Comparing columns in Excel is something that we all do once in a while. Microsoft Excel offers a number of options to compare and match data, but most of them focus on searching in one column. In this tutorial, we will explore several techniques to compare two columns in Excel and find matches and differences between them.
How to compare 2 columns in Excel row-by-row
When you do data analysis in Excel, one of the most frequent tasks is comparing data in each individual row. This task can be done by using the IF function, as demonstrated in the following examples.
Example 1. Compare two columns for matches or differences in the same row
To compare two columns in Excel row-by-row, write a usual IF formula that compares the first two cells. Enter the formula in some other column in the same row, and then copy it down to other cells by dragging the fill handle (a small square in the bottom-right corner of the selected cell). As you do this, the cursor changes to the plus sign:
To find cells within the same row having the same content, A2 and B2 in this example, the formula is as follows: To find cells in the same row with different values, simply replace the equals sign with the non-equality sign (<>): And of course, nothing prevents you from finding both matches and differences with a single formula: Or The result may look similar to this:
As you see, the formula handles numbers, dates, times and text strings equally well. Tip. You can also compare two columns row-by-row using Excel Advanced Filter. Here is an example showing how to filter matches and differences between 2 columns.Formula for matches
=IF(A2=B2,"Match","")
Formula for differences
=IF(A2<>B2,"No match","")
Matches and differences
=IF(A2=B2,"Match","No match")
=IF(A2<>B2,"No match","Match")
Example 2. Compare two lists for case-sensitive matches in the same row
As you have probably noticed, the formulas from the previous example ignore case when comparing text values, as in row 10 in the screenshot above. If you want to find case-sensitive matches between 2 columns in each row, then use the EXACT function:
=IF(EXACT(A2, B2), "Match", "")
To find case-sensitive differences in the same row, enter the corresponding text ("Unique" in this example) in the 3rd argument of the IF function, e.g.:
=IF(EXACT(A2, B2), "Match", "Unique")
Compare multiple columns for matches in the same row
In your Excel worksheets, multiple columns can be compared based on the following criteria:
- Find rows with the same values in all columns (Example 1)
- Find rows with the same values in any 2 columns (Example 2)
Example 1. Find matches in all cells within the same row
If your table has three or more columns and you want to find rows that have the same values in all cells, an IF formula with an AND statement will work a treat:
=IF(AND(A2=B2, A2=C2), "Full match", "")
If your table has a lot of columns, a more elegant solution would be using the COUNTIF function:
=IF(COUNTIF($A2:$E2, $A2)=5, "Full match", "")
Where 5 is the number of columns you are comparing.
Example 2. Find matches in any two cells in the same row
If you are looking for a way to compare columns for any two or more cells with the same values within the same row, use an IF formula with an OR statement:
=IF(OR(A2=B2, B2=C2, A2=C2), "Match", "")
In case there are many columns to compare, your OR statement may grow too big in size. In this case, a better solution would be adding up several COUNTIF functions. The first COUNTIF counts how many columns have the same value as in the 1st column, the second COUNTIF counts how many of the remaining columns are equal to the 2nd column, and so on. If the count is 0, the formula returns "Unique", "Match" otherwise. For example:
=IF(COUNTIF(B2:D2,A2)+COUNTIF(C2:D2,B2)+(C2=D2)=0,"Unique","Match")
How to compare two columns in Excel for matches and differences
Suppose you have 2 lists of data in Excel, and you want to find all values (numbers, dates or text strings) which are in column A but not in column B.
For this, you can embed the COUNTIF($B:$B, $A2)=0 function in IF's logical test and check if it returns zero (no match is found) or any other number (at least 1 match is found).
For instance, the following IF/COUNTIF formula searches across the entire column B for the value in cell A2. If no match is found, the formula returns "No match in B", an empty string otherwise:
=IF(COUNTIF($B:$B, $A2)=0, "No match in B", "")
Tip. If your table has a fixed number of rows, you can specify a certain range (e.g. $B2:$B10) rather than the entire column ($B:$B) for the formula to work faster on large data sets.
The same result can be achieved by using an IF formula with the embedded ISERROR and MATCH functions:
=IF(ISERROR(MATCH($A2,$B$2:$B$10,0)),"No match in B","")
Or, by using the following array formula (remember to press Ctrl + Shift + Enter to enter it correctly):
=IF(SUM(--($B$2:$B$10=$A2))=0, " No match in B", "")
If you want a single formula to identify both matches (duplicates) and differences (unique values), put some text for matches in the empty double quotes ("") in any of the above formulas. For example:
=IF(COUNTIF($B:$B, $A2)=0, "No match in B", "Match in B")
How to compare two lists in Excel and pull matches
Sometimes you may need not only match two columns in two different tables, but also pull matching entries from the lookup table. Microsoft Excel provides a special function for this - the VLOOKUP function. As an alternative, you can use a more powerful and versatile INDEX MATCH formula. The users of Excel 2021 and Excel 365, can accomplish the task with the XLOOKUP function.
For example, the following formulas compare the product names in columns D against the names in column A and pull a corresponding sales figure from column B if a match is found, otherwise the #N/A error is returned.
=VLOOKUP(D2, $A$2:$B$6, 2, FALSE)
=INDEX($B$2:$B$6, MATCH($D2, $A$2:$A$6, 0))
=XLOOKUP(D2, $A$2:$A$6, $B$2:$B$6)
For more information, please see How to compare two columns using VLOOKUP.
If you don't feel very comfortable with formulas, you can have the job done using a fast and intuitive solution - Merge Tables Wizard.
Compare two lists and highlight matches and differences
When you compare columns in Excel, you may want to "visualize" the items that are present in one column but missing in the other. You can shade such cells in any color of your choosing by using the Excel Conditional Formatting feature and the following examples demonstrate the detailed steps.
Example 1. Highlight matches and differences in each row
To compare two columns and Excel and highlight cells in column A that have identical entries in column B in the same row, do the following:
- Select the cells you want to highlight (you can select cells within one column or in several columns if you want to color entire rows).
- Click Conditional formatting > New Rule… > Use a formula to determine which cells to format.
- Create a rule with a simple formula like
=$B2=$A2
(assuming that row 2 is the first row with data, not including the column header). Please double check that you use a relative row reference (without the $ sign) like in the formula above.
To highlight differences between column A and B, create a rule with this formula:
=$B2<>$A2
If you are new to Excel conditional formatting, please see How to create a formula-based conditional formatting rule for step-by-step instructions.
Example 2. Highlight unique entries in each list
Whenever you are comparing two lists in Excel, there are 3 item types that you can highlight:
- Items that are only in the 1st list (unique)
- Items that are only in the 2nd list (unique)
- Items that are in both lists (duplicates) - demonstrated in the next example.
This example demonstrates how to color the items that are only in one list.
Supposing your List 1 is in column A (A2:A6) and List 2 in column C (C2:C5). You create the conditional formatting rules with the following formulas:
Highlight unique values in List 1 (column A):
=COUNTIF($C$2:$C$5, $A2)=0
Highlight unique values in List 2 (column C):
=COUNTIF($A$2:$A$6, $C2)=0
And get the following result:
Example 3. Highlight matches (duplicates) between 2 columns
If you closely followed the previous example, you won't have difficulties adjusting the COUNTIF formulas so that they find the matches rather than differences. All you have to do is to set the count greater than zero:
Highlight matches in List 1 (column A):
=COUNTIF($C$2:$C$5, $A2)>0
Highlight matches in List 2 (column C):
=COUNTIF($A$2:$A$6, $C2)>0
Highlight row differences and matches in multiple columns
When comparing values in several columns row-by-row, the quickest way to highlight matches is creating a conditional formatting rule, and the fastest way to shade differences is embracing the Go To Special feature, as demonstrated in the following examples.
Example 1. Compare multiple columns and highlight row matches
To highlight rows that have identical values in all columns, create a conditional formatting rule based on one of the following formulas:
=AND($A2=$B2, $A2=$C2)
or
=COUNTIF($A2:$C2, $A2)=3
Where A2, B2 and C2 are the top-most cells and 3 is the number of columns to compare.
Of course, neither AND nor COUNTIF formula is limited to comparing only 3 columns, you can use similar formulas to highlight rows with the same values in 4, 5, 6 or more columns.
Example 2. Compare multiple columns and highlight row differences
To quickly highlight cells with different values in each individual row, you can use Excel's Go To Special feature.
- Select the range of cells you want to compare. In this example, I've selected cells A2 to C8.
By default, the top-most cell of the selected range is the active cell, and the cells from the other selected columns in the same row will be compared to that cell. As you can see in the screenshot above, the active cell is white while all other cells of the selected range are highlighted. In this example, the active cell is A2, so the comparison column is column A.
To change the comparison column, use either the Tab key to navigate through selected cells from left to right, or the Enter key to move from top to bottom.
Tip. To select non-adjacent columns, select the first column, press and hold Ctrl, and then select the other columns. The active cell will be in the last column (or in the last block of adjacent columns). To change the comparison column, use the Tab or Enter key as described above.
- On the Home tab, go to Editing group, and click Find & Select > Go To Special… Then select Row differences and click the OK button.
- The cells whose values are different from the comparison cell in each row are colored. If you want to shade the highlighted cells in some color, simply click the Fill Color icon on the ribbon and select the color of your choosing.
How to compare two cells in Excel
In fact, comparing 2 cells is a particular case of comparing two columns in Excel row-by-row except that you don't have to copy the formulas down to other cells in the column.
For example, to compare cells A1 and C1, you can use the following formulas.
For matches:
=IF(A1=C1, "Match", "")
For differences:
=IF(A1<>C1, "Difference", "")

Formula-free way to compare two columns / lists in Excel
Now that you know Excel's offerings for comparing and matching columns, let me show you our own solution for this task. This tool is named Compare Two Tables and it is included in our Ultimate Suite.
The add-in can compare two tables or lists by any number of columns and both identify matches/differences (as we did with formulas) and highlight them (as we did with conditional formatting).
For the purpose of this article, we'll be comparing the following 2 lists to find common values that are present in both.
To compare two lists, here are the steps you need to follow:
- Start with clicking the Compare Tables button on the Ablebits Data tab.
- Select the first column/list and click Next. In terms of the add-in, this is your Table 1.
- Select the second column/list and click Next. In terms of the add-in, it is your Table 2, and it can reside in the same or different worksheet or even in another workbook.
- Choose what kind of data to look for:
- Duplicate values (matches) - the items that exist in both lists.
- Unique values (differences) - the items that are present in list 1, but not in list 2.
Since our aim is to find matches, we select the first option and click Next.
- This is the key step where you select the columns for comparison. In our case, the choice is obvious as we are only comparing 2 columns: 2000 Winners against 2021 Winners. In bigger tables, you can select several column pairs to compare by.
- In the final step, you choose how to deal with the found items and click Finish.
A few different options are available here. For our purposes, these two are most useful:
- Highlight with color - shades matches or differences in the selected color (like Excel conditional formatting does).
- Identify in the Status column - inserts the Status column with the "Duplicate" or "Unique" labels (like IF formulas do).
For this example, I've decided to highlight duplicates in the following color:
And in a moment, got the following result:
With the Status column, the result would look as follows:
Tip. If the lists you are comparing are in different worksheets or workbooks, it might be helpful to view Excel sheets side by side.
This is how you compare columns in Excel for matches (duplicates) and differences (unique values). If you are interested to try this tool, you are welcome to download an evaluation version using the below link.

I have 8 columns. A, B, C, D, E, F, G, H.
I have to find a match if Column A range value matches Column D range and Column B range value matches Column E value. e.g. A1...An = D1..Dn AND B1..Bn = E1..En then True else False.
Thanks,
Mohammad
Hi!
If I understand your task correctly, the following formula should work for you:
=IF((SUM(--(A1=D1:D10)) > 0)*(SUM(--(B1=E1:E10)) > 0),TRUE)
You can learn more about IF function with multiple conditions in Excel in this article on our blog.
Hey Alexander, quick question I have two sheets both have names of students and their ID's. The issue is some names in one sheet are not present in the other so sheet 1 has names sheet 2 doesn't have and vice versa.
Is there a way to maybe compare both data sets and get the differences? There has to be an easier way instead of manually going through each and every name on both sheets seeing the differences.
Hi!
Have you tried the ways described in this blog post? I also recommend this guide: How to compare two Excel files or sheets for differences.
How do I compare the numbers in column A to column B? There are 139 numbers listed in column A and I want to see if any of those numbers are in column B, which has 2399 numbers listed in it. What is the formula to do so?
Hi!
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.
Hi - thank you for the content.
If I have a column containing duplicates and another column containing duplicates and non-duplicates in relation to the first column (but different values) - how do I find entries in the second column that are not duplicated in relation to the first?
Example:
COL1
10491507PN
10504180PR
10600056PK
10637712PW (dup)
10637712PW (dup)
10847773PE
10862215PR
10895567PF
10931675P4
10958992PO
10968118P7 (dup)
10968118P7 (dup)
11383371PV
11392084PW
11650616PO
COL2
Comp
Comp
CompVV
HomeCon (matches dup)
HomeCon (matches dup)
Comp
Comp
Comp
Comp
Comp
TP (does not match dup)
Comp (does not match dup)
HomeCon
HomeCon
CompVV
So in the above example I am aware 10637712PW is a duplicate. I need to also be aware the Col 2 has same values against that duplicate, eg HomeCon.
I am also aware 10968118P7 is a duplicate and need to be aware that Col 2 has two different values against the duplicate, eg. TP and Comp.
Please help?
Hello!
You cannot solve your problem with a single formula. You can find duplicates in column A and then find duplicates in column B. You can also find duplicates in a row, that is, in columns A and B at the same time. Read all the necessary instructions in this article: How to find duplicates in Excel: identify, highlight, count, filter, and more.
I figured out a way to solve this. Add two more columns, and in these, assign a number to all values in your second column, e.g. Comp is 42100 , CompVV is 42200, HomeCon is 42300 etc. You have to have two columns, with the same number in each. And use high values.
Copy all the values from your original first column to a new sheet, remove duplicates, then with a COUNTIF formula count how many are there in your original first column of each. Then with a SUMIFS formula, sum the numbers in your first newly added column if they belong to a given value in your first original column. Then divide the result of these SUMIFS with the results of the COUNTIFS. Then lookup the numbers you get from this in your second added column. If they match, hooray, otherwise, there are different values assigned in your original second column to a value in your original first column.
Hope this makes sense. It was much easier to do it then to explain it.
This would be the end result using your values and my assigned numbers:
10491507PN 1 42100 42100 42100
10504180PR 1 42100 42100 42100
10600056PK 1 42200 42200 42200
10637712PW 2 84600 42300 42300
10847773PE 1 42100 42100 42100
10862215PR 1 42100 42100 42100
10895567PF 1 42100 42100 42100
10931675P4 1 42100 42100 42100
10958992PO 1 42100 42100 42100
10968118P7 2 84900 42450 #N/A
11383371PV 1 42600 42600 42600
11392084PW 1 42600 42600 42600
11650616PO 1 42200 42200 42200
if i have a value in A1 which i need to change to match value which is manually entered along the columns i.e if value is 10 and then 12 is entered into B1 i need A1 to match, and so on if 18 is entered into H1, A1 needs to change to 18
Hi!
I think that your task can only be done with the help of a VBA macro.
Hello,
I have a table with 50 columns and I want to create a new one who will display me if 2 or more values on the row are the same.
Ex:
No. C1 C2 C3 C4 C5 C6 N
10 5 3 20 20 3 21 4
11 7 2 7 3 1 7 3
In my exemple N is the new column and it says to me that 4 ( C3 = C4 so 2 columns, C2 = C5 so another 2 columns, therefor 4 will be display) of the 6 column are matching with atleas one other column.
Thank you !
Hello!
You can find the examples and detailed instructions here: Count duplicates and unique values in a row.
