How to Fix PowerPoint Spell Check Only Checking Master Slides
Question details
The user is experiencing an issue where PowerPoint's spell check feature is skipping newly added text and only reviewing predefined content on slide masters.

- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Running a spell check on a new presentation that was generated from a customized PowerPoint template.
- Observed behavior
- The spell check function successfully scans predefined text on the slide masters but completely ignores any new content added to standard presentation slides.
Ensure you have saved a backup copy of your current presentation and template before altering any master slide configurations or language proofing settings.
Test for Template-Specific Behavior
Create a new, simple test template to determine if the spell checking issue is isolated to your current template or if it is a broader PowerPoint bug.
Often, complex templates can develop corrupted placeholder configurations that prevent the spell checker from recognizing new text fields. Isolating the issue to a specific template is the first step in troubleshooting.
Open PowerPoint and start a completely new, blank presentation without applying your custom template.
Add some test text with intentional misspellings to both the slide master and the standard slides. Save this file as a PowerPoint Template (.potx).
Open the newly created test template to generate a new presentation, and add more intentionally misspelled words to the new slides.
Go to the 'Review' tab and run the spell check. If the new misspelled words are detected, your original template is likely corrupted and needs to be rebuilt.

Verify Proofing Language Exceptions
Check if the text placeholders on your slides have been explicitly set to bypass the spell checker.

Frequently Asked Questions
Why does PowerPoint spell check skip certain text boxes?
This usually happens because the specific text box or placeholder has the 'Do not check spelling or grammar' property enabled. You can fix this by highlighting the text, navigating to Review > Language > Set Proofing Language, and unchecking that option.
How do I find my PowerPoint version for troubleshooting?
To locate your specific version and build number, open PowerPoint, click on the 'File' menu in the top-left corner, and select 'Account'. Your product information and version number will be displayed on the right side.
Can a corrupted slide master affect the spell checker?
Yes, if a presentation is created from a corrupted template (.potx), the spell check engine may fail to map the inherited placeholders correctly, resulting in newly added text being ignored during a spelling scan.
