The syntax of the IF function is:

=IF(logical_test, value_if_true, value_if_false)

  • logical_test: The condition you want to evaluate.
  • value_if_true: The value returned if the condition is true.
  • value_if_false: The value returned if the condition is false.

2.1.2. Comparing Two Rows For Equality

To compare if two rows are equal, you can use the IF function to compare corresponding cells. For example, if you want to compare row 2 and row 3, you can use the following formula in a new column:

=IF(AND(A2=A3, B2=B3, C2=C3), "Match", "No Match")

This formula checks if the values in columns A, B, and C are the same in both rows.

2.1.3. Identifying Differences

To identify differences, you can modify the IF function:

=IF(A2=A3, "", "Difference in Column A")

This formula will highlight any differences in column A between the two rows.

2.2. Conditional Formatting

Conditional formatting is a powerful tool to visually highlight differences or matches.

2.2.1. Highlighting Matching Rows

To highlight matching rows, follow these steps:

  1. Select the data range.
  2. Go to Conditional Formatting > New Rule.

To compare entire rows using an array formula, you can use the SUM function along with a comparison:

=IF(SUM(--(A2:C2=A3:C3))=COLUMNS(A2:C2), "Match", "No Match")

This formula compares all cells in rows 2 and 3 and returns “Match” if all values are the same.

3.1.3. Detecting Differences With Array Formulas

To detect differences, modify the formula:

=IF(SUM(--(A2:C2A3:C3))>0, "Difference", "No Difference")

This formula checks if there are any differences between the rows.

3.2. Using The MATCH And INDEX Functions

The MATCH and INDEX functions can be combined to perform more complex comparisons.

3.2.1. Understanding MATCH And INDEX

  • MATCH: Returns the position of a value in a range.
  • INDEX: Returns the value at a given position in a range.

3.2.2. Comparing Rows With MATCH And INDEX

You can use MATCH to find if a row exists in another range. For example, to check if row 2 exists in the range of rows 3 to 5, you can use a helper column to concatenate the values and then use MATCH:

  1. In column D, concatenate the values in row 2: =A2&B2&C2.
  2. In column E, concatenate the values in rows 3 to 5: =A3&B3&C3.
  3. Use the MATCH function: =IF(ISNUMBER(MATCH(D2, E3:E5, 0)), "Match", "No Match").

3.2.3. Identifying Matching Data

This approach can identify if an entire row of data matches another row in a specified range.
