It seems you are encountering an unexpected error while trying to create a copy of your workbook in Excel for the web. This type of error can sometimes be related to temporary issues with the service or specific features that may not be supported in Excel Online. Here are a few steps you can try to resolve the issue:
- Refresh the Page: Sometimes, simply refreshing the browser can help resolve temporary glitches.
- Clear Browser Cache: Clearing your browser's cache and cookies can help eliminate any corrupted data that might be causing the issue.
- Try a Different Browser: If the problem persists, try accessing Excel Online from a different web browser to see if the issue is browser-specific.
- Check for Service Outages: Visit the Microsoft 365 Service Health page to check if there are any ongoing issues with Excel Online.
- Use the Desktop App: If you have access to the desktop version of Excel, consider using it to create the copy, as it may handle features better than the online version.
If these steps do not resolve the issue, you may want to consider reaching out to Microsoft Support for further assistance.
