If you’re a Google Sheets user, you probably know that it lacks the built-in capability to dynamically spill an array formula result down or across, unlike its rival, Excel. But fear not! There is a dedicated function in Google Sheets called ARRAYFORMULA that can help you achieve a similar effect. In this article, we’ll dive deep into the ARRAYFORMULA function, explore its syntax and usage, and uncover some of its hidden gems.
ARRAYFORMULA Function: Syntax and Arguments
Before we get into the nitty-gritty details, let’s familiarize ourselves with the syntax of the ARRAYFORMULA function in Google Sheets:
ARRAYFORMULA(array_formula)
As you can see, this function has only one argument: array_formula. This argument can take various forms, such as a range of cells, a mathematical expression, or even a function that returns a result greater than a single cell. The possibilities are endless!
Now, let’s take a closer look at a few examples to help you understand the versatility of the ARRAYFORMULA function.
Example 1: Range of Cells
Suppose you want to calculate the amount of each product by multiplying the values in columns C and D. Instead of manually entering the formula in each cell, you can simply use the ARRAYFORMULA function in cell E3 like this:
=ARRAYFORMULA(C3:C7*D3:D7)
Example 2: Mathematical Expression
Let’s say you want to extract the first two characters from a range of text values in cells A2 to A10. You can achieve this with the following ARRAYFORMULA:
=ARRAYFORMULA(LEFT(A2:A10, 2))
Example 3: Function Returning a Result Greater than a Single Cell
If you’re looking to find month-end dates from a range of dates in column B1 to B1000, you can use the ARRAYFORMULA function along with the EOMONTH function like this:
=ARRAYFORMULA(TO_DATE(IFERROR(EOMONTH(DATEVALUE(B1:B1000), 0))))
These are just a few basic examples to get you started. The ARRAYFORMULA function opens up a world of possibilities for you to explore!
5 Things to Keep in Mind When Using Array Formulas
Now that you’re armed with the ARRAYFORMULA function, here are five key points to keep in mind when using array formulas in Google Sheets:
1. Ensure Sufficient Blank Cells for Expansion
Make sure that the array formula has enough blank cells to expand to. If there aren’t enough blank cells, you may encounter a #REF! error.
2. Use Open Ranges Wisely
When using open ranges, place the formula in the first row (for vertical data) or column (for horizontal data) of the range to ensure correct expansion. Placing the formula in any row below the first row or any column to the right of the first column may cause errors and affect performance.
3. Understand the Functionality of ARRAYFORMULA
Not all uses of the ARRAYFORMULA function are meant to return array results. It can also be used to expand the result of another function, such as the YEAR function or logical functions like AND.
4. Be Aware of Unsupported Functions
Some functions are not supported by the ARRAYFORMULA function in Google Sheets. For non-criteria-based functions that accept a range argument and return a single result (e.g., SUM, MAX, ISDATE), the array formula may not be able to expand it. However, criteria-based functions that accept a range argument and multiple criteria can be expanded.
5. Explore Other Functions with Automatic Expansion
Certain functions, such as SEQUENCE, INDEX, QUERY, FILTER, SORT, IMPORTRANGE, VSTACK, HSTACK, and others, can automatically expand to neighboring cells without the use of the ARRAYFORMULA function. These functions can be handy in specific scenarios.
Benefits of Using ARRAYFORMULA in Google Sheets
Now that you know the ins and outs of ARRAYFORMULA, let’s explore its main benefits:
- Improved Spreadsheet Performance: Array formulas can replace thousands of non-array formulas, improving spreadsheet performance.
- Ease of Formula Corrections: Editing an array formula is as simple as modifying it in a single cell.
- Error Elimination: Array formulas automatically fill empty cells caused by modifications in the sheet layout, reducing the risk of formula errors.
- Efficient Data Cleaning: Removing old formulas from your sheet becomes a breeze with array formulas, saving you time and effort.
Harnessing the Power of ARRAYFORMULA with Other Functions
ARRAYFORMULA can be combined with various other functions to unleash its full potential. Here are a few examples to get you started:
- Utilize VLOOKUP and XLOOKUP to search and retrieve data efficiently.
- Count instances with COUNTIF and SUMIF to analyze data effectively.
What LAMBDA Can Do That ARRAYFORMULA Can’t
While ARRAYFORMULA is a powerful tool, there are some scenarios where it falls short. For example, it cannot expand the MIN function. However, you can leverage the LAMBDA function to achieve the desired expansion.
Conclusion
Now that you’ve learned about the ARRAYFORMULA function and its capabilities, you can take your Google Sheets skills to the next level. Array formulas enable you to streamline your workflows, improve performance, and eliminate errors. Remember to keep your sheet tidy and follow our tips when using open ranges.
