To fully comprehend Index Match, it’s essential to dissect its core elements: the INDEX and MATCH functions. Each brings distinctive qualities, optimizing Excel’s data lookup capabilities when paired together.

Understanding the INDEX Function

The INDEX function in Excel acts as a map, guiding us to a specific cell within a particular range based on row and column numbers.

Let’s examine this more closely with an example:

find the exact value of a cell using the index function

Imagine a range of cells (A1:C10). You want to find the value located at the intersection of the 3rd row and 2nd column within this range. Using the INDEX function like this: =INDEX(A1:C9, 3, 2) will lead you precisely to the value residing in cell B3.

Understanding the MATCH Function

The MATCH function operates like a search engine within Excel, scanning through a designated range for a specified item, and returning that item’s relative position. The function is formatted as “=MATCH(lookup_value, lookup_array, [match_type])“.

Here’s a simplistic breakdown:

  • Lookup Value: It’s the specific item you’re searching for within a range.
  • Lookup Array: It’s the range where Excel will look for the item.
  • Match Type: How you want to search, allowing for exact or approximate matches.

That’s all it takes to construct the MATCH function. Next up, let’s take a look at the options available when running this formula, particularly when it comes to Match Type.

Match Type

Match type options in excel

This parameter is pivotal. It sets the tone for the search, determining if you want an exact match, or if you’re open to approximate matches. Here are the options:

0 (Exact Match): Excel will only return a position if it finds an exact match. If not, it returns an error. =MATCH(“Apple”, A1:A5, 0) – This will look for the exact word “Apple” in the range A1:A5.

1 (Less Than): Excel seeks the largest value that’s less than or equal to the lookup value. For this to work seamlessly, the lookup array should be in ascending order. =MATCH(5, {1,3,5,7,9}, 1) – If you’re searching for a value like 4, it will match with 3, the largest value less than 4.

-1 (Greater Than): Excel aims to find the smallest value that’s greater than or equal to the lookup value. Here, the lookup array must be in descending order. =MATCH(5, {9,7,5,3,1}, -1) – Searching for a value like 4 with this setup will match with 5, the smallest value greater than 4.

With its straightforward format and customizable parameters—lookup value, lookup array, and match type, the MATCH Function offers a tailored searching process, enhancing the ease and accuracy of data retrieval in Excel.

Match Function Example: Finding Product Code

Let’s say you have a column of product codes (A1:A11) and you want to find the position of a specific code, “PRD05”.

find the position of a specific code with the math function

In a column filled with product codes (A1:A11), you want to find the position of a specific code, “PRD05”. Utilizing the MATCH function like this: =MATCH(“PRD05”, A1:A11, 0). The formula will probe the range and return the position where “PRD05” is found, considering it’s looking for an exact match due to the third argument being zero.

Combining INDEX and MATCH

In combination the INDEX and MATCH functions form an exceptional tool for executing advanced lookups. When utilized together they can extract data from a matrix with unmatched flexibility and accuracy, outperforming traditional lookup functions in efficiency and adaptability.

Why Combine INDEX and MATCH?

When united, the INDEX and MATCH functions amplify Excel’s lookup abilities. Combining INDEX and MATCH offers a versatile solution to find a lookup value within a table range, utilizing the row and column numbers.

Creating an INDEX MATCH formula involves integrating the MATCH function as an argument within the INDEX function. Here’s an example of how to craft the formula correctly:

INDEX MATCH Example: Find the price of product in a table

Suppose you want to find the price of a specific product in a table. You have product names in column A and their corresponding prices in column B.

Begin by using the MATCH function to find the row number of the product. =MATCH(“ProductName”, A2:A6, 0) This formula returns the row number where “ProductName” is located within the range.

use the match function to find the row number of the product

Now, you nest the MATCH function inside the INDEX function to find the price from column B. =INDEX(B2:B6, MATCH(“ProductName”, A2:A6, 0)) This combined formula precisely fetches the price of the specified product from the table.

use the combined INDEX MATCH formula to find the price of the product

The INDEX MATCH formula is versatile, allowing for the retrieval of values within the same column through relative referencing. It can also be expanded to incorporate a lookup table, ensuring accurate identification of the desired column position.

INDEX MATCH vs VLOOKUP Function
