# Auto populate table from another table using INDEX & MATCH function

In this article, we will learn how to Auto populate table from another table using the INDEX & MATCH function in Excel.
Scenario:

For instance, We need to find the EXACT match from the table without looking it up on the table. We need some fixed formula which helps in finding the exact match as to auto complete table.
How to Solve the Problem?

For the formula to understand first we need to revise a little about the following functions

Now we will make a formula using the above functions. MATCH function will return the index of the lookup value in the row header field. The INDEX function returns the value corresponding to will now be fed into the INDEX function to get the values under the lookup value from the table data.

Generic Formula:

= INDEX ( data , MATCH ( lookup_value, lookup_array, 0 ) , col_num ) )

data : array of values inside the table without headers

lookup_value : value to look for in look_array

look_array : array to look into

match_type : 1 ( exact or next smallest ) or 0 ( exact match) or -1 ( exact or next largest )

col_num : column number, required value to retrieve from the table column.

Example:

The above statements can be complicated to understand. So let’s understand this by using the formula in an example

Here we have a table having details about the world continent. We need to find the country code from the given table from the lookup value as country name.

Incomplete table Lookup_table Here we used the named range instead for cell reference array as it's easy to understand. We are looking up for the value as shown in the snap below.

Use the above formula and named range to get the quantity of the order matching all criteria
Use the formula in the G6 cell:

= INDEX ( table , MATCH ( G4 , list , 0 ) , 2 )

Named ranges

table (A2:B25)

List (A2:A25)

Explanation:

• MATCH function matches the country name India in the list named range and returns its row index to the INDEX function.
• The INDEX function finds the value having ROW index and column number in the table named range
• The formula returns the value from the look_table. The formula returns Country code for the table to complete the table. Now copy the formula using the Ctrl + D or drag down the cell option in excel. As you can see from the above snapshot we obtained all the code details in the table. Auto populate table from another table using the above stated formula.

Here are some observational noter while using the above formula.

Notes:

1. The function returns the #NA error if the lookup array argument to the MATCH function is not of same length of the table array.
2. The formula returns an error if lookup_value doesn't match the value in the table lookup_array.
3. The function matches exact value as the match type argument to the MATCH function is 0.
4. The lookup values can be given as cell reference or directly using quote symbol ( " ) in the formula as arguments.
