Index Match Formulas Excel

In Excel, the INDEX and MATCH functions are often used together to look up a value in a table. This combination allows you to search for a value in a specific row or column and retrieve a corresponding value from the intersecting cell. Here’s a basic explanation of how to use INDEX and MATCH:

Assuming you have a table with data, and you want to look up a value based on certain criteria:

INDEX Function:

The INDEX function returns the value of a cell in a specified row and column of a range.

Syntax:

INDEX(array, row_num, [column_num])

array: This is the range of cells that you want to retrieve data from.

row_num: This is the row number from which to retrieve the data.

column_num: (optional) This is the column number from which to retrieve the data. If omitted, only the row is considered.

MATCH Function:

The MATCH function searches for a specified value in a range and returns the relative position of that item.

Syntax:

MATCH(lookup_value, lookup_array, [match_type])

lookup_value: The value you want to search for.

lookup_array: The range of cells containing possible matches.

match_type: (optional) The type of match. Use 0 for an exact match, 1 for less than, and -1 for greater than.

Using INDEX and MATCH together:

You can use the MATCH function to find the position of a specific value in a row or column, and then use that position in the INDEX function to retrieve the corresponding value.

Example:

=INDEX(DataRange, MATCH(LookupValue, LookupColumn, 0), MatchColumn)

DataRange: The entire range of your data (both rows and columns).

LookupValue: The value you want to look up.

LookupColumn: The column where you want to find the LookupValue.

MatchColumn: The column from which you want to retrieve the result.

Here’s a simple example:

Assuming your data is in columns A, B, and C:

A1:A5 contains the lookup values.

B1:B5 contains the criteria to match.

C1:C5 contains the values you want to retrieve.

You can use the following formula in another cell to get the result:

=INDEX(C1:C5, MATCH(LookupValue, B1:B5, 0))

Replace LookupValue with the value you want to search for in column B, and the formula will return the corresponding value from column C.

What is the Index Match Excel

The “Index-Match” combination in Excel refers to using the INDEX and MATCH functions together to perform a lookup and retrieve values from a table. This method is often considered more flexible and robust than using the traditional VLOOKUP function.

Here’s how the Index-Match combination works:

INDEX Function:

The INDEX function returns the value of a cell in a specified row and column of a range.

Syntax:

INDEX(array, row_num, [column_num])

MATCH Function:

The MATCH function searches for a specified value in a range and returns the relative position of that item.

Syntax:

MATCH(lookup_value, lookup_array, [match_type])

Index-Match Combination:

The MATCH function is used to find the position of a value within a lookup range (either a row or a column).

The result of the MATCH function is then used as the row or column number in the INDEX function to retrieve the desired value.

Example:

=INDEX(ReturnRange, MATCH(LookupValue, LookupRange, 0))

LookupValue: The value you want to search for.

LookupRange: The range where you want to find the LookupValue.

ReturnRange: The range from which you want to retrieve the result.

Here’s a step-by-step breakdown:

MATCH Part:

MATCH(LookupValue, LookupRange, 0): Finds the position of LookupValue within LookupRange. The 0 as the third argument ensures an exact match.

INDEX Part:

INDEX(ReturnRange, result_of_MATCH): Uses the result from the MATCH function as the row or column number in the INDEX function to retrieve the corresponding value from ReturnRange.

This combination is particularly useful when dealing with tables where the lookup column might not be the leftmost column, which is a requirement for the VLOOKUP function. The Index-Match combination allows you to look up values in any column and retrieve values from any other column based on the match.

Example Index Match Excel

Sure, let’s go through a simple example of using the INDEX and MATCH functions in Excel.

Suppose you have the following data:

ABC 
 1ProductCategoryPrice
2AppleFruits$1.00
3CarrotVegetable$0.50
4ChickenMeat$3.00
5OrangeFruit$1.20

Now, let’s say you want to find the price of “Carrot” by using the Index-Match combination.

In another cell, you can use the following formula:

=INDEX(C2:C5, MATCH(“Carrot”, A2:A5, 0))

Here’s what each part of the formula does:

MATCH(“Carrot”, A2:A5, 0): This part searches for the position of “Carrot” in the range A2:A5 and returns the relative position. The 0 as the third argument ensures an exact match.

INDEX(C2:C5, result_of_MATCH): This part uses the result from the MATCH function as the row number in the INDEX function to retrieve the corresponding value from the Price column (C2:C5).

So, the result of this formula will be the price of “Carrot,” which is $0.50.

You can replace “Carrot” with any other product name in the MATCH function, and the formula will dynamically find and return the corresponding price from the Price column.

Best uses of Index Match Excel

The combination of INDEX and MATCH in Excel, often referred to as “Index-Match,” is a powerful and flexible way to perform lookups in a table. Here are some of the best uses of Index-Match in Excel:

Non-Leftmost Lookup:

Unlike VLOOKUP, Index-Match allows you to look up values in any column, not just the leftmost column of the table. This flexibility is particularly useful when your lookup values are not in the first column.

=INDEX(ReturnRange, MATCH(LookupValue, LookupRange, 0))

Dynamic Lookups:

Index-Match is excellent for dynamic lookups where the column or row you want to search may change. For instance, if your data structure evolves, you don’t need to update your formulas.

=INDEX(DataRange, MATCH(LookupValue, LookupColumn, 0), MatchColumn)

Two-Dimensional Lookups:

Index-Match is well-suited for two-dimensional lookups. You can search for a value in both rows and columns simultaneously.

=INDEX(ReturnRange, MATCH(LookupRow, RowHeaders, 0), MATCH(LookupColumn, ColumnHeaders, 0))

Avoiding Sorting Limitation:

Unlike VLOOKUP or HLOOKUP, Index-Match doesn’t require the data to be sorted in any particular order. It performs well even with unsorted data.

Handling Errors Gracefully:

Index-Match allows you to handle errors more gracefully using functions like IFERROR. If a match is not found, you can specify a default value or an error message.

=IFERROR(INDEX(ReturnRange, MATCH(LookupValue, LookupRange, 0)), “Not Found”)

Array Formulas:

Index-Match can be used in array formulas to handle multiple matches. This is helpful when dealing with duplicates in the lookup column.

=INDEX(ReturnRange, MATCH(1, (LookupRange=LookupValue)*(CriteriaRange1=Criteria1)*(CriteriaRange2=Criteria2), 0))

By understanding and effectively using the Index-Match combination, you can achieve more sophisticated and flexible lookup operations in Excel, making it a valuable tool for data analysis and reporting.
