How to Stop Excel from Changing Whole Numbers to Decimals on Mac
Question details
Users find that entering a whole number into an Excel cell automatically converts it into a decimal or hundredth (for instance, typing '2' displays as '0.02').

- Product
- Microsoft Excel
- Device & OS
- Mac
- Scenario
- Entering standard whole numbers into spreadsheet cells.
- Observed behavior
- Excel automatically inserts a decimal point, dividing the entered whole number by 100 and shifting it to the hundredths place.
Determine if the problem applies to newly typed numbers across the entire Excel application or if it is restricted to specific pre-formatted cells. This helps identify whether you need to change a global app preference or simply adjust local cell formatting.
Disable Automatic Decimal Insertion in Mac Preferences
Turn off the application-wide setting that automatically inserts a decimal point into all newly typed numbers.
This global preference affects how Excel interprets all numeric entries. Turning it off stops the automatic decimal conversion for new inputs, but it will not revert numbers that have already been converted.
Launch Microsoft Excel on your Mac, click on 'Excel' in the top Apple menu bar, and select 'Preferences'.
In the Preferences dialog window, look under the Authoring section and click on 'Edit'.
Locate and uncheck the box labeled 'Display this number of decimal places'. Close the window to save your changes.

Remove Decimal Formatting from Specific Cells
Use the formatting ribbon to quickly remove unwanted decimal places from existing data visually.
Disable Automatic Decimals on Windows (Alternative)
If you are using Excel on a Windows PC instead of a Mac, the automatic decimal setting is located in the advanced options menu.

Frequently Asked Questions
Why do my numbers stay as decimals after turning off the setting?
Disabling the automatic decimal setting only affects numbers you type after making the change. To fix existing data, you must either type the numbers again or copy a separate cell containing the number 100, use 'Paste Special', and select 'Multiply' over the affected decimal cells.
Can I set a specific number of decimal places for just one column instead of the whole application?
Yes. Instead of changing the global edit preference, you can select the specific column, right-click, and choose 'Format Cells'. Under the Number tab, manually define the exact decimal places required for that column only.
Is there a keyboard shortcut to decrease decimals on Mac?
There is no default single-key shortcut to decrease decimals in Excel for Mac. However, you can add the 'Decrease Decimal' command to your Quick Access Toolbar or use the button directly from the Home tab for faster adjustments.
