How can I repair a corrupted powerpoint file?

When a PowerPoint file won't open despite trying "Open and Repair" and Safe Mode, you're in a frustrating spot—but here is an effective free method to try repair a corrupted powerpoint file. Here are the most reliable options, starting with the simplest.

This is widely considered the best free repair technique because it extracts content from the damaged file without fully opening it.

Steps repair a corrupted PowerPoint file:

1. Create a new, blank PowerPoint presentation

2. On the Home tab, click the arrow under New Slide

3. Select Reuse Slides from the dropdown menu

4. In the sidebar that appears, click Browse and locate your corrupted file

5. Select the file—PowerPoint will attempt to read the slides without opening the full presentation

6. Right-click each slide in the sidebar and choose Insert All Slides (or insert them one by one)

7. Save the new presentation

This method often works even when "Open and Repair" fails because it only accesses the slide data rather than the entire file structure.
