Welcome to the ultimate guide on using the LAMBDA function in Google Sheets. If you’re a fan of Excel, you’re in luck because the usage of the LAMBDA function is pretty much the same in both applications. In this post, we’ll dive into the standalone use of the LAMBDA function and explore its various applications. So, let’s get started and unlock the full potential of this amazing tool!
The Power of Standalone LAMBDA Function in Google Sheets
The LAMBDA function in Google Sheets can be used standalone or in conjunction with a few handy helper functions known as LHFs (Lambda helper functions). These LHFs include MAP, REDUCE, BYROW, BYCOL, SCAN, and MAKEARRAY. By mastering the standalone use of the LAMBDA function, you’ll be well-equipped to leverage its full potential and understand the benefits of the associated helper functions even better.
Syntax and Arguments of the Standalone LAMBDA Function
Let’s familiarize ourselves with the syntax and arguments of the standalone LAMBDA function in Google Sheets. Don’t worry, it’s simpler than it sounds!
Syntax: =LAMBDA([name, …],formula_expression)(function_call, …)
Arguments:
-
name: An optional identifier to pass a value(s) to the function. You can use multiple names by separating them with commas. The name(s) must be valid, avoiding cell references like “A1” or “B1.” Special characters are not supported except for dots and underscores, and the name must not start with numbers.
-
formula_expression: The formula that you want to calculate or execute. This argument is required.
-
function_call: Use this to input actual value(s) based on your formula_expression. If no name argument is needed, simply use (). This helps customize the function to your specific needs.
It’s worth mentioning that the syntax provided here may differ slightly from the official documentation. I’ve modified it slightly to ensure a clearer understanding.
Examples of the LAMBDA Function in Action
Now, let’s dive into some practical examples to understand how the LAMBDA function works and why it’s such a powerful tool.
Examples Without the Optional ‘Name’ Argument
In some cases, you may not need to pass any value to the formula_expression. Here are a couple of examples:
Example 1 (Non-Array Formula):
To return a heart character in any applied cell, you can use the following formula:
=char(129505)
We can also achieve the same result using the LAMBDA function as follows:
=lambda(char(129505))()
Example 2 (Array Formula):
If you want to return the serial/sequential numbers 1 to 10 in the B1:B10 range, you can use the following formula:
=arrayformula(row(A1:A10))
With the LAMBDA function, you can achieve the same result using:
=lambda(arrayformula(row(A1:A10)))()
Examples Utilizing All Arguments
Now, let’s explore examples that utilize all the arguments of the LAMBDA function:
Example 3 (Non-Array Formula):
To return the heart symbol n times, you can use the following formula:
=rept(char(129505),A1)
Using the LAMBDA function, the formula would be:
=lambda(n_times,rept(char(129505),n_times))(A1)
Example 4 (Array Formula):
To flip data in a column or range, you can use the SORT function in Google Sheets. Here’s an example:
=SORT(A2:B,ROW(A2:A)*N(A2:A<>””),0)
To achieve the same result using the LAMBDA function, you can use:
=lambda(flip_range, first_col_range, SORT(flip_range,ROW(first_col_range)*N(first_col_range<>””),0))(A2:B,A2:A)
Common Errors and How to Avoid Them
While using the LAMBDA function, you may encounter a few common errors. Here’s a quick overview to help you troubleshoot:
-
N/A: This error occurs when you have the wrong number of arguments in use. Make sure to include the function_call with the actual values.
-
NAME?: If you use an invalid identifier in the first argument or use a wrong function name in the formula_expression, you may encounter this error.
-
REF!: Circular dependency can lead to this error. Be cautious when setting up your formulas to avoid circular references.
