# Using the Nested Function in Excel Microsoft Excel functions are well known for performing basic mathematical operations, complex ones, logical operations, and other types of statistical operations, too. The complexity level of each function depends upon the operation you would like to use and once you become a pro at using them, you can exercise your superiority over the formulas using the concept of nested function in Excel.

## What do you mean by a nested function in Excel?

While using functions, you need to use arguments; otherwise, the function would be void. Now, the same idea is applicable to a nested function, the only difference being that the argument of a nested function will be a function in itself.

Each Excel function has unique coding which was stored in the memory of the Compiler. So, when you apply the concept of nested function, you basically call another stored function as one of your argument and make it a part on which your desired function will work. For example, suppose you want to sum certain contents. If you use the QUOTIENT function as an argument, then the compiler will first call this argumentative function and then evaluate the main SUM function.

## How can you write a nested function Excel?

The syntax of writing a nested function in Excel is:
Cell range= function1(argument 1, function2(argument 2, argument 3), argument 4……)
Here, function2 is the called function whereas function1 is the calling function.
Let’s see an example of how this above syntax will work.
Cell range= SUM(4,QUOTIENT(6,2),7)
=SUM(4,3,7)
=14

## When should you use the nested function Excel?

As nested functions can offer various levels of conjugated formulas, it is basically used when we want to do something repetitive or something related to the application of conditional statements.

1. When you want to check the contents of various cells based on a certain argument, instead of checking each at a time, you can go for nested conditional loops. In most of the cases, the IF, OR and AND functions are used for the conditionals nested functions.
2. When you would like to search a vertical column and print the data in another column of your desire, the nested VLOOKUP functions are better for the job.
3. Nested string functions can also be used in times when you will have to phrase a complex string sentence.

Concluding, it can be said that with the increasing complexity of the operations, you will have to shift over to the nested function Excel in order to avoid the excessive length of the function.
