You are the boss of ACME Inc. And one day, both of your accountants Sara and James come to you with two versions of the customer payment data. How do you compare these two Excel sheets and reconcile the data? We can use VLOOKUP to do just that. In this article, let me explain the step-by-step process.
Step 1: Set up data in two Excel sheets
Copy both sets of data to two sheets in an Excel file. For example, here I have two sheets – one with Sara’s data and another with James’ data. Both datasets have identical columns, but the data is not same.

Step 2: Start with the first sheet and write the VLOOKUP formula
Go to the first sheet. Here, we are going to use VLOOKUP (or XLOOKUP, if you have Excel 365) to get the matching value from second sheet.
For the purpose of this exercise, you need a unique identifier column like Customer ID or invoice number.
In the adjacent column we are going to write the VLOOKUP function to get the corresponding values for the customer ID’s from second sheet. The set up should look like this:

Step 3: The LOOKUP formula
Write the VLOOKUP formula like this:
=VLOOKUP(B3,'James Sheet'!$B$3:$C$32,2,FALSE)
VLOOKUP Formula Explanation:
- VLOOKUP formula finds matching value from a range. For example, here we can use it to search for the customer ID and get their payment details.
- B3: refers to the cell with customer ID
- ‘James Sheet’!$B$3:$C$32: is the range of data in second Excel sheet which we are trying to match
- 2: is the column number of the “Amount paid” column in second sheet.
- FALSE: ensures that VLOOKUP will look for an exact match in the second sheet.
- Learn more about VLOOKUP function.
Or if you prefer to use XLOOKUP formula, use this:
=XLOOKUP(B3,'James Sheet'!$B$3:$B$32,'James Sheet'!$C$3:$C$32, "ID missing")

Fill this formula down so you can see the matching values from second sheet.
At the end of this step, your first sheet should look like this:
If you have any missing IDs, those cells should have #N/A.

Step 4: Reconcile the values
Now that you have the matching value from second Excel sheet, let’s reconcile both to see which values matched and which values are different.
For this, we can use IF formula. Here is the formula:
=IF(ISERROR(D3),"ID Missing", IF(D3<>C3,"Not matching", "Matching"))

This formula compares the first sheet value with the second sheet value and tells us if they are same or different. It also checks for the #N/A error and flags those records as “Missing ID”.
Fill the formula down and you will have reconciliation information for your data.

Now you can use FILTERS in Excel to see all matching or not matching records easily.
Step 5: Conditional format the non-matching records

This optional step helps us quickly spot all the non-matching and missing ID values quickly.
To do this,
- Select the entire range of data (for example: B3:E32)
- Go to Home ribbon > Conditional Formatting and click on “new rule”
- Select the rule type as “Use a formula to determine the…”
- Type the rule as =$E3 = “Not matching” (refer to the below image)
- Set the formatting to highlight the non-matching records
- Click OK to add the rule.
- Add one more rule for “ID missing” highlight and repeat steps 3 to 6

When you finish, your data will highlight all the non-matching and missing ID values in different color so you can easily identify them.

Other techniques to reconcile and compare two Excel sheets:
While using VLOOKUP is a quick and elegant way to compare two spreadsheets, Excel also offers few more options. These are:
- Power Query: We can use Power Query to compare two sheets or two workbooks of data and reconcile the differences between values. Power Query also makes it easy to compare when you have multiple ID columns (for example: Customer ID & Date as the criteria for comparison). Refer to my Power Query tutorial page for more information on how to combine data with it.
- Using XLOOKUP instead of VLOOKUP: As demoed above, we can use the new XLOOKUP function in Excel to perform the comparison. This allows for built-in error handling so we can see “Missing IDs” easily. Read more about XLOOKUP function here.
- Using Conditional formatting: Excel’s conditional formatting also offers a powerful and simple way to compare two lists of values. See this page for details.
- Using formulas vs. Power Query: I discuss the approaches for comparing two Excel sheets with formulas and PQ in my YouTube video here.
- Using Pivot Tables: Excel Pivot tables can link two tables of data on a key column (like customer ID) so you can easily compare values from both in one view. This feature is called relationships. Learn more about Table Relationships in Excel here.
In conclusion…
Comparing two Excel sheets is an easy task once you know how to use the VLOOKUP (or XLOOKUP) function in Excel. I have used this exact approach countless times when dealing with multiple versions of files or different versions of truth. The process is easy, and the results are actionable.

Hi,
I solved this in a little different way.
We have 2 lists, one starts at A1 and other at B1, both are vertical arrays.
First thing is define 2 named ranges, list1 and list2:
list1 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$A$1:$A$1000""));1)"
list2 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$B$1:$B$1000""));1)"
this way lists will be dynamically sized when you had or remove elements (you can't have blanks and you can't have more than 1000 elements).
Then I use conditional formatting in column A when this formula is true:
"=NOT(ISERROR(MATCH(A1;list2;0)))"
and "=NOT(ISERROR(MATCH(B1;list1;0)))" to list2.
This way we eliminate the need for auxiliary columns or lists.
Hope you like my way! 😀

Simple conditional formatting formula.
Assuming lists vertical lists starting in A1 & B1
To highlight just one column (assume B for example)
Conditional formatting>New Rule>by formula
=MATCH(B1,$A$1:$A$99,0)
Set the cell fill to what ever color you prefer & press OK
To highlight both columns repeat with this formula for cell in column A
=MATCH(A1,$B$1:$B$99,0)
This approach doesn't require named fields or addtl columns

Say I had 1 list in A2:A20 and another in B2:B20.
To format all the items in column A that are repeated in column B I would use the following Conditional Formatting rule.
=IF(ISNA(VLOOKUP(A2,$B$2:$B$20,1,false)),true,false)
All the duplicates are highlighted. It us a very simple example of comparison.
I may be missing something here, but I usually highlight both my lists by holding ctrl eg A1:A20 E10:E40 then choose conditional formatting from the ribbon and then highlight duplicates, and this does it?
Lee, I was perplexed as well. I do the same thing you do with the conditional formating. A drag and click to highlight range and choose highlight duplicates does the trick for me.
I believe these methods are to check if an item from one list also appears in the other list. So if an item mentioned many times in one list if also mentioned in the other list or not.
The Conditional Formatting highlight duplicates feature will do this, but it will also highlight an item if it appears multiple times in the one column or list.
Hi, I would just like to know (if you are willing to share) which image editing program you use to make your image like above, like they are torn apart from bottom? I've been looking for long.

Chandoo is on Holidays, but Chandoo uses Paint.Net
Paint.net is a free download available at http://www.paint.net/
.
I use CorelDraw/PhotoPaint
.
We both use the Snipping Tool (a freebe with Win Vista/10)
.
We both use Camtasia for doing screen captures to make animated GIFs where you see animation.
Here is how I would accomplish
(1) Define Names: List_1, List_2
(2) =ISNA(MATCH(D4,List_2,0))-1 (Conditional Format formula List_1)
(3) =ISNA(MATCH(D4,List_1,0))-1 (Conditional Format formula List_2)
ISNA will return 1 if NO Match and O if Match by adding a -1 will make: NO Match 0 and Match a -1 which is True
Hi all
this my first Post here
i think we can take Unique List for tow list to know what is not Duplicate By this Array formula
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISERROR(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
and this one for Duplicate Value
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISNUMBER(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
Don't forget to Enter This Formula by Pressing Ctrl+Shift+Enter
without wanting to ruthlessly self promote here, I do have an addin that does neatly compare two ranges, not just in columns, so you might want to check that out.
Having said that this is a pretty neat solution if you dont want to be going down the VBA or purchase route. I like it
however, could you not do something with the remove duplicates feature in Excel 2010 and then compare the resulting data set?
Hi, Chandoo! I've found yesterday your Excel website... What can I say? It's just awesome, Excellent. Being a developer for 30 years, more than 15 with Office products, and wow!, how many things I discovered in a couple of hours, and what pretty resolved.
I decided to take the long path of the newbies and read all your examples and write down by myself all of them, and when I arrived to this (the comparison of two lists) I think I've found a problem:
a) in "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)" it should say "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)>0", but this is a typing error that I believe all of us here might have discovered and corrected
b) the very problem: I wrote down two different lists, in different ranges, and with different number of elements, I specified the equivalent conditional formats, et non voilá!, I didn't get what expected. So I downloaded your example book, I checked range names, formulaes, conditional formats and all OK. So I copied -just values- from my book to yours, and I still couldn't achieve the goal.
I'm using Excel 2010 in spanish, I'm from Buenos Aires (Argentina), and my book is at your disposition whenever you considerate it appropiate.
Thanks in advance for your time, and again my congratulations for your work here.
Best regards.

Comparison of 2 lists visually with highlights
Author: SirJB7 / Date: 11-Dic-2011
Pros: no duplicated tables, no matrix formulaes, no named ranges, no VBA code, just conditional formatting
Cons: not found yet, comments and observations welcome
Features:
a) standard problem: highlights in orange/yellow elements existing in the other list
b) optimized problem: idem a) plus highlights in red/violet first occurrence of elements existing in the other list
Sheet contents:
a) conditional format, 1 rule per list (2 methods used)
A1:A20, first list
B1:B20, second list
a1) range A1:A20, condition =NO(ESERROR(BUSCARV(A1;B$1:B$20;1;FALSO))), format Orange ---> in english: =NOT(ISERROR(VLOOKUP(A1,B$1:B$20,1,FALSE)))
a2) range B1:B20, condition =CONTAR.SI(A$1:A$20;B1)>0, format Yellow ---> in english: =COUNTIF(A$1:A$20,B1)>0
b) conditional format, 2 rules per list (2 methods used)
D1:D20, first list
E1:E20, second list
b1) range E1:E20, condition 1 =Y(NO(ESERROR(BUSCARV(D1;E$1:E$20;1;FALSO)));COINCIDIR(D1;D$1:D$20;0)=FILA(D1)), format Red ---> in english: =AND(NOT(ISERROR(VLOOKUP(D1,E$1:E$20,1,FALSE))),MATCH(D1,D$1:D$20,0)=ROW(D1))
same range, condition 2 and format 2, same as a1)
b2) range E1:E20, condition =Y(CONTAR.SI(D$1:D$20;E1)>0;COINCIDIR(E1;E$1:E$20;0)=FILA(E1)), format Violet ---> in english: =AND(COUNTIF(D$1:D$20,E1)>0,MATCH(E1,E$1:E$20,0)=ROW(E1))
same range, condition 2 and format 2, same as a2)
Personally I like the a2) and b2) solutions, I think the formulaes are prettier.
I still don't know the rules of this website and forum, but it any precept is infringed I'm willing to share the workbook with the solution. If it breaks a rule, I apologize and promise that won't happen again.
Best regards for all!
Dear All i have a complicated situation...
1. I have two sheets of data Sheet1 and Sheet2 (from various sources) - Both of these contain data matching and Not matching as well..
2. Now for me i need to build an excel where in i need to get sheet 3 with values that are present in a column of Sheet 1.
What ever Sheet 1 doesn't have i dont want those rows from sheet 2 to be populated into Sheet3.
Can any one help me out.
Hi Team
The above example is to compare partial name from 2 different columns.
If I want to cross check it in a single column. I have both correct and partial correct/match entries in a column. Is there any way I can find both the entries in the column.
Regards
