LETformula allows you to create variables in a formula and define their value before using them. This can make complex formulas easier to read and maintain by breaking them into smaller parts. It is most commonly used in combination with other formulas to simplify complex formulas.

LETformula not working?
- Similar formulas to
LET formula with the syntax shown below, it has 3 required parameters and 2 optional parameters:
- name1 (required):
The name of the first variable to create.
- value_expression1 (required):
The expression that defines the value of the first variable.
- name2 (optional):
The name of any additional variables to create.
- value_expression2 (optional):
The expression that defines the value of any additional variables.
- formula_expression (required):
The formula expression that uses the previously defined variables.
ExamplesHere are a few example use cases that explain how to use the
LETformula in Google Sheets.
Simplifying complex formulas
By breaking a complex formula into smaller parts using
LET, you can make it easier to read and maintain.
Reducing formula errors
LET to define variables can reduce the likelihood of formula errors by making it easier to keep track of each part of a complex formula.
You can use
LET to nest formulas inside each other, creating a hierarchy of variables and formulas that can be easier to understand and debug.
LETnot working? Here are some common mistakes people make when using the
LETGoogle Sheets Formula:
Not using the correct syntax
Make sure you follow the correct syntax for
LET when defining variables and using them in your formula.
Forgetting to close parentheses or quotes
Make sure you close all parentheses and quotes in your formula, as leaving them open can cause errors.
Using the wrong variable name
Double-check that you are using the correct variable name in your formula expression.
The following functions are similar to
LET or are often used with it in a formula:
IFformula is a logical function used to test a condition and return one value if the condition is true and another value if the condition is false. It is commonly used to create conditional statements and perform calculations based on certain conditions.
ANDfunction in Google Sheets is a logical function that returns TRUE if all of the logical expressions in the argument are TRUE, and FALSE if any of the logical expressions are FALSE. It can be used to test multiple conditions and evaluate whether they are all true or not.
ORformula is a logical formula that returns TRUE if at least one of the provided logical expressions is TRUE. It returns FALSE if all logical expressions are FALSE. This formula is commonly used in conjunction with other logical formulas, such as
AND, to build more complex logical statements.
SUMfunction in Google Sheets adds up a range of numbers. This function is most commonly used to sum the values in a range of cells.
The AVERAGE function calculates the average (arithmetic mean) of the values passed to it. It is commonly used to find the average of a range of cells containing numerical data.
