Adding the Match type and Completing the MATCH Function
The third and final argument of the MATCH function is the Match_type argument.
This argument tells Excel how to match the Lookup_value with values in the Lookup_array. The choices are: -1, 0, or 1.
This argument is optional. If it is omitted the function uses the default value of 1.
- if the Match_type = 1 or is omitted: MATCH finds the largest value that is less than or equal to the Lookup_value. The Lookup_array data must be sorted in ascending order.
- if the match_type = 0: MATCH finds the first value that is exactly equal to the Lookup_value. The Lookup_array data can be sorted in any order.
- if the Match_type = 1: MATCH finds the smallest value that is greater than or equal to the Lookup_value. The Lookup_array data must be sorted in descending order.

These steps are to be entered after the comma entered in the previous step on the Row_num line in the INDEX function dialog box.
- Following the comma on the Row_num line, type a zero " 0 " since we want the nested function to return exact matches to the terms we enter in cells D3 and E3.
- Type a closing round bracket " ) " to complete the MATCH function.
- Leave the INDEX function dialog box open for the next step in the tutorial.
