How to Stop Google Docs from Automatically Changing Text to Fractions

The Unwanted Math Formatting

Google Docs is equipped with an auto-formatting engine that attempts to intelligently guess when you are typing mathematical expressions. One of its specific behaviors involves recognizing numbers separated by a forward slash (e.g., “1/2” or “3/4”). When you type these patterns, Docs will often automatically convert the plain text characters into a single, condensed fraction character (½, ¾).

While this looks elegant in a recipe or a formal mathematical paper, it can be incredibly frustrating in professional or technical writing. If you are typing a date format (like “1/2/2024”), referencing a specific version number, or dealing with alphanumeric codes that happen to contain a slash, having the numbers suddenly shrink and combine into a fraction ruins your document’s formatting. You are forced to manually undo the auto-correction every time it happens. To maintain strict control over your text, this automatic conversion should be disabled.

How to Stop Automatic Fraction Formatting

You can turn off this specific text replacement via the Preferences menu.

1. Open a document in Google Docs.
2. Look at the top toolbar and click on Tools.
3. Select Preferences from the dropdown menu.
4. In the Preferences window, click on the Substitutions tab at the top.
5. Scroll down the list of automatic text replacements until you find the specific entries that are converting your text into fractions (such as the rules that convert 1/2 to ½, 1/4 to ¼, etc.).
6. Click the checkboxes next to these offending rules to remove the checkmarks, or click the “X” on the far right to delete the rules entirely.
7. Click the blue OK button to save your changes.

From now on, Google Docs will respect exactly what you type. Your numbers and slashes will remain as separate, plain text characters, giving you complete control over your document’s formatting.
