Match

The MATCH function returns the position of a value in a given range. For example, the MATCH function below looks up the value 53 in the range B3:B9.

Explanation: 53 (first argument) found at position 5 in the range B3:B9 (second argument). In this example, we use the MATCH function to return an exact match so we set the third argument to 0.

Index

The INDEX function below returns a specific value in a one-dimensional range.

Explanation: the INDEX function returns the 5th value (second argument) in the range E3:E9 (first argument).

Index and Match

Replace the value 5 in the INDEX function (see previous example) with the MATCH function (see first example) to lookup the salary of ID 53.

Explanation: the MATCH function returns position 5. The INDEX function needs position 5. It”s a perfect combination. If you like, you can also use the VLOOKUP function. It”s up to you. However, you”ll need INDEX and MATCH to perform advanced lookups, as we will see next.
