How to Disable Red Underlines in PowerPoint on iPad

Product: Microsoft PowerPoint
Device & OS: iPad
Scenario: Editing a presentation on an iPad, particularly in another language, where red spelling and grammar lines appear and persist.
Observed behavior: Persistent red underlines show up under text indicating spelling or grammar errors, and they cannot be removed using standard autocorrection toggles.

Before you start

Ensure your presentation is fully synced and saved to a cloud service like OneDrive or iCloud to prevent any data loss before modifying app settings.

Solution 1

Transfer Content to a New Presentation

Use this method if the persistent red underlines are isolated to a single PowerPoint file, which may indicate file-specific corruption.

Create a new presentation

Open the PowerPoint app on your iPad and tap the plus icon to create a new, blank presentation.

Copy existing slides

Open your original presentation with the red underline issue, select all the slides from the left thumbnail pane, and tap 'Copy'.

Paste and check

Navigate back to the newly created blank presentation, paste the copied slides, and verify if the red underlines have disappeared.

Solution 2Recommended

Reset PowerPoint via iPad Settings

If red underlines appear across all files and toggling autocorrection does not work, resetting the app can resolve deeper application-level glitches.

Frequently Asked Questions

How do I turn off Auto-Correction completely on my iPad?

You can disable auto-correction system-wide by opening your iPad Settings, selecting 'General', then 'Keyboard', and toggling off 'Auto-Correction'. Note that this will affect your typing across all applications, not just PowerPoint.

Why does PowerPoint highlight correctly spelled words in red?

This commonly happens when the text is typed in a different language than the active proofing language set for that text box in PowerPoint. The application attempts to check the spelling against the wrong dictionary.

How do I change the proofing language in PowerPoint for iPad?

Select the text box causing the issue, navigate to the 'Review' tab on the top ribbon, tap the 'Language' icon, and choose the correct language you are currently typing in. This should remove the incorrect red lines.
