# MATCH function

MATCH function allows you to determine the position of the search item in the range of cells. Excel is mainly used as a database to store large amounts of data and frequently, you would have to search the Excel sheet for data. As it is not at all practical to search the data manually, Excel offers a few functions to search the sheet for a specific value like MATCH function. The MATCH function returns the position of the searching value if successful and returns the #N/A error value if the function is unsuccessful. Function syntax is as follows:

MATCH (lookup_value, range_lookup; [match_type])

• Lookup_value is an element we seek. This may be a number, text, logical value or cell reference that contains one of these types of data.
• Range_lookup a range of cells to be searched.
• Match_type is an optional argument (defaults to 1). It decides how to compare the values and looking for cells with the searched range. It may take the following values:

0 - the result is given as the first value in the field of equal sought, 1 - for sorted in ascending column gives the largest value less than or equal sought, -1 - For sorted descending column gives the smallest value greater than or equal sought.

Let us use the function in the following example: To find a person who is X years old, enter the following formula:

= MATCH (X, B2:B18, 0)

Looking for person at age 50, we obtain the result of 9 - and thus the ninth person on the list is 50 years old. Typing an analogous formula for a person who is 60 years old, we get an #N/A error. This means that the value was not found. To use a comparison of 1, sort table columns ascending age. To find the oldest person whose age does not exceed X years, enter the formula:

=MATCH (X, B2:B18, 1)

Since the table is a person aged 50 years, the function returns its position. In the case of finding 60-year-old get the position of being 59 years old. Let's practice with these examples. Open Excel and save your file as match.xlsx. Enter details as in the following image. Example 1: Click the cell F1 and enter the formula =MATCH("MOU",A2:A6,0). Now the result is 2. The item MOU is in the second position in the array. We get the result as 2 because we started the array from A2 and the item is in the cell A3.

Example 2: Click the cell F2 and enter the formula =MATCH("MOU",A1:A6,0). Now the result is 3. The item MOU is in the third position in the array as we started the array from A1 this time.

Example 3: Click the cell F3 and enter the formula =MATCH("Har*",B2:B6, 0). Now the result is 5. Here we use an asterisk to match any sequence of characters.

Example 4: Click the cell F4 and enter the formula =MATCH("Har?",B2:B6, 0).Now your screen will look like this: Here, you get the result as #N/A. The question mark matches a single character and there is no item with a single character after Har and hence it returns #N/A.

Example 5: Click the cell F5 and enter the formula =MATCH("LA?",A2:A6, 0). Now the result is 4. Here we use a question mark to match a single character.

Example 6: Click the cell F6 and enter the formula =MATCH(48,D2:D6, 1). Now the result is 2. Here as the value of type parameter is 1, the position of the largest value that is less than or equal to 48 is returned.

Example 7: Click the cell F7 and enter the formula =MATCH(62,D2:D6). Now the result is 5. Here as the value of type parameter is omitted, it has the default value 1. Hence, the position of the largest value that is less than or equal to 62 is returned.

Example 8: Enter details in the A column as in the following image. Click the cell F8 and enter the formula =MATCH(68,A9:A15,-1). Now the result is 4. Here as the value of type parameter is -1, the position of the smallest value that is greater than 68 is returned.

Example 9: Click the cell F9 and enter the formula =MATCH(43,A9:A15,-1). Now the result is 6. Here as the value of type parameter is -1, the position of the smallest value that is greater than 43 is returned.

Example 10: Click the cell F10 and enter the formula =MATCH(87,A9:A15,0). Now the result is 2. Here as 87 is repeated twice in the array, it returns the position of the first instance of 87.
