The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range. For example, if the range A1:A3 contains the values 5, 25, and 38, then the formula =MATCH(25,A1:A3,0) returns the number 2, because 25 is the second item in the range.
Tip: Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself. For example, you might use the MATCH function to provide a value for the row_num argument of the INDEX function.
Syntax
MATCH(lookup_value, lookup_array, [match_type])
The MATCH function syntax has the following arguments:

lookup_value Required. The value that you want to match in lookup_array. For example, when you look up someone's number in a telephone book, you are using the person's name as the lookup value, but the telephone number is the value you want.
The lookup_value argument can be a value (number, text, or logical value) or a cell reference to a number, text, or logical value. 
lookup_array Required. The range of cells being searched.

match_type Optional. The number 1, 0, or 1. The match_type argument specifies how Excel matches lookup_value with values in lookup_array. The default value for this argument is 1.
The following table describes how the function finds values based on the setting of the match_type argument.
Match_type 
Behavior 
1 or omitted 
MATCH finds the largest value that is less than or equal to lookup_value. The values in the lookup_array argument must be placed in ascending order, for example: ...2, 1, 0, 1, 2, ..., AZ, FALSE, TRUE. 
0 
MATCH finds the first value that is exactly equal to lookup_value. The values in the lookup_array argument can be in any order. 
1 
MATCH finds the smallest value that is greater than or equal tolookup_value. The values in the lookup_array argument must be placed in descending order, for example: TRUE, FALSE, ZA, ...2, 1, 0, 1, 2, ..., and so on. 

MATCH returns the position of the matched value within lookup_array, not the value itself. For example, MATCH("b",{"a","b","c"},0) returns 2, which is the relative position of "b" within the array {"a","b","c"}.

MATCH does not distinguish between uppercase and lowercase letters when matching text values.

If MATCH is unsuccessful in finding a match, it returns the #N/A error value.

If match_type is 0 and lookup_value is a text string, you can use the wildcard characters — the question mark (?) and asterisk (*) — in the lookup_value argument. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.

Formula 
Description 
Result 
=MATCH(39,B2:B5,1) 
Because there is not an exact match, the position of the next lowest value (38) in the range B2:B5 is returned. 
2 
=MATCH(41,B2:B5,0) 
The position of the value 41 in the range B2:B5. 
4 
=MATCH(40,B2:B5,1) 
Returns an error because the values in the range B2:B5 are not in descending order.
