Tired of dragging formulas down hundreds of rows in Google Sheets? That’s where ARRAYFORMULA comes to the rescue! It lets you apply a formula to an entire column or range automatically, saving you time and effort. Whether you’re calculating totals, combining text, or applying logical checks, ARRAYFORMULA makes it simple and super efficient — even if you’re new to spreadsheets.
What is the ARRAYFORMULA Function in Google Sheets?
ARRAYFORMULA lets you run a single formula over an entire range of cells instead of copying the same formula down manually. In plain English: one formula, many results!
Why Is It Useful?
ARRAYFORMULA is perfect for anyone who works with large data sets. It saves you from repetitive work, reduces errors, and keeps your sheet dynamic — any new data added to the range will automatically be included.
Real-Life Example: Auto-Calculate Total Sales
Imagine you manage a small online store and track sales like this:
| Item | Units Sold | Price Per Unit | Total Sales |
|---|---|---|---|
| Shirts | 10 | 15 | |
| Hats | 5 | 8 | |
| Shoes | 3 | 50 |
Instead of typing =B2*C2 and dragging it down, you can use this formula in D2:
=ARRAYFORMULA(B2:B4 * C2:C4)
Now, all the Total Sales will auto-calculate at once!
Step-by-Step Instructions: How to Use ARRAYFORMULA
1. Understand the Basic Syntax
ARRAYFORMULA has a simple structure:
=ARRAYFORMULA(expression)
- Expression: This could be a mathematical operation, a text function, or a logical formula that works on ranges.
2. Apply ARRAYFORMULA to a Range
- Click on the cell where you want the results to start.
- Type
=ARRAYFORMULA(followed by your calculation involving ranges (e.g.,B2:B * C2:C). - Close the parentheses and press Enter.
3. Example Formula for Auto-Calculating
=ARRAYFORMULA(B2:B * C2:C)
4. Combine ARRAYFORMULA with IF Statements
You can also combine it with conditions. For example, to leave blank if no data is entered:
=ARRAYFORMULA(IF(B2:B = "", "", B2:B * C2:C))
Key Benefits of Using ARRAYFORMULA
- Saves Time: No need to manually drag formulas down.
- Auto-Updating: New entries are calculated automatically.
- Cleaner Sheets: Fewer formulas cluttering your spreadsheet.
- Reduces Errors: Less chance of missing rows when copying formulas manually.
Pro Tips for Working with ARRAYFORMULA
- Be Mindful of Entire Columns: Using full columns (like
B:B) can slow down very large sheets. Try to limit ranges when possible. - Text Functions: You can use ARRAYFORMULA to combine text, like
=ARRAYFORMULA(A2:A & " sold " & B2:B & " units"). - Logical Checks: Combine with IF and ISBLANK for dynamic calculations that adapt to changes.

ARRAYFORMULA in Google Sheets is a total game-changer for anyone working with repetitive data! Instead of wasting time dragging formulas or worrying about missing rows, you can automate your work with one smart move. Plus, it keeps your spreadsheets clean, dynamic, and error-free. Next time you find yourself copying the same formula over and over, remember: ARRAYFORMULA has your back!
