4. Method 2: Using the Equal Sign Operator for Direct Comparison
The equal sign operator allows you to compare lists cell by cell, returning “TRUE” for matches and “FALSE” for mismatches. This method is straightforward and provides immediate results for each cell comparison. It’s particularly useful for verifying data accuracy row by row.
4.1. Step 1: Insert a New Column
Immediately after the two columns you want to compare, insert a new column. This column will display the results of the comparison.

4.2. Step 2: Put the Formula in Cell C2
In cell C2 (or the first cell in your new column), enter the formula =A2=B2. This formula compares the values in cells A2 and B2.
.webp)
4.3. Step 3: Check the Outcome as “TRUE” or “FALSE”
The formula tests whether the value in cell A2 is equal to the value in cell B2. If the cell values match, the outcome will be “TRUE”; if they do not match, the outcome will be “FALSE.”

Use Case: This method is ideal for comparing data row by row and quickly identifying mismatches.
5. Method 3: Using the VLOOKUP Formula to Find Matches
The VLOOKUP formula is a powerful tool for comparing two lists in Excel, identifying matches or missing values between them. This method is particularly useful when you need to check if values from one list exist in another. It provides a clear indication of whether a match is found or not.
5.1. Step 1: Open Excel and Enter Your Data
Open your MS Excel spreadsheet and enter your lists into the sheet. Ensure your data is organized for easy comparison.
5.2. Step 2: Select a Column for Result
Choose a separate column to display the results of the VLOOKUP formula. This column will indicate whether a match is found or if the value is missing.
5.3. Step 3: Enter VLOOKUP Formula
In the first cell of your results column (e.g., C2), enter the following VLOOKUP formula:
=VLOOKUP(A2,$B$2:$B$9,1,FALSE)How VLOOKUP Works:
- A2: The value from List1 to search for.
- $B$2:$B$9: The column range of List2 to look for the value.
- 1: Specifies that you’re searching within the first column of the range.
- FALSE: Ensures an exact match.
5.4. Step 4: Drag the Formula
Drag the fill handle down the results column to apply the formula to all rows. This will perform the VLOOKUP function for each value in List1.
5.5. Step 5: Preview Results
In the results column, whenever a match is found, the name is displayed. If the value from List1 does not exist in List2, the formula will return #N/A. This clearly indicates missing values.
6. Method 4: Using Row Difference to Highlight Discrepancies
The “Row Difference” method allows you to highlight non-matching cells row by line, quickly identifying any discrepancies between two lists. This technique is useful for data validation and ensuring accuracy in your datasets.
6.1. Step 1: Select the Entire Data Range
To highlight non-matching cells row by line, select the entire data range you want to compare. This ensures that the comparison is applied across all relevant cells.
6.2. Step 2: Open ‘Go to Special’ and Press Special Tab
Press the ‘F5’ key to open the ‘Go to special’ box, then click the “Special” tab. This opens the “Go To Special” dialog box, allowing you to select specific cell types.

6.3. Step 3: Select ‘Row difference’ and Click OK
In the “Go To Special” window, select the “Row differences” option and click on “OK.” This will highlight all cells that differ from their corresponding cells in each row.
.webp)
6.4. Step 4: Preview Results
The highlighted cells indicate where there is a row difference. You can fill these cells with a color to make the differences stand out even more.
7. Method 5: Using IF Condition to Display Matching or Not Matching Results
Using the IF condition allows you to compare rows in Excel and display results as “Coordinating” or “Not Matching,” providing a clear indication of data consistency. This method is particularly helpful when you need to categorize and label the differences between two lists.
7.1. Step 1: Open Excel Spreadsheet
Open your MS Excel and enter the data you want to compare into the sheet. Organize your data for easy comparison.
7.2. Step 2: Use the Formula
In the first cell of your results column (e.g., C2), enter the following formula:
=IF(A2=B2,"Coordinating","Not Matching")This formula compares the values in cells A2 and B2. If they match, it will display “Coordinating”; if they do not match, it will display “Not Matching.”
.webp)
7.3. Step 3: Apply the Formula to Other Rows
Drag the formula down from the corner of the cell to apply it to other rows (e.g., down to cell C9) to compare additional pairs of values. This will automatically populate the results column with “Coordinating” or “Not Matching” based on the cell comparisons.
