LET

Assigns name with the value_expression results and returns the result of the formula_expression. The formula_expression can use the names defined in the scope of the LET function. The value_expressions are evaluated only once in the LET function even if the following value_expressions or the formula_expression use them multiple times.

LogicalLET(name1, value_expression1, [name2, …], [value_expression2, …], formula_expression )

LET

The LET function in Google Sheets assigns names with the corresponding value expressions and returns the result of the formula expression. It allows you to define and use variables within a formula, making it easier to write and understand complex calculations. Explore our detailed guide to learn how to effectively utilize the LET function.

Function Syntax and Parameters

Syntax: LET(name1, value_expression1, [name2, …], [value_expression2, …], formula_expression)

Parameters:

  • name1: The name to assign the first value expression to.
  • value_expression1: The value expression to assign to the first name.
  • name2, …: [Optional] Additional names to assign corresponding value expressions to.
  • value_expression2, …: [Optional] Additional value expressions to assign to corresponding names.
  • formula_expression: The expression that uses the assigned names and returns the desired result.

Step-by-Step Tutorial

  1. Assigning and using a single name and value expression:

    • Example: =LET(a, 5, a + 3)
    • Result: 8

  2. Assigning and using multiple names and value expressions:

    • Example: =LET(a, 10, b, a * 2, c, a + b, c ^ 2)
    • Result: 144

Use Cases and Scenarios

  1. Complex Calculations: Simplify lengthy formulas by assigning intermediate results to variables.
  2. Scenario Analysis: Evaluate different scenarios by assigning different values to variables.
  3. Formula Clarity: Improve readability of complex formulas by assigning descriptive names to intermediate values.
