*In this tutorial, you will learn how to show duplicates in Excel. We are going to have a close look at different methods to shade duplicate cells, entire rows, or consecutive dupes using conditional formatting. Also, you will see how to highlight duplicates with different colors using a specialized tool.*

Last week, we explored different ways to identify duplicates in Excel. Undoubtedly, the duplicate formulas are very useful, but highlighting duplicate entries with a defined color could make data analysis even easier.

The fastest way to find and highlight duplicates in Excel is using **conditional formatting**. The biggest advantage of this method is that it not only shows you the existing dupes, but detects and colors new duplicates as you input, edit or overwrite your data.

Further on in this tutorial, you will find a number of ways to highlight duplicate records depending on your specific task. These techniques work in all versions of Excel 365, Excel 2019, Excel 2016, Excel 2013, Excel 2010 and lower.

For starters, in all Excel versions, there is a predefined rule for highlighting duplicate cells. To use this rule in your worksheets, perform the following steps:

- Select the data you want to check for duplicates. This can be a column, a row or a range of cells.
- On the
*Home*tab, in the*Styles*group, click*Conditional Formatting*>*Highlight Cells Rules*>**Duplicate Values…**

- The
*Duplicate Values*dialog window will open with the Light Red Fill and Dark Red Text format selected by default. To apply the default format, simply click*OK*.

Apart from the red fill and text formatting, a handful of other predefined formats are available in the dropdown list. To highlight duplicates using some other color, click *Custom Format…* (the last item in the drop-down) and select the fill and/or font color of your liking.

Using the inbuilt rule, you can highlight duplicates in one column or in several columns as shown in the following screenshot:

When using Excel's inbuilt rule for highlighting duplicate values, please keep in mind the following two things:

- It works only for individual cells. To
**highlight duplicate rows**, you would need to create your own rules either based on values in a specific column or by comparing values in several columns. - It shades duplicate cells including their first occurrences. To highlight all duplicates
**except****for first instances**, create a conditional formatting rule based on this formula.

To highlight 2^{nd} and all subsequent duplicate occurrences, select the cells you want to color, and create a formula-based rule in this way:

- On the
*Home*tab, in the*Styles*group, click*Conditional Formatting*>*New rule > Use a formula to determine which cells to format*. - In the
*Format values where this formula is true*box, enter a formula similar to this:

`=COUNTIF($A$2:$A2,$A2)>1`

Where A2 is the top-most cell of the selected range.

- Click the
*Format…*button and select the fill and/or font color you want. - Finally, click
*OK*to save and apply the rule.

If you don't have much experience with Excel conditional formatting, you will find the detailed steps to create a formula-based rule in the following tutorial: Excel conditional formatting based on another cell value.

As the result, the duplicate cells excluding first instances will get highlighted with the color of your choosing:

To view duplicates beginning with the Nth occurrence, create a conditional formatting rule based on the formula like in the previous example, with the only difference that you replace >1 at the end of the formula with the required number. For example:

To **highlight 3 ^{rd} and all subsequent** duplicate instances, create a conditional formatting rule based on this formula:

`=COUNTIF($A$2:$A2,$A2)>=3`

To **highlight 4 ^{th} and all subsequent** duplicate records, use this formula:

`=COUNTIF($A$2:$A2,$A2)>=4`

To highlight only specific occurrences, use the *equal to* operator (=). For example, to **highlight only 2 ^{nd} instances**, you would go with this formula:

`=COUNTIF($A$2:$A2,$A2)=2`

When you want to check for duplicates over multiple columns, not by comparing the columns to each other, but find all instances of the same item in all the columns, use one of the following solutions.

If the first instance of an item that appears in the data set more than once is deemed a duplicate, the easiest way to go is use Excel's built-in rule for duplicates.

Or, create a conditional formatting rule with this formula:

COUNTIF(*range*, *top_cell*)>1

For example, to highlight duplicates in the range A2:C8, the formula goes as follows:

`=COUNTIF($A$2:$C$8, A2)>1`

Please notice the use of absolute cell references for the range ($A$2:$C$8), and relative references for the top cell (A2).

The solution for this scenario is a lot trickier, no wonder Excel has no built-in rule for it :)

To highlight duplicate entries in several columns ignoring the 1^{st} occurrences, you will have to create 2 rules with the following formulas:

Here you use exactly the same formula as we used to highlight duplicates without 1^{st} occurrences in one column (the detailed steps can be found here).

In this example, we are creating a rule for A2:A8 with this formula:

`=COUNTIF($A$2:$A2,$A2)>1`

As the result, the duplicate items without 1^{st} occurrences are highlighted in the left-most column of the range (there is only one such item in our case):

To highlight duplicates in the remaining columns (B2:C8), use this formula:

`=COUNTIF(A$2:$A$8,B2)+COUNTIF(B$2:B2,B2)>1`

In the above formula, the first COUNTIF function counts the occurrences of a given item in the first column, and the second COUNTIF does the same for all subsequent columns. And then, you add up those numbers and check if the sum is greater than 1.

As the result, all duplicated items excluding their 1^{st} occurrences are found and highlighted:

Another possible solution is to add an empty column to the left of your dataset, and combine the above formulas into a single formula like this:

`=IF(COLUMNS($B2:B2)>1,COUNTIF(A$2:$B$8,B2),0) + COUNTIF(B$2:B2,B2)>1`

Where B2 is the top cell with data in the 2^{nd} column of the target range.

To better understand the formula, let's break it down into 2 main parts:

- For the first column (B), the IF condition is never met, so only the second COUNTIF function is calculated (we have used this formula to find duplicates except first occurrences in one column).
- For all subsequent columns (C2:D8), the key point is the clever use of absolute and relative references in the two COUNTIF functions. To make things easier to understand, I've copied it to column G, so you can see how the formula changes when applied to other cells:

Because the IF condition is always TRUE for all the columns other than the first one (number of columns is greater than 1), the formula proceeds in this way:

- Counts the number of occurrences of a given item (D5 in the screenshot above) in all columns to the left of the given column:
`COUNTIF(B$2:$C$8,D5)`

- Counts the number of a given item's occurrences in the item's column, up to the item's cell:
`COUNTIF(D$2:D5,D5)`

- Finally, the formula adds the results of both COUNTIF functions. If the total number is greater than 1, i.e. if there is more than one occurrence of the item, the rule is applied and the item is highlighted.

If your table contains several columns, you may want to highlight whole rows based on duplicate records in a specific column.

As you already know, Excel's built-in rule for duplicates works only at the cell level. But a custom formula-based rule has no problem with shading rows. The key point is to **select the whole rows**, and then create a rule with one of the following formulas:

- To highlight duplicate rows
**excluding 1**:^{st}occurrences

`=COUNTIF($A$2:$A2, $A2)>1`

- To highlight duplicate rows
**including 1**:^{st}occurrences

`=COUNTIF($A$2:$A$15, $A2)>1`

Where A2 is the first cell and A15 is the last used cell in the column that you want to check for duplicates. As you see, the clever use of absolute and relative cell references is what makes a difference.

The following screenshot demonstrates both rules in action:

The previous example has demonstrated how to color entire rows based on duplicate values in a specific column. But what if you want to view rows that have identical values in several columns? Or, how do you highlight absolute duplicate rows, the ones that have completely equal values in all columns?

For this, employ the COUNTIFS function that allows comparing cells by multiple criteria. For example, to highlight duplicate rows that have identical values in columns A and B, use one of the following formulas:

- To highlight duplicate rows
**except 1**:^{st}occurrences

`=COUNTIFS($A$2:$A2, $A2, $B$2:$B2, $B2)>1`

- To highlight duplicate rows
**with 1**:^{st}occurrences

`=COUNTIFS($A$2:$A$15, $A2, $B$2:$B$15, $B2)>1`

The following screenshot demonstrates the result:

As you understand, the above example is for demonstration purposes only. When highlighting duplicate rows in your real-life sheets, you are naturally not limited to comparing values only in 2 columns, the COUNTIFS function can process up to 127 range/criteria pairs.

Sometimes, you may not need to highlight all duplicates in a column but rather show only consecutive duplicate cells, i.e. the ones that are next to each other. To do this, select the cells with data (not including the column header) and create a conditional formatting rule with one of the following formulas:

- To highlight consecutive duplicates
**without 1**:^{st}occurrences

`=$A1=$A2`

- To highlight consecutive duplicates
**with 1**:^{st}occurrences

`=OR($A1=$A2, $A2=$A3)`

The following screenshot demonstrates highlighting consecutive duplicate texts, but these rules will also work for consecutive duplicate numbers and dates:

If your Excel sheet may have empty rows and you don't want the consecutive blank cells to get highlighted, make the following improvements to the formulas:

- To highlight consecutive duplicate cells
**without 1**and^{st}occurrences**ignore blank cells**:

`=AND($A2<>"", $A1=$A2)`

- To highlight consecutive duplicate cells
**with 1**and^{st}occurrences**ignore blank cells**:

`=AND($A2<>"", OR($A1=$A2, $A2=$A3))`

As you see, it's no big deal to highlight duplicates in Excel using conditional formatting. However, there is even a faster and easier way. To find it out, read the next section of this tutorial.

The Duplicate Remover add-in is the all-in-one solution to deal with duplicate records in Excel. It can find, highlight, select, copy or move duplicated cells or entire duplicate rows.

Despite its name, the add-in can quickly **highlight duplicates in different colors** **without deleting** them.

The Duplicate Remover adds 3 new features to your Excel Ribbon:

*Dedupe Table*- to immediately find and highlight duplicates in one table.*Duplicate Remover*- step-by-step wizard with advanced options to identify and highlight duplicates or unique values in 1 table.*Compare 2 Tables*- find and highlight duplicates by comparing two columns or two separate tables.

After installing Ultimate Suite for Excel, you will find these tools on the *Ablebits Data* tab in the *Dedupe* group:

For this example, I've created the following table with a few hundred rows. And our aim is to highlight duplicate rows that have equal values in all three columns:

Believe it or not, you can get the desired result with just 2 mouse clicks :)

- With any cell in your table selected, click the
**Dedupe Table**button, and the clever add-in will pick up the whole table. - The
*Dedupe Table*dialog window will open with all the columns selected automatically, and the**Color duplicates**option chosen by default. So, all you have to do is click OK :) Done!

And the result would look similar to this:

As you see in the above image, the Dupe Table tool has highlighted duplicate rows **without first instances**.

If you want to highlight duplicates **including first occurrences**, or if you want to color unique records rather than dupes, or if you don't like the default red color, then use the *Duplicate Remover wizard* that has all these features and a lot of more.

Compared to the swift *Dedupe Table* tool, the *Duplicate Remover* wizard requires a few more clicks, but it makes up for this with a number of additional options. Let me show it to you in action:

- Select any cell within your table where you want to highlight duplicates, and click the
**Duplicate Remover**button on the ribbon. The wizard will run and the entire table will get selected. The add-in will also suggest creating a backup copy of your table, just in case. If you don't need it, uncheck that box.Verify that the table has been selected correctly and click

*Next*. - Select one of the following data types that you want to find:
- Duplicates except 1st occurrences
- Duplicates with 1st occurrences
- Unique values
- Unique values and 1st duplicate occurrences

For this example, let's find

*Duplicates + 1st occurrences*:

- Now, select the columns to check for duplicates. Because we want to highlight complete duplicate rows, I've selected all 3 columns.

Additionally, the add-in lets you specify if your table has headers and if you want to skip empty cells. Both options are selected by default.

- Finally, choose the action to perform on duplicates. You have a number of options such as
**selecting**,**deleting**,**copying, moving duplicates**or adding a status column to**identify**the dupes.

Since today we are exploring different ways to **highlight** duplicates in Excel, our choice is obvious :) So, select *Fill with color* and choose one of the standard theme colors, or click *More Colors…* and pick any custom RGB or HSL color.

Click the *Finish* button and enjoy the result :)

This is how you highlight duplicates in Excel using our Duplicate Remover add-in.

## 43 responses to "How to highlight duplicate cells and rows in Excel"

helpfull thank,s you such a great

Dear Madam,

I would like to ask that I have data in Column and i do not want user to enter duplicate value in particular column not just typing method but also cant use cut copy paste command.

How to use conditional formatting to highlight duplicates (either text or number) with different colors

very helpful content, thank you mam, you are doing very excellent job.

i've a problem, plz help to solve this

i've a data in 2 different sheets,i want to highlight the repeated text of a column of sheet2 in a column of sheet1.

The formula's here helped but since I wanted to check for duplicates over multiple columns (without the 1st occurrence), I couldn't do it with your formula.

Although when I tested with it I changed it from: =COUNTIF($A$2:$A2,$A2)>1 into:

=COUNTIF($A$2:A2,A2)>1

And then it was able to check over a wider range than just 1 column.

This does however give it's own problems since it's not working as well as I want it too.

It works fine for most cells except when they're diagonal from each other with the first occurrence in the left column being lower than the one in the right column.

I guess it's easier to show for those that are interested:

https://docs.google.com/spreadsheets/d/1vskEHr5IJzG56Aqqa8E8NNafclE2h7dyYxNaJ1gG5Tc/

My final question would be how to have a perfect solution for this, maybe add another conditional formatting rule that would check from the bottom right to the top left. But this rule would have to be embedded in the first rule or else it will overwrite the "skip 1st occurrence". (it might still do that if it's embedded though, I'm not sure)

Hi Bram,

To highlight duplicates without the 1st occurrence in a range (multiple columns), you can use a formula similar to this:

=(IF(COLUMNS($F20:F20)>1,COUNTIF(E$20:$F$33,F20),0)+COUNTIF(F$20:F20,F20))>1

It's written for the 4th data set in your test sheet, you can check it out there.

Thank you for this solution!

Sadly I don't quite get it yet (for instance, it uses column E in which there is no data) but it works beautifully.

I'll research it in some more depth later on!

I just thought that other users might be looking for a similar solution, so I added an example with more details: How to highlight duplicates in multiple columns

:< This just gives a popup that Excel does not recognize this as a proper forumla for me...

Hi Max,

Most likely, on your computer the List Separator is set to a different character. To check this, please go to Control Panel > Region > Additional Settings, and see what character is set for List Separator. Generally, it's either a comma (my case) or semicolon. If the latter, then simply replace the commas separating the arguments in the formula with semicolons. For more information, please see Excel formulas not working.

THANK YOU

Thanks very useful tips

Highlighting entire rows based on duplicate values in one column - this was exactly what I was looking for, so useful!

Is it possible to make each set of duplicates a different colour? I have the duplicates below, can I make the ones ending in 67H a different colour to the ones ending in 90H?

Computer

1C108749H

1F168937H

1F168967H

1F168967H

1F168978H

1F168990H

1F168990H

If you think by automated function then NO. but it is possible if you apply multiple conditions by following these steps

FIRST CONDITION:

Home>Conditional Formatting>New Rule>Select a Rule Type>Format only cells that contain>Edit the rule description>SPECIFIC TEXT>CONTAINING>67H>FORMAT>CHOOSE YELLOW COLOR

THEN FOR THE SECOND CONDITION

Home>Conditional Formatting>New Rule>Select a Rule Type>Format only cells that contain>Edit the rule description>SPECIFIC TEXT>CONTAINING>90H>FORMAT>CHOOSE RED COLOR

If you have more conditions then repeat the above process with a different colour.

How do you filter out the last record in a duplicate occurrence?

Hi Mark,

You can use Duplicate Remover to find dupes with the first occurrences (described in the article) and then sort the found entries using the standard Excel Sort.

Hi,

Can someone help me....

I have two columns Empid and Amount.

if both the columns Empid and Amount are duplicate I need remove the 1 st occurrence duplicate amount.

Else

if Empid is duplicate and Amount is not duplicate then I want to add the amount

eg

empid Amount Result

12 100 100

12 100

13 120 250

13 130

Thanks in advance

Mat

Hi Mathews,

Not sure if you will ever check back here but for your question, I'd use a formula and not a highlight (or any other conditional formatting).

Imagine your example in Excel, 3 columns, 5 rows.

The formula in C2 would be something like:

=IF($A2=$A1,IF($B2=$B1,"delete this row",$A2+$B2),$A2+$B2)

Now you can just select cell C2 and drag it down.

Later use a search command and search for all instances of "delete this row" (don't forget to set it to values or else it will just select wherever you used that formula).

Oh, it seems I misread a bit of your question.

Your example seems wrong which also confused me (f.e. you mentioned deleting the first double duplicate occurrence but in your example you added the amount behind the first row)

I suggest doing this in 2 parts, first, delete all the rows that you don't want, you could do that with this formula in C2 (and dragging it down):

=IF(A2=A3,IF(B2=B3,"delete this row",""),"")

I removed the rest of my example to just link the sheet I made for you: https://docs.google.com/spreadsheets/d/1AfNzwLHdJa4cX6Vu1Tdm6JSC-MiT51o60qGel9OwdVs/

Hi,

could someone help me?

I have a column with dates just dates that are entered in to it. I would like to know what formula to use to color the cells background green if four or more of the same dates appear. Is there a way to do this?

Hi, I'm trying to use your "highlight all duplicates except the first occurrence" formula.

However, the formatting is working in reverse. It's formatting all instances except the LAST, not the first.

I've tried messing around with it, with no luck.

USED DUPLICATED VALUE EXCEL SHEET 1 AND SHEET 2 SAME NO.

I used your formula: =COUNTIF($A$2:$A2,$A2)>1

in order to highlight duplicates without 1st occurrences.

However, for some reason the formula is highlighting the 1st occurrence of the value instead of the second.

Do you have a solution?

Hi,

When using highlighting duplicate feature or duplicate removing feature on cells with text format, I encounter problem of distinguishing between values in cells with text format. For example, both of these features consider text in cell A2 (0123456)the same as text in cell A7 (123456). Therefore, it will highlight both of them. Is there a way to solve this problem? Thank you.

Hello,

Please create a custom Conditional Formatting rule for range A1:A7 using this formula:

=SUMPRODUCT(--($A$2:$A$7=$A2))>1

Hope it will help you.

Hi There

I have a little different story. I hope you will be able to help with this.

In my spreadsheet, there is a button to transfer data from one sheet (sheet1) to another (sheet2). I want auto highlight duplicates when transfer data from sheet1 to sheet2.

Happy to provide more information if needed and I would greatly appreciate if you can help me with this.

How can I highlight only the second column, but have the formula apply to both columns (so the duplicate from the first column gets highlighted in the second column only).

Hi!

Thanks for the info but I'm having trouble finding unique duplicates.

With this formula if I have for example:

Cell 1. labels

Cell 2. blue labels

It will mark the two as duplicates whereas the content is partially duplicated.

How can I make sure only 100% content is marked as duplicated?

Thank you!

I NEED A SPREADSHEET TO HIGHLIGHT CELL TEXT RED ONCE I HAVE "UL" IN 5 OR MORE CELLS IN A SINGLE ROW. HOW DO I DO THIS?

Hi

I need some help with highlighting cells according to single, duplicate and triplicate occurrences. For example i have a sheet with client IDs entered in a sheet from B3:N368. All IDs occur three times in the sheet against certain dates and times. I was all first entries of the IDs to be highlighted in PINK, all second occurrences in YELLOW and all third occurrences in GREEN. Only the above three colors are required. So, when i scroll down the sheet and see an ID with GREEN cell filling, i know this is the third entry for this ID, and when i scroll up is should find the second occurrence of this ID highlighted in YELLOW. The reason for this requirement is when i look at an ID anywhere on the sheet, i must know whether this is the first, second or third occurrence in the sheet.

Thanks.
