14. MATCH Function Returns the relative position of an item in an array that matches a specified value in a specified order Returns the relative position of an item in an array that matches a specified value in a specified order Use MATCH instead of a LOOKUP function Use MATCH instead of a LOOKUP function when you need the position of an item in a range instead of the item itself when you need the position of an item in a range instead of the item itself =MATCH(lookup_value,lookup_array, match_type) =MATCH(lookup_value,lookup_array, match_type)

15. =MATCH Lookup_value Lookup_value The value you want to match in lookup_array The value you want to match in lookup_array Lookup_value can be a value (number, text, or logical value) or a cell reference Lookup_value can be a value (number, text, or logical value) or a cell reference Lookup_array Lookup_array a contiguous range of cells containing possible lookup values a contiguous range of cells containing possible lookup values Lookup_array must be an array or an array reference Lookup_array must be an array or an array reference Match_type Match_type is the number -1, 0, or 1 is the number -1, 0, or 1 Specifies how Excel matches lookup_value with values in lookup_array Specifies how Excel matches lookup_value with values in lookup_array

16. =MATCH If match_type is 1 If match_type is 1 MATCH finds the largest value that is less than or equal to lookup_value MATCH finds the largest value that is less than or equal to lookup_value Lookup_array must be placed in ascending order:...-2, -1, 0, 1, 2,..., A-Z, FALSE, TRUE Lookup_array must be placed in ascending order:...-2, -1, 0, 1, 2,..., A-Z, FALSE, TRUE If match_type is 0 If match_type is 0 MATCH finds the first value that is exactly equal to lookup_value MATCH finds the first value that is exactly equal to lookup_value Lookup_array can be in any order Lookup_array can be in any order If match_type is -1 If match_type is -1 MATCH finds the smallest value that is greater than or equal to lookup_value MATCH finds the smallest value that is greater than or equal to lookup_value Lookup_array must be placed in descending order: TRUE, FALSE, Z-A,...2, 1, 0, -1, -2,..., and so on Lookup_array must be placed in descending order: TRUE, FALSE, Z-A,...2, 1, 0, -1, -2,..., and so on If match_type is omitted, it is assumed to be 1 If match_type is omitted, it is assumed to be 1
