Formula generator for LAMBDA function

The LAMBDA function in Excel allows you to create and return a custom function with a set of names and a formula_expression that uses them. To calculate the formula_expression, you can call the returned function with as many values as the name declares.

How to generate an LAMBDA formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To obtain the LAMBDA formula for your specific data, you can ask the AI chatbot the following question: "Is there a way to simplify or optimize my Excel formula to perform calculations on my data more efficiently?"

LAMBDA formula syntax

The LAMBDA function in Excel allows you to create your own custom formulas. Here is a clear and concise overview of the LAMBDA syntax: 1. Start by typing "=LAMBDA(" in a cell or formula bar. 2. Specify the parameters for your custom formula by entering the parameter names, separated by commas. For example, if your formula takes two parameters, you can use "x, y" as the parameter names. 3. After specifying the parameters, use a comma to separate them from the formula expression. The formula expression is the calculation or operation you want to perform using the parameters. 4. Close the LAMBDA function with a closing parenthesis ")". Here's an example of a LAMBDA function that adds two numbers: =LAMBDA(x, y, x + y) In this example, "x" and "y" are the parameters, and "x + y" is the formula expression that adds the two parameters together. Once you define a LAMBDA function, you can use it just like any other formula in Excel by referencing the cell containing the LAMBDA function and providing the required parameter values. Note that LAMBDA functions are only available in the latest versions of Excel, such as Microsoft 365 and Excel 2021.

Use Cases & Examples

In these use cases, we use the LAMBDA formula to create custom functions in Excel. With LAMBDA, you can define your own formulas by specifying the input parameters and the desired calculation. This allows you to perform complex calculations or automate repetitive tasks more efficiently.

Calculate the area of a circle


This use case calculates the area of a circle using the LAMBDA function. The formula_expression is defined as 'PI() * name^2', where 'name' represents the radius of the circle.


=LAMBDA(radius, PI() * radius^2)

Calculate the total cost of a product


This use case calculates the total cost of a product by multiplying the price per unit with the quantity. The formula_expression is defined as 'name * quantity', where 'name' represents the price per unit and 'quantity' represents the quantity of the product.


=LAMBDA(price_per_unit, quantity, price_per_unit * quantity)

Calculate the average of a range


This use case calculates the average of a range of values using the LAMBDA function. The formula_expression is defined as 'SUM(name) / COUNT(name)', where 'name' represents the range of values.


=LAMBDA(range, SUM(range) / COUNT(range))
