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.
Thank you

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
Frank:
I don't see any duplicates in this data.
Are you asking to match the first three digits?
Dear Svetlana,
I hope you can help me with the following question.
I have a list of cities and some of them are repeated in the list. I would like to extract the row reference of all repeated city names (i.e for a given city: New York - is repeated in row 2, 7, 29, 33 etc).
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

Dear Sir/Madam
Please help
I have following data.
A1 = Maths/Bio. Gurpreet,Sandeep
A2 = Physics Kuldeep
A3 = Economics Priyanka
A4 = Maths/Physics Gurpreet, Ramesh
It's a school time table
As I type the name "Gurpreet" in B1 it shows me duplicate
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.
D
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
A 2
A 1
A 5
B 4
C 3
C 1

Dear Svetlana.
I have an issue regarding to duplbicates in Excel.
Name Number of apples
Anne 2
Anne 8
Anne 5
Eric 14
Eric 7
What I want to do is to sum up all the number of apples given each name.
So I need the result to be Anne: 15 apples and Eric 21 apples. Do you know how to calculate this? I have used the Sumifs function, but I get this result:
Name Number of apples Total number of apples each person
Anne 2 15
Anne 8 13
Anne 5 5
Eric 14 21
Eric 7 7
So my question is, how can I use a function that just gives me the sum of number of apples every person without showing the sum of the other rows. So I want the result to be this:
Name Number of apples Total number of apples each person
Anne 2 15
Anne 8
Anne 5
Eric 14 21
Eric 7
I would appreciate your help.
Best regard,
R.R.
Dear Rouzbeh Rasai,
The reason why you get the wrong result using SUMIFS function is probably that you did not use absolute cell reference.
Try this formulas:
=SUMIF(A$2:A$6,"Anne",B$2:B$6)
=SUMIF(A$2:A$6,"Eric",B$2:B$6)
As for the result you want to receive, to get it you need to create a VPA macro.
I have collected data from several production batches about the duration of a certain process step.
batch 1 3.4 hours
batch 2 3.6 hours
batch 3 2.8 hours
batch 4 3.1 hours
batch 5 3.5 hours
batch 6 3.1 hours
batch 7 3.6 hours
In the example above, the lowest repeatable duration is 3.1 hours. So, this could be an achievable standard duration for this process step. The following array formula obtains the lowest repeatable duration.
={MIN(IF((COUNTIF($A$1:$A$7;$A$1:$A$7)>1);$A$1:$A$7;MAX($A$1:$A$7)))}
Now, I'm having problems with the next step. The following durations first need to be rounded to 1 decimal, before the lowest repeatable can be found.
batch 1 3.412 hours
batch 2 3.629 hours
batch 3 2.834 hours
batch 4 3.101 hours
batch 5 3.506 hours
batch 6 3.097 hours
batch 7 3.611 hours
Is there a way to incorporate rounding of the numbers into this array formula?

I have a spreadsheet with 12,000+ rows that I need to de-dupe. I want to identify the dups, and mark some of those for deletion. My columns headers are: EEID, EEName,CLP1,CLP2,CLP3 - through CLP12
The EEID and EEName columns definitely have duplicates. I want to delete only the records that have blank CLP1 columns.
Example:
EEID EEName CLP1 CLP2
1234 Diana
1234 Diana Analyst Rover
As long as Diana doesn't have any data in the CLP columns, her record can be deleted.
Which formula should I use?
Hi !
I have a problem: i don't know how i find the duplicates with exceptions. For ex.: 1,2,3,2,3,4,2,1. I want to color the duplicates without "1". Can you help me?
Thank you,
Ciprian
Thank you so much!
Hi!
This article seems to be very interesting, but I have noticed that the formula syntax in my MS Excel is different.
In particular it is:
=COUNTIF(range; criteria)
For example:
To count how many times the value in A1 is repeated in the range A1:A100 the working formula works is:
=COUNTIF(A1:A100;A1)
Then, I suppose that the syntaxes are different and it seems to me that they follow diffent criteria.
In fact, if I used the first formula you indicated, that is
=COUNTIF(A:A, A2)>1
in my MS Excel doesn't work.
Could you help me to understand which criteria I have to use to translate you syntax?
Thank you so much
Ivan
Hello, Ivan,
as you may notice, the arguments are divided by semicolon (;) in your formula, while in ours – by (,) comma. It may happen due to the regional settings for the list separator. Try the formula below and read this topic to find out more.
=COUNTIF(A:A; A2)>1
Using a formula above, I was able to identify duplicate and unique rows based upon 3 separate columns (Barcode, Custodial Account, OSVer) in my spreadsheet. Now that I have the rows identified, I need a formula that will keep only the unique rows where the Barcode and OSVer are duplicates, but the Custodial Accounts are different based upon the most current date contained in the LastHWScan column. My spreadsheet has 50000 rows of data and will change daily.
Barcode CustodialAcct OSVer LastHWScan

315396 11376 10 3/15/2017 14:41
The formula can't change the data in another cell. You can create an additional 'Helper' column and, using the next formula, indicate unique rows (CTRL+Shift+Enter to create an array function):
=IF(D2=MAX(IF( ($A$2:$A$15=$A2)*($B$2:$B$15=$B2)*($C$2:$C$15=$C2)=1,$D$2:$D$15,0)),"Unique","")
As a result, you will have something like in the example below. But it will run slow within a large data amount.
