The Excel INDEX function returns the value at a given position in a range or array. You can use index to retrieve individual values or entire rows and columns. INDEX is often used with the MATCH function, where MATCH locates and feeds a position to INDEX. The value at a given location.
The difference is illustrated below. The other key difference is that INDEX MATCH formulas work as a right to left lookup, whereas VLOOKUP only works left to right. As you can see in the example below, I can use INDEX MATCH to lookup a value that is to the right of my return value using INDEX MATCH.When we combine both the INDEX formula and the MATCH formula, the number that the MATCH formula returns becomes the row number for your INDEX formula. =INDEX (array, MATCH formula). Below is an example of using the INDEX MATCH to return âProduct Typeâ for our lookup value.As you can see, it returns the same value we got from VLOOKUP.INDEX (array, row number). Below is an example of using INDEX to return the value âShirts,â assuming that you already know that the value is three cells down on your defined array. (you also have the option to specify column number, but that isnât relevant in a basic INDEX MATCH formula).
