In this article, you will learn how to use the Microsoft Excel LAMBDA function and its prime function in Microsoft Excel. You will also get to know the Microsoft Excel LAMBDA function return value and syntax with the help of some examples.

Microsoft Excel LAMBDA Function

The prime usage of the Microsoft Excel LAMBDA function is to provide a way to create custom functions that can be used throughout the workbooks with VBA or macros. So, you can use the LAMBDA function to create a custom function.

Return Value of LAMBDA Function

The return value will be as defined by the formula.

Syntax of LAMBDA Function

=LAMBDA(parameter,.....,calculation)

Where the arguments:

parameter: This is the input value for the function.

calculation: It is the calculation to perform as the result of the function and must be the last argument.

## How to Use Microsoft Excel LAMBDA Function? Now you know the LAMBDA function is used to provide a way to create a custom function in Microsoft Excel. You can use the LAMBDA function anywhere in the workbook once it is defined and named. The LAMBDA function can be very simple or quite complex sometimes, stringing together many formulas at the same time. The custom LAMBDA function doesn't need VBA or macros.

In computer programming, the term LAMBDA alludes to be anonymous function or expression. An anonymous function is a function characterized without a name. In Microsoft Excel, the LAMBDA work is first used to make a generic equation. When a generic equation has been completed and tested, it is ported to the Name Manager, where it is formally defined and named.

One of the critical advantages of a custom LAMBDA function is that the logic contained in the recipe formula is only one spot. This implies there is only one copy of code to update when fixing issues or updating functionality, and changes will naturally proliferate to all occurrences of the LAMBDA function in the workbook.

How to Create a LAMBDA Function?

The LAMBDA function is usually created and debugged in the formula bar in the worksheet, later moved to the name manager to assign a name that can be used anywhere in the workbook. You can create a LAMBDA function using the four basic steps given below:

Verify the logic that you are going to use in the standard formulas.

Create a test for a generic LAMBDA version of the formula.

Name and define the LAMBDA formula in the name manager.

You can also call the new custom function with the defined name.
