Question details
The user wants to calculate the total sum of non-adjacent cells in a spreadsheet using the Excel mobile app on an iPhone.

- Product
- Microsoft Excel
- Device & OS
- iPhone
- Scenario
- Adding up separate, non-contiguous data points or multiple disconnected cell ranges while working on a mobile device.
- Observed behavior
- The user needs the specific formula syntax to accurately select and calculate the sum for scattered cells without accidentally including the unwanted data in between.
Ensure you have the Excel app installed on your iPhone and that your workbook is opened to the sheet containing the numerical data you want to calculate.
Use the SUM Function with Comma-Separated References
The most accurate and efficient way to add non-adjacent cells is by using the SUM function and separating each individual cell or range reference with a comma.
When working on an iPhone screen, manually highlighting multiple non-adjacent cells at once can be tricky due to touch controls. Using the formula bar to type or carefully tap your cell references separated by commas ensures precision and avoids calculation errors.
Tap the empty cell where you want the final sum to appear. Double-tap the cell or tap the formula bar at the top of the screen to activate the on-screen keyboard.
Type =SUM( to begin your calculation function.
Enter the specific cell references separated by commas, such as A1,A3,A5,A7. Alternatively, you can tap the first cell, type a comma in the formula bar, tap the next cell, and repeat until all cells are selected.
Type the closing parenthesis ) so your formula looks like =SUM(A1,A3,A5,A7). Tap the return key on your keyboard or the green checkmark next to the formula bar to execute the calculation.

Frequently Asked Questions
Can I tap cells to select them instead of typing references on my iPhone?
Yes. After typing =SUM(, you can tap a cell on your screen to add it to the formula. To add a non-adjacent cell, you must type a comma in the formula bar first, and then tap the next cell you want to include.
Why am I getting a #VALUE! error when summing non-adjacent cells?
This error typically occurs if one of the referenced cells contains text, hidden spaces, or special characters instead of numbers. Double-check your selected cells to ensure they all contain valid numerical data.
How many non-adjacent cells can I include in the SUM function?
In modern spreadsheet applications, you can include up to 255 individual arguments (which can be single cells or cell ranges) within a single SUM function, providing plenty of flexibility for mobile tasks.
Does this comma-separated SUM method work on iPads and other devices?
Yes, the syntax for the SUM function is identical across all platforms and operating systems. You can use =SUM(A1,B2,C3) whether you are working on an iPhone, iPad, Android device, Windows PC, or Mac.
