Mastering ARRAYFORMULA: 4 use cases with examples

ARRAYFORMULA are valuable tools for managing spreadsheets, making it easier to handle complex calculations and automate repetitive tasks. Whether you’re processing sales data, formatting dates, or applying conditional logic, ARRAYFORMULA can streamline your Workflows. This blog’ll explore four practical use cases to help you unlock their potential.

1. Advanced calculations in reports

Scenario: A sales team must apply a 10% discount across multiple products. Manually doing this for each row is time-consuming, but an array formula can simplify the process.

A B C
Product Sales ($) Discounted Sales ($) (Using Array Formula)
Product A 100 ARRAYFORMULA(B5:B7 * 0.9)
Product B 200 180
Product C 300 270

Copy this spreadsheet to check out the formula

How it works:

The array formula automatically multiplies each value in the sales column by 0.9 (10% discount), applying the calculation across the entire range.

Benefits:

  • Save time by processing multiple rows in a single step.
  • Reduce errors caused by manual calculations.

2. Extracting insights from dates

Scenario: You need to display the month and year for a set of dates in your report. Instead of converting each date manually, you can use an array formula.

A B
Date Month-Year (Using Array Formula)
01/01/2024 ARRAYFORMULA(TEXT(A5:A11, “MMMM YYYY”))
15/02/2024 January 2024
25/03/2024 February 2024

Copy this spreadsheet to check out the formula

How it works:

The TEXT function, combined with an array formula, formats dates into readable month-year formats automatically.

Benefits:

  • Quickly transform dates for better readability.
  • Prepare datasets for grouped reports or dashboards.

3. Dynamic range referencing

Scenario: Calculate total expenses for items costing more than $100. Instead of manually filtering the data, an array formula dynamically applies the criteria.

A B C
Item Cost ($) Expenses ($)
Chair 120 ARRAYFORMULA(SUMIF(B5:B7, “>100”, B5:B7))
Table 150 270
Lamp 90

Copy this spreadsheet to check out the formula

How it works:

The array formula uses SUMIF to check costs exceeding $100 and sums the corresponding rows.

Benefits:

  • Automate criteria-based calculations.
  • Ensure real-time updates when data changes.

4. Transforming data for automation

Scenario: Classify students’ scores as “Pass” or “Fail” based on a threshold of 50. An array formula makes it easy to apply this logic across the dataset.

A

C

Student

Result (Using Array Formula)

Alex

80

ARRAYFORMULA(IF(B5:B7 > 50, “Pass”, “Fail”))

Jamie

45

Fail

Sam

90

Pass

Copy this spreadsheet to check out the formula

How it works:

The formula evaluates each score, returning “Pass” for scores above 50 and “Fail” for those below the threshold.

Benefits:

  • Apply consistent logic to large datasets.
  • Minimize manual classification errors.
