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.
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
-
Assigning and using a single name and value expression:
- Example:
=LET(a, 5, a + 3) - Result:
8
- Example:
-
Assigning and using multiple names and value expressions:
- Example:
=LET(a, 10, b, a * 2, c, a + b, c ^ 2) - Result:
