How to Fix PowerPoint Linked Excel Files and Update Link Errors
Question details
Users experience broken links, security warnings, or software crashes when attempting to update PowerPoint presentations that contain linked Excel charts or tables.

- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Updating a PowerPoint presentation that relies on external linked Excel data.
- Observed behavior
- The presentation displays a security warning, fails to locate the original Excel source file, or crashes during the link update process.
Verify that the original Excel file has not been deleted, renamed, or moved to a different folder, as missing source files are the primary cause of broken links.
Reconnect the Excel Workbook via Edit Links
Manually update the file path to restore the connection between your PowerPoint presentation and the external Excel data.
When you move or rename the source Excel workbook, PowerPoint can no longer find the data to update your linked charts or tables. Using the Edit Links tool allows you to point the presentation to the correct file location.
Open your PowerPoint presentation. Navigate to the 'File' menu, select 'Info', and click on 'Edit Links to Files' located in the bottom right corner.
In the Links dialog box, review the list of linked files to identify the Excel workbook with the broken connection or incorrect file path.
Select the broken link, click the 'Change Source' (or 'Edit Source') button, navigate to the current location of your Excel file, select it, and confirm to re-establish the connection.

Update PowerPoint to Resolve Crash Issues
If PowerPoint crashes specifically when updating links, installing the latest Office updates can resolve known software bugs.

Frequently Asked Questions
Why does PowerPoint show a security warning for linked Excel files?
PowerPoint displays this warning to protect your computer from potentially malicious external data. If you trust the source Excel file and created it yourself, it is safe to allow the links to update.
What causes Excel links in PowerPoint to break?
Links typically break when the source Excel file is renamed, deleted, or moved to a different folder. Moving the PowerPoint presentation to a different computer without also moving the source Excel file will also sever the connection.
How can I prevent linked files from crashing PowerPoint?
Keep your Office software updated to the latest version, ensure the linked Excel file isn't overly large or corrupted, and verify that the file paths are accessible. If the issue persists, consider embedding the Excel data directly into the slide instead of linking it.
