Fix Word Equation Fractions and Superscripts Not Auto-Formatting
Question details
Users are unable to get fractions, superscripts, and subscripts to format automatically when typing mathematical symbols in Word.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Typing mathematical equations and expecting automatic formatting for fractions (/), superscripts (^), and subscripts (_) after pressing the Space bar.
- Observed behavior
- Word stops converting the typed symbols into professional equation formats, even though other standard autocorrections might continue functioning correctly.
Before modifying your settings, verify that you are actively typing inside a designated equation block (Insert > Equation), as mathematical auto-formatting does not apply to standard body text.
Enable Automatic Equation Conversion
Adjust the equation conversion options to ensure mathematical expressions convert to professional formats automatically when you press the Space bar.
If the automatic conversion setting was accidentally disabled, Word will leave your fractions and superscripts exactly as typed. Re-enabling this option restores standard equation behaviors.
Click on your existing equation or insert a new one to display the Equation tab on the top ribbon.
Look for the Conversions group on the Equation ribbon and click the small dialog launcher arrow in the lower-right corner.
In the Equation Options dialog box, check the box that says 'Automatically convert expressions to professional format'.
Click OK to save the changes. Test the fix by typing a fraction (like 1/2) inside an equation block and pressing Space.
Change Equation Input Mode from LaTeX to Unicode
Word's automatic formatting behaves differently if the equation editor is set to LaTeX mode. Switching to Unicode mode restores the default shortcut behaviors.
Run an Online Repair for Microsoft Office
If adjusting the equation settings does not resolve the issue, your Microsoft Office installation may be corrupted and requires a repair.

Frequently Asked Questions
Why do my equations suddenly stop auto-formatting in Word?
This typically occurs if the input mode was accidentally switched to LaTeX or if the 'Automatically convert expressions to professional format' setting was disabled in your Equation Options.
Does Word support LaTeX for typing equations?
Yes, Microsoft Word supports LaTeX input for mathematical equations. However, automatic formatting for shortcuts like fractions and superscripts works differently in LaTeX mode compared to the default Unicode mode.
Will repairing Office delete my documents?
No, running an Online Repair for Microsoft Office only fixes the core program files and resets application configurations. It will not delete or alter your personal documents, files, or saved data.
