every cell when I use conditional formatting it ends up highlighting the entire workbook. I only want it to highlight if column A shows a duplicate result (A1 formula result shows: a, A5 formula result shows: a).
Thanks, Svetlana
It was awesome.
Is there a way to find the exact location (using Index and Match) next to the first, second (and so on) duplicate value? Suppose Mary 100 and Donald 100 in a long list of names in column A and values in column B. Would it be possible using Index/Match to put "Mary" and "Donald" in the same order in Column C?
Hi,
I need to flag 1st duplicate and 2nd duplicate till nth duplicate with respect to date.
for ex: 01/01/2010 is having data with duplicates and using COUNTIF it can return 1st duplicate and then 02/01/2020 is having same data and I need to flag second duplicate vice versa.
I am using below formula
"{=IF(COUNTIF($A$3:A3,A3)>1,"NX","X")}
here "X" return with 1st duplicate value
I need to find out the duplicates for the below...anybosy pl help me..

Hi, I'm using the duplicate formula but trying to add an index part so that it shows up the duplicate reference. Where am I going wrong and how do I correct it? I have: =INDEX(E:E(IF(COUNTIF(F:F,[@WON])>1,"Duplicate","")),0)
I want to show the contents of the duplicate cell from column E, if it has the same contents as another cell in column F. So if row 3 has the same column F value as row 5, I want B3 to show the cell value from E5.
I hope this makes sense.
Thanks

Hi,
how can i get the duplication data for example i want the excel to read the data from 6 last alphabet of an email.
Highlight duplicate values across multiple worksheets.
I have a workbook with four worksheets. We are clearing out a storage center and listing the bins on worksheet "Empty Bins" as they become empty. Worksheets "Aisle 1", "Aisle 2", and "Aisle 3" list all the bins in the system.
How do compare the data on worksheet "Empty Bins" to the data on the three other worksheets to find and highlight duplicates? Thank you.
I have 55000 entries in a single column 10 digit numbers. I have to find duplicates. But the problem is the numbers may have difference by addition of excess 3 4 digits at the ending or starting.
If duplicate is there, then I want result as first value in row1 against duplicate name. Any one pls. help to get result as mentioned in column3
Eg, below.
Column1---Column2---Column3(RESULT)
1 -------Siva -------1
2------- Kumar -------2
3 -------Suresh ------3
4 -------Siva ------1
5 --------Kumar -----2
I have a row with header in row1, for example; Boat1, Boat2, Boat3, Boat4, Boat5 and numbers in the next row, 5, 6, 7, 5, 4. I want to identify the duplicate headers or header/number, which in this case is Boat1, Boat4 or Boat1/5, Boat4/5. Happy for the result to be shown in two separate cells.

Hello!
Could we make this:
COUNTIF($A$2:A2,A2) to work in ArrayFormula()?
When I try this
=ARRAYFORMULA(C1:C&COUNTIF($C$1:C, $C$1:C))
It shows a total number in each repeated cell like:
a 4
b 1
c 2
a 4
a 4
a 4
c 2
But I still need to receive
a 1
b 1
c 1
a 2
a 3
a 4
c 2
To have a full column with unique values based on another column with repeats.
Big thanks in advance.

Prakash:
Svetlana recently wrote a very good article on this topic. The article was published here on Ablebits on April 26.
Enter "Find duplicates" in the search box and you'll see the article "How to find duplicates in Excel: identify, highlight count, filter, and more". Click on that link and once you've read the article you'll be able to accomplish what you want.
Is it possible to get the number the duplicate in order that they appear?
For example
123,1
124
123,2
123,3
125
123,4

Are you asking to match the first three digits?
Dear Svetlana,

Is this possible?

Hi,
Thank you for all of the information on here.
I am experiencing a range limit on the use of this calculation? For some reason it is only letting me check 20 rows, anything above that is returning a result of 0. Is this normal?
What I really want to do is check an entire column in a table for values (there is about 1000), but as soon as i do this the returned value is zero. If it is less than 20, the returned value is acurate.
I am using;
=SUM(IF(ISTEXT(A28:A37)*COUNTIF(A28:A37,A28:A37)=1,1,0)) - works
=SUM(IF(ISTEXT(A:A)*COUNTIF(A:A,A:A)=1,1,0)) - total is zero
=SUM(IF(ISTEXT(A1:A37)*COUNTIF(A1:A37,A1:A37)=1,1,0)) - total is zero

I wish to find if some Teacher's name is repeated in Column A
Create three separate columns. First column has the class name, the second has the teacher's name and the third has another teacher's name.
Separate the teacher's names into two columns.
Then, in a fourth column enter =COUNTIF(B:B,B1)>1
The result will show "TRUE" if it is a duplicate.
If you want to see if the teachers in column C are duplicates, just enter =COUNTIF(C:C,C1)>1 into column D.
Thank you very much, Svetlana for these very comprehensive explanations about "duplicate issue" in Excel. I was trying to find out how to remove duplicates from the file and I have found an easy way in your article. All the best!

Hi, I'm trying to highlight, and so prevent duplicates in a number of cells. For example if I am designing an appointment time slot of 09:00, 10:00 and 11:00 across B22:B24 how can I get Excel to highlight that configuration if the same slotting is repeated/redesigned in AL22:AL24?
Hello,
I am using your array formula to count duplicates in a column. In it's current form, it also counts the empty cells as duplicates. Is there a way to make it ignore empty cells?
{=ROWS($A:$A)-SUM(IF( COUNTIF($A:$A,$A:$A)=1,1,0))}
My second questions is - Can you adjust the formula to make it ignore the original in the count?
For example, if a result in the column occured twice it would count two, but only one is the duplicate since the first is the original. I would like it to count only one for each pair or two there are three of the same value, etc.

For EX
we have a location
DEL-LON
LON-JFK
MCO-TPA
We have to find that DEL or LON or JFK or MCO or TPA are repeating how many times in each row.
Hello, pankaj,
I'm afraid there's no easy way to solve your task with a formula. Using a VBA macro would be the best option here.
However, since we do not cover the programming area (VBA-related questions), I can advice you to try and look for the solution in VBA sections on mrexcel.com or excelforum.com.
Sorry I can't assist you better.
Hi,
I am wondering if someone could help me?
I have some data with 2 columns of interest. One column is the case number and the other is number of days the case took to complete. Given the inadequacies of the search tool available, I have multiple duplicates for some of the cases. Not all cases are duplicated, and those that have been duplicated have been duplicated anywhere between 2 and 6 times. With each case duplicate, I have another time value generated. Some of these time values are the same for all duplicates, some are different, and they are not in numerical order.
What I am trying to do is for each case, to pick out the largest time value.
The example below might make more sense:
What I have- What I want-
CASE TIME CASE TIME
A 2 A 5
A 1
A 5
B 4 B 4
C 3 C 3
C 1
D 4 D 4
D 4
D 4
E 1 E 1
F 2 F 6
F 2
F 6
F 2
F 2
F 2
Hopefully someone can get further with it that I have been able to! Thank you in advance!
(sorry the example, but clearer hopefully!)
What I have-
CASE TIME
