**6 Suitable Approaches to Find Duplicates in Two Columns in Excel**

**1. Finding Duplicates within Similar Rows in Two Columns**

In the 1st section, weâ€™ll find out the duplicates within the same rows only in two columns. But these methods are not applicable for case-sensitive matches. If you need to find exact matches with considering letter cases right now, then we have a solution for this too in method 5.

**1.1 Using Equal Sign as Logical Argument to Detect Duplicates within Similar Rows in Two Columns**

We have two lists of names in **Columns B & C**. And we can find duplicates within the same row by simply using the equal sign as a logical function.

**ðŸ“Œ**** Steps:**

âž¤ Select **Cell D5** & type:

`=B5=C5`

âž¤ Press **Enter**, youâ€™ll get the 1st return value. If matches are found, the value will return as **TRUE** & if not found, it will return as **FALSE**.

âž¤ Now use **Fill Handle **to autofill the rest of the cells in **Column D** to find all matches.

**1.2 Using IF Function to Find Duplicates within Same Rows in Two Columns**

By using the logical function-** IF**, you can find & show the duplicates in another column.

**ðŸ“Œ**** Steps:**

âž¤ In **Cell D5**, the formula will be:

`=IF(B5=C5,B5,"")`

âž¤ Press **Enter**.

âž¤ Use **Fill Handle** to autofill other cells in **Column D **& youâ€™re done.

**1.3 Applying Conditional Formatting to Highlight Matches within Same Rows in Two Columns**

If you want to find duplicates within the same rows in two columns then probably conditional formatting suits best to highlight the matches and it wonâ€™t let you type any function to search for matches.

**ðŸ“Œ**** Step 1:**

âž¤ Select the whole range of cells that is considered for finding duplicates.

**ðŸ“Œ**** Step 2:**

âž¤ Under the **Home** tab, from the drop-down of **Conditional Formatting** in the **Styles** group of commands, select the **New Rule** command. A dialogue box will appear.

**ðŸ“Œ**** Step 3:**

âž¤ Now select the rule type to use a formula to determine within cells to format.

âž¤ In the **Rule Description** editor, type **=$B5=$C5**

âž¤ Select **Format** option & another dialogue box will appear.

**ðŸ“Œ**** Step 4:**

âž¤ From the **Fill** tab, select a color that you want to use for highlighting the duplicates.

âž¤ Press **OK** & youâ€™ll be shown the Sample format with selected color in the **New Formatting Rule** dialogue box.

**ðŸ“Œ**** Step 5:**

âž¤ Press **OK** for the last time & youâ€™re done.

In the picture below, the matches in the same rows are now visible with the selected color.

**2. Finding Duplicates within Any Rows in Two Columns**

**2.1 Applying Conditional Formatting to Locate All Duplicates in Two Columns**

To find duplicates in two columns in any rows, you can directly use the related command in **Conditional Formatting** for highlighting.

**ðŸ“Œ**** Step 1:**

âž¤ Select the range of cells first.

**ðŸ“Œ**** Step 2:**

âž¤ Under the **Home **tab & from the **Conditional Formatting** drop-down, select **Duplicate Values** from the **Highlight Cells Rules**. A dialogue box will appear.

**ðŸ“Œ**** Step 3:**

âž¤ Select the color you want to show for highlighting the duplicates.

âž¤ Press **OK** & youâ€™re done.

Like the picture below, youâ€™ll see all the matches with the selected & highlighted colors.

**2.2 Combining IF & COUNTIF Functions to Detect Duplicates in Two Columns**

We can use** IF & COUNTIF** functions together to find data from the 1st column in the 2nd column for matches.

**ðŸ“Œ**** Steps:**

âž¤ In **Cell D5**, we have to type the following formula:

`=IF(COUNTIF($C$5:$C$15,$B5)=0,"",$B5)`

âž¤ Press** Enter **& then use **Fill Handle** to autofill the rest of the cells in **Column D**. Thus youâ€™ll get all the names from List 1 that are present in List 2.

**2.3 Using IF, AND, COUNTIF Functions to Find Specific Duplicate in Two Columns**

Now if you want to type a name & see if that is present in both columns then this method is the best suited. In **Cell F8**, the name â€˜Kyleâ€™ has been written & if the name is present in both **Columns B & C**, then the output will show the message- **YES**, otherwise itâ€™ll return as **NO**.

**ðŸ“Œ**** Steps:**

âž¤ The related formula in **Cell F9** will be:

`=IF(AND(COUNTIF(B5:B15,F8),COUNTIF(C5:C15,F8)),"YES","NO")`

âž¤ Press **Enter** & youâ€™ll see itâ€™s showing **YES**, so the name â€˜Kyleâ€™ is present in both **Columns B & C**.

**2.4 Combining IF, ISERROR. MATCH Functions to Find Matches in Two Columns**

If you want to use the **MATCH** function to find matches or duplicates in two columns within any rows, then you have to insert **ISERROR **within **IF & MATCH** functions otherwise if a match/duplicate is not found youâ€™ll be shown an Error message.

**ðŸ“Œ**** Steps:**

âž¤ In **Cell D5**. the formula with **MATCH **function will be:

`=IF(ISERROR(MATCH($B5,$C$5:$C$15,0)),"",$B5)`

âž¤ Press **Enter**, autofill the entire column by using** Fill Handle** & youâ€™ll find the results at once.

**3. Finding Duplicates in More Than Two Columns**

**3.1 Using IF-AND Functions to Find Duplicates within Same Rows in More Than Two Columns**

To find matches or duplicates in more than two columns, we have to use **AND** function to add multiple logics. So, in our modified dataset, now we have another column (List 3) with more names & weâ€™ll find all the matches within the same rows in **Column E**.

**ðŸ“Œ**** Steps:**

âž¤ In **Cell E5**, the formula based on the criteria will be:

`=IF(AND(B5=C5,C5=D5),B5,"")`

âž¤ Press **Enter**, autofill the rest of the cells with **Fill Handle** & youâ€™ll get all the matches in the same rows right away.

**3.2 Using IF-OR Functions to Find Duplicates within Similar Rows in Any Two of Multiple Columns**

Now hereâ€™s another case where weâ€™ll find the duplicates in any of the two columns within the same rows from more than two columns and if the matches are found then the message will show â€˜Foundâ€™, otherwise itâ€™ll return as a blank.

**ðŸ“Œ**** Steps:**

âž¤ We have to type in **Cell E5**:

`=IF(OR(B5=C5,C5=D5,D5=B5),"Found","")`

âž¤ Press **Enter**, autofill the rest of the cells in the column & youâ€™ll get all the matches found within the same rows.

**4. Extracting Data Based on Duplicates in Two Columns**

**4.1 Using VLOOKUP or INDEX-MATCH to Extract Data Based on Duplicates in Two Columns**

Based on the duplicates found in two columns, we can also pull out data with **VLOOKUP **or **INDEX-MATCH **formulas. In our modified dataset, **Columns B & C** represent the names of some people with the amounts of their donations. In **Column E,** a few names are present & weâ€™ll find the donations of those few people in **Column F** by finding duplicates in two **Columns- B & E**.

**ðŸ“Œ**** Steps:**

âž¤ In **Cell F5**, the related formula with **VLOOKUP** will be:

`=VLOOKUP(E5,$B$5:$C$15,2,FALSE)`

âž¤ Press** Enter**, autofill the entire column & youâ€™ll get the donation amounts of those selected people from **Column E**.

You can also use the** INDEX-MATCH** formula here to find similar results. In this case, the formula in **Cell F5 **will be:

`=INDEX($B$5:$C$15, MATCH($I5,$B$5:$B$15,0),2)`

Then press **Enter**, autofill the entire column & youâ€™re done.

**4.2 Inserting Wildcard Characters inside VLOOKUP or INDEX-MATCH Functions to Extract Data Based Partial Matches in Two Columns**

Now we have full names in** Column B** & with short names in **Column E**, weâ€™ll search for the partial matches in **Column B** & then extract the donation amounts of the selected people in **Column F**. We have to use **Wildcard Characters (Asterisk-â€™*â€™) **here before & after the cell references from **Column E** as **Asterisk(*)** will search for the additional texts.

**ðŸ“Œ**** Steps:**

âž¤ The related formula in **Cell F5** will be:

`=VLOOKUP("*"&E5&"*",$B$5:$C$15,2,FALSE)`

âž¤ Press **Enter**, autofill the entire column & youâ€™ll find the results at once.

And if you opt to use **INDEX-MATCH** functions, then you have to type in **Cell F5**:

`=INDEX($B$5:$C$15, MATCH("*"&$I5&"*",$B$5:$B$15,0),2)`

Then press** Enter **& use the **Fill Handle** to fill down the entire column.

**5. Finding Case-Sensitive Duplicates in Two Columns**

All methods mentioned above were case-insensitive. Now if you want to find duplicates in two columns in the same rows with case Case-Sensitive on, then this section will show you the way. Here, in two columns of List 1 & 2, some names are present in both columns but not with similar case letters. With the **EXACT** function, weâ€™ll find out which names are the same with considering the case-sensitive on.

**ðŸ“Œ**** Steps:**

âž¤Â In **Cell D5**, the formula will be:

`=EXACT(B5,C5)`

âž¤ Press **Enter**, autofill the rest of the cells by using **Fill Down **& youâ€™ll get all the exact matches with case sensitive on. The matches will be shown as **TRUE**, and the mismatched result will return as **FALSE **logical value.

**6. Using VBA Editor to Find Duplicates in Two Columns**

If you love to code with **VBA Editor** for Excel functions, then this method might be suitable for you. We are going to show the duplicates in **Column D** with the help of **VBScript**.

**ðŸ“Œ**** Step 1:**

âž¤ Press **Alt+F11** to open the **VBA** window.

âž¤ From the **Insert** tab, select **Module**. A new module for the VBA editor will appear where youâ€™ll type the codes.

**ðŸ“Œ**** Step 2:**

âž¤ In the editor window, copy the following codes:

```
Sub Duplicates()
Dim List2 As Variant
Dim data1 As Variant
Dim data2 As Variant
Set List2 = Range("C5:C15")
For Each data1 In Selection
For Each data2 In List2
If data1 = data2 Then data2.Offset(0, 1) = data1
Next data2
Next data1
End Sub
```

âž¤ Click on the** Run** button or press **F5 **to activate the subroutine.

**ðŸ“Œ**** Step 3:**

âž¤ Close the VBA window or press **Alt+F11** again to return to the Excel workbook.

âž¤ Now select the range of cells from List 1 that need to be inspected for matches in List 2.

**ðŸ“Œ**** Step 4:**

âž¤ From the **Developer** tab, select **Macros**, a dialogue box will open.

**Note:** If you donâ€™t find the **Developer **option at the top or ribbon section, then you have to enable it by opening **Excel Options** first. There youâ€™ll find the **â€˜Customize Ribbonâ€™ **option. From the **Main Tabs** option, put a Select mark on **Developer**. Press **OK** & the Developer tab should now appear at the top of your Excel workbook.

**ðŸ“Œ**** Step 5:**

âž¤ As you have already activated the macro, so now this macro name will be visible in the dialogue box. Press **Run **& youâ€™re done with your steps.

Youâ€™ll find all the matches in column D like in the picture below.
