When it comes to data analysis and manipulation in Google Sheets, one of the most powerful and versatile formulas is the ArrayFormula. This formula allows you to perform calculations on arrays of cells, which can be a game-changer for anyone who works with large datasets. In this blog post, we’ll explore the ins and outs of the ArrayFormula, including how to use it, its limitations, and some best practices for getting the most out of this powerful tool.
What is the ArrayFormula?
The ArrayFormula is a Google Sheets formula that allows you to perform calculations on arrays of cells. An array is a range of cells that can be thought of as a single unit, and the ArrayFormula can be used to perform calculations on this array as a whole, rather than individual cells within the array.
The syntax for the ArrayFormula is simple: =ARRAYFORMULA(array_expression). The array_expression is the range of cells that you want to perform the calculation on, and the formula will return an array of results, one for each cell in the range.
How to Use the ArrayFormula
To use the ArrayFormula, you’ll need to follow these steps:
- Enter the ArrayFormula syntax: =ARRAYFORMULA(array_expression)
- Replace array_expression with the range of cells that you want to perform the calculation on
- Press Enter to calculate the formula
For example, let’s say you have a range of cells A1:A10 that contains a list of numbers, and you want to calculate the average of these numbers. You can use the ArrayFormula as follows:
=ARRAYFORMULA(AVERAGE(A1:A10))
This formula will return an array of results, one for each cell in the range A1:A10. The result will be the average of the numbers in each cell. (See Also: How Do You Insert a Calendar into Google Sheets? Easily Done Today)
ArrayFormula vs. Regular Formula
One of the key benefits of the ArrayFormula is that it can be used to perform calculations on entire ranges of cells, rather than individual cells. This can be especially useful when working with large datasets, where it can be time-consuming to enter a formula for each individual cell.
For example, let’s say you have a range of cells A1:A10 that contains a list of numbers, and you want to calculate the sum of these numbers. You can use a regular formula as follows:
=SUM(A1:A10)
This formula will return a single result, which is the sum of the numbers in the range A1:A10. However, if you want to calculate the sum of a range of cells that spans multiple rows or columns, you’ll need to use the ArrayFormula.
=ARRAYFORMULA(SUM(A1:A10))
This formula will return an array of results, one for each cell in the range A1:A10. The result will be the sum of the numbers in each cell.
ArrayFormula Limitations
While the ArrayFormula is a powerful tool, it’s not without its limitations. Here are a few things to keep in mind:
- The ArrayFormula can only be used with arrays of cells that are contiguous (i.e., they are next to each other)
- The ArrayFormula cannot be used with arrays of cells that are non-contiguous (i.e., they are not next to each other)
- The ArrayFormula cannot be used with arrays of cells that are located in different worksheets or workbooks
- The ArrayFormula can only be used with formulas that are supported by Google Sheets

- Use the ArrayFormula to perform calculations on entire ranges of cells, rather than individual cells
- Use the ArrayFormula to perform calculations on arrays of cells that are contiguous
- Use the ArrayFormula to perform calculations on arrays of cells that are located in the same worksheet or workbook
- Use the ArrayFormula with formulas that are supported by Google Sheets
- Use the ArrayFormula to perform calculations on arrays of cells that are large enough to require the use of the formula
Common Use Cases for the ArrayFormula
The ArrayFormula can be used in a wide range of situations, including:
- Calculating the average of a range of cells
- Calculating the sum of a range of cells
- Calculating the count of a range of cells
- Calculating the maximum or minimum value of a range of cells
- Performing calculations on arrays of cells that are located in different worksheets or workbooks
