Hello,
Can you help me with my problem?
How to remove duplicates in different column?
original data It's like this:
1 1 5 5 5 3 4 4
and turn to this:
1 5 3 4
Remove the duplicates but retain the 1st one.
Thank you in advance.
Hello!
All duplicate detection methods require data to be arranged vertically in columns. Therefore, first, transpose the data as described in this guide. Then remove the duplicates. For detailed instructions, see this article. Then transpose the data again.
Thank you so much this was such a huge help!

Hi!
What does "separate the duplicate" mean? Have you tried the ways described in this blog post? If they don’t work for you, then please describe your task in detail, I’ll try to suggest a solution.
Thank you Alex!
In my previous comment, there are two items. Item 1) has all the records, while item 2) the duplicates have been separated on same excel sheet. How can i achieve that and still keep both records in same sheet?
Hi!
Use the Duplicate Remover to move the duplicates onto a separate sheet. Then, if necessary, move them to the original sheet in the desired place.
Thanks
This is great! However, I'm thinking of multiplying a certain no. or cell using if function for duplicates. Say if k3 cell duplicates within k1:k6, e3*85%, otherwise e3=100%.
Tried using this --> [=another formula*(if(countif(k1:k6,k3)>1,e3*0.85,e3*1)] but sadly errors.
Would anyone know how to go about this? Thanks in advance!
Hello!
This formula works for me.
=(A3+A4)*IF(COUNTIF(K1:K6,K3)>1,E3*0.85,E3*1)
If you get an error, please describe the problem in more detail.
You're Godsent. Got why it errors. I doubled the multiplication in the formula. Thanks so much! :)
how can we identify the duplicate location/reference designators in the different rows?
Example

Hello!
Split each cell. Use a comma as a separator. To do this, you can use the Split Text tool. Use Duplicate Remover - Find Duplicate Cells tool to find duplicates. It is available as a part of our Ultimate Suite for Excel that you can install in a trial mode and check how it works for free.
If something is still unclear, please feel free to ask.
Using a formula(s), is there a way to find duplicate rows with multiple columns but info in columns are not necessarily in the same order.where the examples below are considered duplicates even if they're not in order?
A B C D
LAX SFO ATL DUPLICATE
PDX ATL LAX
LAS ATL LAX
JAX LAX PDX
SFO ATL LAX DUPLICATE
JAX LAS MCI
Hello!
You cannot do this with a formula. Use Duplicate Remover.
Hello,
First, great tutorial, very useful. I applied some of the formulas to solve a situation. I just needed to know if the data I load into an Excel table is duplicated, I don't need to know which rows are repeated, just to know the data is wrong so I can go to source to solve a problem I didn't know existed. The approach of the array formula that does not require a helper column seems the best option:
=ROWS($A$2:$A$8)-SUM(IF( COUNTIFS($A$2:$A$8,$A$2:$A$8, $B$2:$B$8,$B$2:$B$8)=1,1,0))
But then I came across a situation. Sometimes one of the columns can have a blank value, when that happens the formula identifies that row as not unique and returns a wrong value. I could fix the situation with this formula:
=ROWS($A$2:$A$8)- SUM(--( COUNTIFS($A$2:$A$8,$A$2:$A$8, $B$2:$B$8,choose({1,2},$B$2:$B$8,""))=1))
As you can see, I added the "choose" function with {1,2} as the index num so the "Choose" function returns both, the complete range that is used as criteria plus the empty space value "" counting correctly the blank cells when needed.
Another change I did was the use of "--" instead of the "if" function, but that doesn't change the result.
Hi,
I have 1500 lines data, I have to identify the duplicate with B collom and C collom,if that should match cell details and C cell details,how can I apply the formula for identifying the duplicate with same details matching with more than one.
Hi! It's hard to tell exactly what you're asking for as it's currently written. Pay attention to the following paragraph of the article above: How to find duplicate rows in Excel. Or explain your problem in more detail.
Dear Sir/Madam,
Is there a way to find duplicate values in a single cell in MS-Excel? I'm working on a CSV file where there are duplicate values occurring in a single cell only. Can you please help?
Hello!
You need to split the text from this cell into other cells. You can then look for duplicates in these cells.
I recommend using the Split Cells tool for this.
Duplicate Remover will help you find duplicates in cells.
It is available as a part of our Ultimate Suite for Excel that you can install in a trial mode and check how it works for free.
How to find last 4 digit duplicate value and marked. is there any formula. e.g.
JVC2020TDL2946
BV2020TDL2946
JVC2020TDL2947
BV2020TDL2947
JV2020TDL0224
JV2020TDL0225
Hello!
You can extract the last 4 digits into a separate column using the RIGHT function. Then look for duplicates in that column as described in the tutorial above.
I hope this will help, otherwise please do not hesitate to contact me anytime.
Thanks Sir
for your reply and i have also tried this option it will work properly.
I know that this is old but the easiest solution would be to highlight a column, go to conditional formatting->highlight cell rules, then duplicates. After that, just filter by color.
To rmove them, there is a built in button in excel, under the data tab.
How to choose repeated number example for this case:
12344445678910444. The correct answer is 4
Hi, I need to modify the formula that extracts ONLY duplicates from column to make it able to work from the first row.
=IFERROR(INDEX(A$2:A$16,MATCH(1,COUNTIF($A$1:A1,A$2:A$16)=0)*COUNTIF(A$2:A$16,A$2:A$16)>=2)),0)),"")
As you can see it doesn't allow to be placed in the first row due to cell reference problem in this part COUNTIF($A$1:A1,A$2:A$16).
Is there any alternative option?
Hi
I hope you are doing very well.
Your solutions are very helpful.
Thanks a lot.
hi, how to find duplicate from 2 sheets and highlight with color
Hello!
All the recommendations you need are listed in the article above. Make external references to another sheets of your workbook correctly as described in this guide.
I am trying to count how many duplicate names are found in Col A. I have 600 plus rows and I just want the count each time I find a duplicate value. I tried
Column B
=COUNTIF($A$2:$A$800, $A2)
Column C
=IF(COUNTIF($A$2:$A$800, $A2)>1, "Duplicate", "Unique")
But I only return 722 value in Column, and only Duplicate in Column C (used to remove Duplicate, just leave one count total.)
Im looking for:
Appels 121
Grapes 253
Bananas 10
Oranges 400
Is this possible? Any kind help?
Hi,
I don't really understand what you want to find. To remove duplicates, it is best to use a formula that ignores the first occurrence of the value. See "How to search for duplicates in Excel without 1st occurrences". To remove duplicates, I recommend using Duplicate Remover Toolkit for Excel. It is available as a part of our Ultimate Suite for Excel that you can install in a trial mode and check how it works for free.
If this is not what you want, please describe the problem in more detail. I will try to help.
Hi,
I would need some help regarding this issues:
1. I have a list with names, I had found the duplicates. My task is: Using a single formula, detect all of the duplicates in the above list. If the term has already appeared in the list, then your formula should display it on the same row, if the term has not already appeared on the list then your formula should display N/A.
Name
Cristina
Ioana
Florin
George
Cristina
Cosmin
Neculai
Alina
Florentina
Andreea
Laura
Alina
2. I need a formula for completing this task: Create a formula that returns only the characters that appear after "X" for the given character strings. The same formula must work for the whole column!
Example: 45629X421 421
Hello!
I hope you have studied the recommendations in the tutorial above. It contains answers to your question.
To return all characters after "X" use the formula
=MID(B1,SEARCH("X",B1,1)+1,100)
I hope it’ll be helpful.
I found the formula for task 2.
Any thoughts for the 1st task?
Thanks!

Hello!
If I understand your task correctly, the following formula should work for you:
{=IFERROR(INDEX($B$2:$B$12, SMALL(IF($D2=$A$2:$A$12, ROW($B$2:$B$12)-1,""), COLUMN()-4)),"")}
This is an array formula and it needs to be entered via Ctrl + Shift + Enter, not just Enter. Line 1 is the title of the table. Column A is a list of websites. Column B is a list of names. Column D is the website where you want to find the names of colleagues.
You can read more about this formula in the article: How to VLOOKUP multiple values in Excel
You can combine names in one cell with delimiters using the formula
=TEXTJOIN("-",TRUE,J2:N2)
I hope my advice will help you solve your task. If something is still unclear, please feel free to ask.
Hello,
sorry, how to find the last duplicate value in row ,
such as:

i want to find the number "2" that is from column "D"
tnx..
Hello!
If I understand your task correctly, the following formula should work for you:
=IFERROR(INDEX((IF(COUNTIF(A1:F1,A1:F1)>1,A1:F1,"")),,MATCH(TRUE,(IF(COUNTIF(A1:F1,A1:F1)>1,A1:F1,""))<>"",0)),"")
I hope I answered your question. If something is still unclear, please feel free to ask.

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", "")

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'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.
