When it comes to working with data in Google Sheets, formulas are an essential tool for manipulating and analyzing data. One of the most powerful types of formulas in Google Sheets is the array formula. Array formulas allow you to perform calculations on multiple cells at once, making them incredibly useful for tasks such as summing a range of cells, counting unique values, and more. In this article, we’ll explore the basics of array formulas in Google Sheets, including how to create them, common uses, and troubleshooting tips.
What is an Array Formula?
An array formula is a type of formula in Google Sheets that allows you to perform calculations on multiple cells at once. Unlike regular formulas, which only operate on a single cell, array formulas can operate on a range of cells, making them incredibly powerful for data analysis and manipulation.
Array formulas are denoted by the use of the array constant syntax, which is a range of cells enclosed in curly braces {}. For example, the formula {=A1:A10} would be an array formula that operates on the range of cells A1:A10.
How to Create an Array Formula
To create an array formula in Google Sheets, follow these steps:
- Enter the formula you want to use in the cell where you want the result to appear.
- Press the Ctrl+Shift+Enter keys on your keyboard to enter the array formula.
- Google Sheets will automatically add the curly braces {} around the formula.
For example, to sum the values in a range of cells, you would enter the formula =SUM(A1:A10) and then press Ctrl+Shift+Enter to enter the array formula. The formula will be displayed as {=SUM(A1:A10)}.
Common Uses for Array Formulas
Array formulas are incredibly versatile and can be used for a wide range of tasks, including:
- Summing a range of cells: Use the SUM function to add up a range of cells.
- Counting unique values: Use the COUNTUNIQUE function to count the number of unique values in a range of cells.
- Finding the maximum or minimum value: Use the MAX or MIN function to find the maximum or minimum value in a range of cells.
- Converting text to numbers: Use the VALUE function to convert a range of text cells to numbers.
- Filtering data: Use the FILTER function to filter a range of cells based on a condition.
Array Formula Syntax
Array formulas use a specific syntax to define the range of cells to operate on. The syntax is as follows: (See Also: Google Sheets How to Calculate Percentage? Made Easy)
{=array_function(range)}
Where:
array_function is the function you want to use (e.g. SUM, COUNTUNIQUE, etc.).
range is the range of cells you want to operate on (e.g. A1:A10, B2:C5, etc.).
For example, the formula {=SUM(A1:A10)} would sum the values in the range A1:A10.

| Formula | Description |
|---|---|
| {=SUM(A1:A10)} | Sums the values in the range A1:A10. |
| {=COUNTUNIQUE(B2:B10)} | Counts the number of unique values in the range B2:B10. |
| {=MAX(C2:C10)} | Finds the maximum value in the range C2:C10. |
| {=FILTER(A2:A10, B2:B10 < 10)} | Filters the range A2:A10 to only include values where the corresponding value in the range B2:B10 is less than 10. |
Troubleshooting Array Formulas
Array formulas can be tricky to work with, especially if you’re new to using them. Here are a few common issues to watch out for:
- Array formula not working: Make sure you’ve entered the formula correctly and that the range of cells is correct.
- Array formula returning incorrect results: Check that the formula is operating on the correct range of cells and that there are no errors in the formula.
- Array formula not updating: Make sure the formula is set to update automatically by checking the “Auto-update” box in the formula bar.
Conclusion
Array formulas are a powerful tool in Google Sheets that allow you to perform calculations on multiple cells at once. By following the steps outlined in this article, you should be able to create and use array formulas with ease. Remember to use the curly braces {} to define the range of cells to operate on, and to press Ctrl+Shift+Enter to enter the array formula. With practice, you’ll be able to use array formulas to streamline your workflow and get more done in less time.

FAQs
What is the difference between an array formula and a regular formula?
An array formula is a type of formula that operates on a range of cells, whereas a regular formula only operates on a single cell. Array formulas are denoted by the use of curly braces {} and are entered by pressing Ctrl+Shift+Enter.
Can I use array formulas with other functions?
Yes, array formulas can be used with other functions, such as SUM, COUNTUNIQUE, and MAX. Simply combine the function with the array formula syntax to create a powerful formula.
How do I troubleshoot array formulas?
To troubleshoot array formulas, make sure to check that the formula is entered correctly and that the range of cells is correct. Also, check that the formula is set to update automatically by checking the “Auto-update” box in the formula bar.
Can I use array formulas with dates?
Yes, array formulas can be used with dates. For example, you can use the DATE function to calculate the difference between two dates, or the TODAY function to get the current date.
How do I convert an array formula to a regular formula?
To convert an array formula to a regular formula, simply remove the curly braces {} and enter the formula as a regular formula. For example, the formula {=SUM(A1:A10)} would become =SUM(A1:A10).
