Fix PowerPoint Subscript Applying Superscript Formatting Issue
Question details
The user needs to fix a formatting bug in PowerPoint where selecting the Subscript option incorrectly formats the text as Superscript.

- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Formatting text within a presentation slide using the font settings ribbon.
- Observed behavior
- The Subscript command applies superscript formatting, while the Superscript command functions normally. The issue persists even after updating the software, running Safe Mode, and disabling proofing corrections.
Ensure you have saved all your open documents and closed all Microsoft Office applications to prevent data loss before running a system repair.
Perform an Online Repair for Microsoft Office
Running an Online Repair replaces corrupted application files and fixes deep-rooted software bugs that standard updates or Safe Mode cannot resolve.
Since the issue persists in Safe Mode and across updates, the core PowerPoint application files handling text formatting are likely corrupted. The Microsoft Office Online Repair tool performs a comprehensive fix by reinstalling clean versions of these files.
Click the Windows Start menu and select Settings, then navigate to the Apps section and click on Installed apps or Apps & features.
Scroll through the list of installed applications until you find your version of Microsoft Office or Microsoft 365.
Click on the three dots next to the Microsoft Office application and select Modify from the dropdown menu. If prompted by User Account Control, click Yes.
In the repair dialog box, select the Online Repair option instead of Quick Repair, then click Repair to begin the process. This may take several minutes and requires an active internet connection.
Once the repair process finishes, restart your computer. Open PowerPoint, select some text, and click the Subscript command to verify it works correctly.

Frequently Asked Questions
Why didn't Safe Mode fix the subscript formatting issue in PowerPoint?
Safe Mode only temporarily disables add-ins, extensions, and customizations. If the bug is caused by corrupted core installation files, Safe Mode will not resolve the issue, and a complete software repair is necessary.
Will running an Online Repair delete my PowerPoint files?
No, running a Microsoft Office Online Repair only replaces missing or corrupted application system files. It does not delete, move, or modify any of your personal presentations or documents.
What is the keyboard shortcut for subscript in PowerPoint?
You can typically apply subscript in PowerPoint by highlighting the text and pressing the Ctrl and Equal sign (=) keys simultaneously.
What is the difference between Quick Repair and Online Repair?
Quick Repair runs offline and attempts to fix minor issues quickly by checking local files. Online Repair takes longer because it connects to Microsoft servers to download and completely replace all software files, making it much more effective for persistent bugs.
