Click the Home tab in the Excel ribbon.
Click Conditional Formatting in the Styles group.
Select New Rule.
In the New Formatting Rule dialog box, select Use a formula to determine which cells to format.
Enter a formula that compares the selected range with the corresponding range in the second Excel file. For example, if you are comparing cells A1:A10 in the first file with cells A1:A10 in the second file, the formula would be =A1<>Sheet2!A1.
Click Format to choose a formatting style (e.g., fill color) to highlight the differences.
Click OK to apply the conditional formatting rule.

4.2. How To Use Excel Formulas For Data Comparison?

Excel formulas can be used to compare data between two Excel files and identify differences.

Excel formulas offer a flexible way to perform custom comparisons and extract specific information from your data. According to a survey by the Chartered Institute of Management Accountants (CIMA), advanced Excel skills, including formula usage, are highly valued in the finance and accounting professions.

4.2.1. How To Use The EXACT Function?

The EXACT function compares two text strings and returns TRUE if they are exactly the same, including case, and FALSE otherwise.

In a cell where you want to display the comparison result, enter the EXACT function with the two text strings or cell references to compare. For example, =EXACT(A1,Sheet2!A1) compares the text in cell A1 of the current sheet with the text in cell A1 of Sheet2.
Press Enter to see the result. TRUE indicates that the text strings are identical, while FALSE indicates that they are different.
Drag the fill handle (the small square at the bottom-right corner of the cell) down or across to apply the formula to other cells in the range.

4.2.2. How To Use The IF Function With Comparison Operators?

The IF function can be used with comparison operators (e.g., =, <>, >, <) to compare numerical or text values and return different results based on whether the comparison is true or false.

In a cell where you want to display the comparison result, enter the IF function with a comparison operator. For example, =IF(A1=Sheet2!A1,"Match","Mismatch") compares the value in cell A1 of the current sheet with the value in cell A1 of Sheet2. If the values are equal, the formula returns “Match”; otherwise, it returns “Mismatch”.
Press Enter to see the result.
Drag the fill handle down or across to apply the formula to other cells in the range.

5. How To Compare Two Columns In Excel?

Comparing two columns in Excel involves identifying differences, similarities, or matches between the data in those columns, which is essential for data validation, cleaning, and analysis.

Click the Home tab in the Excel ribbon.
Click Conditional Formatting in the Styles group.
Select New Rule.
In the New Formatting Rule dialog box, select Use a formula to determine which cells to format.
Enter a formula that compares the selected column with the second column. For example, if you are comparing column A with column B, the formula would be =A1<>B1.
Click Format to choose a formatting style (e.g., fill color) to highlight the differences.
Click OK to apply the conditional formatting rule.

5.2. How To Use Formulas For Column Comparison?

Excel formulas, such as MATCH, VLOOKUP, and COUNTIF, can be used to compare two columns and identify differences or matches.

Formulas offer a flexible way to perform custom comparisons and extract specific information from your data. A survey by the Chartered Institute of Management Accountants (CIMA) found that advanced Excel skills, including formula usage, are highly valued in the finance and accounting professions.

5.2.1. How To Use The MATCH Function?

The MATCH function searches for a specified item in a range of cells and returns the relative position of that item in the range. It can be used to check if values in one column exist in another column.

In a cell where you want to display the comparison result, enter the MATCH function. For example, =IF(ISNUMBER(MATCH(A1,B:B,0)),"Match","Mismatch") checks if the value in cell A1 exists in column B. If it does, the formula returns “Match”; otherwise, it returns “Mismatch”.
Press Enter to see the result.
Drag the fill handle down to apply the formula to other cells in the column.

5.2.2. How To Use The VLOOKUP Function?

The VLOOKUP function searches for a value in the first column of a range and returns a value in the same row from another column in the range. It can be used to compare data in two columns based on a common identifier.

In a cell where you want to display the comparison result, enter the VLOOKUP function. For example, =IFERROR(VLOOKUP(A1,B:C,2,FALSE),"Mismatch") searches for the value in cell A1 in column B and returns the corresponding value from column C. If the value is not found, the formula returns “Mismatch”.
Press Enter to see the result.
Drag the fill handle down to apply the formula to other cells in the column.

5.2.3. How To Use The COUNTIF Function?

The COUNTIF function counts the number of cells within a range that meet a given criteria. It can be used to determine how many times a value from one column appears in another column.

In a cell where you want to display the comparison result, enter the COUNTIF function. For example, =IF(COUNTIF(B:B,A1)>0,"Match","Mismatch") counts how many times the value in cell A1 appears in column B. If the count is greater than 0, the formula returns “Match”; otherwise, it returns “Mismatch”.
Press Enter to see the result.
Drag the fill handle down to apply the formula to other cells in the column.
