To fix an Excel add-in that keeps loading, first identify the correct account, file, device, or service context. The steps below isolate the cause and apply a result you can verify.
Protect the Workbook and Isolate the Affected Excel Feature
Start by confirming whether the symptom affects one file, one device, one account, or the service itself. That distinction determines whether the next action belongs in the desktop app, the web portal, or an administrator console.
Quick Excel Check
First, check your internet connection. Next, sign out and sign back in, and verify the final state before changing any backup or secondary account.
Why This Can Happen
- The wrong personal, work, school, billing, or administrator account is selected
- A license, permission, connection, file rule, or local setting does not match the requested action
- Cached credentials or an incomplete synchronization or activation state hides the current server status
- The workbook or Excel configuration requires a more specific control than a generic restart
How to Fix an Excel Add-In That Keeps Loading

- Check your internet connection
- Sign out and sign back in
- Close Excel completely, reopen it, and sign in again
- Clear the Office cache
- Open this path in the address bar from File Explorer: %localappdata%\Microsoft\Office\16.0\Wef\
- Restart Excel afterward
After the final step, reopen the affected app, portal, file, or account page and confirm the exact status or behavior described in the title.
WPS Office: A Free Alternative for Local Office Work

WPS Office cannot directly change Microsoft-side account, billing, subscription, activation, tenant, OneDrive service, or SharePoint permission state. Those changes must be completed in the appropriate Microsoft portal.
For local productivity, WPS Office is a free Microsoft Office-compatible alternative with Writer, Spreadsheets, Presentation, and PDF tools. It opens and saves major formats including DOCX, XLSX, PPTX, and PDF through a familiar, streamlined interface that supports a smooth everyday migration.
Test advanced macros, add-ins, external connections, sensitivity controls, and Microsoft-only cloud integrations on a copy before moving a critical workflow.
Practical Checks That Prevent a Repeat
- Record which account, app, and file owns the workflow
- Keep a verified backup before removing access, changing ownership, or replacing a local file
- Apply high-impact changes to one test item or user before expanding the scope
- Save confirmation numbers, dates, and screenshots of the final settings when they affect billing, security, or permissions
