1. Conditional Formatting for Visual Match Highlighting
Conditional Formatting is a user-friendly Excel feature that allows you to automatically format cells based on specific criteria. It’s a visually intuitive way to compare 2 Excel columns for matches and highlight them directly within your spreadsheet.
Step-by-step Guide:
Step 1: Select Your Data Range
Begin by selecting the two columns you want to compare. Click and drag to select all the cells in both columns containing the data you want to analyze.
Step 2: Access Conditional Formatting
Navigate to the “Home” tab on the Excel ribbon. In the “Styles” group, click on “Conditional Formatting.”
Step 3: Highlight Duplicate Values
From the dropdown menu, hover over “Highlight Cells Rules” and then select “Duplicate Values…”
Step 4: Customize Formatting for Matches
A “Duplicate Values” dialog box will appear. Ensure that “Duplicate” is selected in the dropdown. Choose your desired formatting style to highlight the matching values (e.g., Fill with green, Text color red, etc.). Click “OK.”
Excel will instantly highlight all the values that are present in both selected columns, making matches visually prominent.

2. Using the Equals Operator for Simple True/False Checks
The equals operator (=) is a fundamental Excel operator that can be used to directly compare 2 Excel columns for matches on a row-by-row basis. This method provides a simple TRUE or FALSE result, indicating whether the values in corresponding cells are identical.
Step-by-step Guide:
Step 1: Create a Result Column
Insert a new column next to the columns you are comparing. This column will display the results of your comparison. Let’s say you are comparing Column A and Column B, you can create a “Result” column in Column C.
Step 2: Enter the Equals Formula
In the first cell of your result column (e.g., C2), enter the formula =A2=B2. This formula compares the value in cell A2 with the value in cell B2.
Step 3: Apply the Formula to the Entire Column
Drag the fill handle (the small square at the bottom-right corner of the selected cell C2) down to apply the formula to all the rows you want to compare.
Excel will populate the “Result” column with “TRUE” for rows where the values in Column A and Column B match, and “FALSE” where they differ.
Step 4: Customize Results with IF Statements (Optional)
For more descriptive results than TRUE/FALSE, you can incorporate the IF formula. For example, in cell C2, enter =IF(A2=B2, "Match", "No Match").
This will display “Match” when values are identical and “No Match” otherwise, making the results more user-friendly.

3. VLOOKUP Function for Finding Matches and Retrieving Data
The VLOOKUP function is a powerful Excel tool primarily used to search for a value in a column and return a corresponding value from another column in the same row. However, it can also be effectively used to compare 2 Excel columns for matches.
Step-by-step Guide:
Step 1: Create a Result Column
Similar to the equals operator method, create a new column to display the results of the VLOOKUP comparison.
Step 2: Enter the VLOOKUP Formula
In the first cell of the result column (e.g., C2), enter the formula =VLOOKUP(A2, B:B, 1, FALSE). Let’s break down this formula:
A2: This is the value you are looking up (the value from the first column in the current row).B:B: This is the table array, specifying that you are searching in the entire Column B.1: This is the column index number, indicating that you want to return a value from the first column of the table array (which is Column B itself in this case).FALSE: This specifies an exact match.
Step 3: Apply the Formula and Handle Errors
Drag the fill handle down to apply the VLOOKUP formula to all rows.
If a value from Column A is found in Column B, VLOOKUP will return that value. If a value from Column A is not found in Column B, VLOOKUP will return a #N/A error.
To handle errors and display a more user-friendly output, you can use the IFERROR function. Modify the formula in C2 to =IFERROR(VLOOKUP(A2, B:B, 1, FALSE), "No Match").
This revised formula will display the matching value if found, and “No Match” if the value from Column A is not present in Column B.
Step 4: Addressing Partial Matches with Wildcards (Optional)
In scenarios where you need to find partial matches (e.g., “Ford India” in Column A matching “Ford” in Column B), you can use wildcards with VLOOKUP. Modify the formula to =IFERROR(VLOOKUP(A2&"*", B:B, 1, FALSE), "No Match"). Adding &"*" after A2 tells VLOOKUP to look for values in Column B that start with the value in A2. Note: Wildcards can impact performance with very large datasets.
Apply this modified formula to your result column to identify partial matches.
4. IF Formula for Custom “Match” or “Different” Results
The IF formula offers a flexible way to compare 2 Excel columns for matches and display custom text-based results based on whether a match is found or not.
Step-by-step Guide:
Step 1: Create a Result Column
Add a new column to display your custom “Match” or “Different” results.
Step 2: Enter the IF Formula
In the first cell of your result column (e.g., D2), enter the formula =IF(A2=B2, "Same", "Different"). This formula checks if the value in A2 is equal to the value in B2. If TRUE, it returns “Same”; if FALSE, it returns “Different”.
Step 3: Apply the Formula
Drag the fill handle down to apply the IF formula to all relevant rows. The result column will now clearly indicate “Same” for matching rows and “Different” for non-matching rows.
5. EXACT Formula for Case-Sensitive Column Comparison
The EXACT formula is specifically designed for comparing 2 Excel columns for matches with case sensitivity. Unlike the equals operator and IF formula used previously, EXACT distinguishes between uppercase and lowercase letters.
Step-by-step Guide:
Step 1: Create a Result Column
Insert a new column to display the TRUE/FALSE results of the EXACT formula.
Step 2: Enter the EXACT Formula
In the first cell of your result column (e.g., C2), enter the formula =EXACT(A2, B2).
Step 3: Apply the Formula
Apply the formula to the entire column using the fill handle. The result column will display “TRUE” only when the values in both columns are exactly the same, including case, and “FALSE” otherwise.

Choosing the Right Method for Your Scenario
The best method to compare 2 Excel columns for matches depends on your specific needs and the complexity of your data comparison task. Here’s a guide to help you choose:
Scenario 1: Row-by-Row Comparison for Simple Matches
For straightforward row-by-row comparison to see if values in two columns are identical, use:
=IF(A2=B2, "Match", " ")or=IF(A2=B2, "Match", "No Match")for general comparison.=IF(EXACT(A2, B2), "Match", " ")for case-sensitive comparison.
Scenario 2: Comparing Multiple Columns for Row Matches
To check for matches across more than two columns in the same row:
=IF(AND(A2=B2, A2=C2), "Complete Match", " ")for checking if all columns match.=IF(COUNTIF($A2:$E2, $A2)=4, "Complete Match", " ")(adjust column range and count as needed).=IF(OR(A2=B2, B2=C2, A2=C2), "Match", "")for checking if at least two columns match.
Scenario 3: Finding Unique Values (Differences) Between Two Columns
To identify values present in one column but not in another:
=IF(COUNTIF($B:$B, $A2)=0, "Not in Column B", "")to find values in Column A that are not in Column B.=IF(ISERROR(MATCH($A2,$B$2:$B$10,0)), "Not in Column B", "")(adjust range as needed).=IF(COUNTIF($B:$B, $A2)=0, "Not in Column B", "Present in Column B")for a combined result of matches and differences.
Scenario 4: Comparing Lists and Extracting Matching Data
To compare two lists and retrieve matching data from one list based on matches in another, use:
VLOOKUP:=VLOOKUP(D2, $A$2:$B$6, 2, FALSE)(adjust lookup value, table range, and column index).INDEX MATCH:=INDEX($B$2:$B$6, MATCH($D2, $A$2:$A$6, 0))(more flexible alternative to VLOOKUP).XLOOKUP:=XLOOKUP(D2, $A$2:$A$6, $B$2:$B$6)(modern and improved lookup function, if available in your Excel version).
Scenario 5: Highlighting Row Matches and Differences Visually
For visual identification of row matches and differences:
- Use Conditional Formatting with formulas:
=AND($A2=$B2, $A2=$C2)to highlight rows where all specified columns match.=COUNTIF($A2:$C2, $A2)=3(adjust column range and count).
- Utilize Excel’s “Go To Special” feature:
- Select the data range.
- Go to “Home” > “Find & Select” > “Go To Special.”
- Choose “Row Differences” and click “OK.”
- Apply formatting (e.g., fill color) to highlight differences.
