Fix Excel for the Web Cannot Create a New Workbook Error
Question details
The user is unable to create a new spreadsheet in Excel for the web and encounters an error preventing document creation.

- Product
- Excel for the Web
- Device & OS
- Windows
- Scenario
- Attempting to create a new Excel workbook via 'File > New' in the web browser or using an Excel add-in that calls the createWorkbook API.
- Observed behavior
- Excel displays a 'Sorry, we couldn't create your new document' message, and add-ins return an internal Rich API error, though creating files directly from OneDrive might still work.
Verify that your internet connection is stable and ensure you have not exceeded your Microsoft OneDrive storage limit before attempting to troubleshoot authentication issues.
Clear Credentials and Reset OneDrive Sync
Clearing outdated login tokens and resetting the OneDrive client is the most effective way to resolve the authentication conflicts preventing workbook creation.
Often, backend synchronization issues between Excel for the web and OneDrive are caused by corrupted cached credentials on your Windows machine or browser.
Sign out of your Office and OneDrive accounts in your browser. Close all tabs, then navigate to your browser's settings to clear cookies, cached images, and temporary site data.
Click the Windows Start button, type 'Credential Manager', and open it. Under 'Windows Credentials', locate and remove any saved credentials related to Microsoft Office or OneDrive.
Press the Windows key + R to open the Run dialog box. Type 'OneDrive.exe /reset' and press Enter to reset the sync client.
Reopen your browser, sign back into Microsoft 365, open Excel for the web, and click 'File > New' to check if the workbook creation functions normally.

Create the Workbook Directly from OneDrive Web
If the Excel web interface continues to fail, you can bypass the error by creating the file directly from your OneDrive directory.

Frequently Asked Questions
Why does Excel for the web say 'Sorry, we couldn't create your new document'?
This error typically occurs due to corrupted browser cache, expired session credentials, or internal server-side API issues when the Excel web app attempts to communicate with your OneDrive storage.
What is an internal Rich API error in Excel add-ins?
An internal Rich API error happens when an Excel web add-in attempts to execute a specific command, like 'createWorkbook', but fails because the underlying Office JavaScript API has lost its connection or permissions to the cloud storage platform.
Will resetting OneDrive using the Run command delete my files?
No, running the 'OneDrive.exe /reset' command only resets the sync client's settings and clears internal sync queues. Your actual files stored in the cloud or on your local drive remain completely safe and untouched.
