If the ExtendInsights add-in no longer appears in Excel, it is usually caused by a loading issue, an Office update, or a Microsoft 365 deployment change. Follow the steps below to restore the add-in.
Symptoms
You may experience one or more of the following:
The ExtendInsights ribbon or task pane is missing.
The add-in no longer appears in Excel.
You cannot open ExtendInsights from Excel.
The add-in disappeared after an Office or Microsoft 365 update.
Why This Happens
The ExtendInsights Excel add-in is delivered through Microsoft AppSource (Microsoft 365). In some situations, Excel may stop loading the add-in due to:
A Microsoft Office or Microsoft 365 update
A temporary Office add-in loading issue
A corrupted Office add-in cache
An organization-wide deployment or Microsoft 365 policy change
This behavior is related to Microsoft Office and is not specific to ExtendInsights.
How to Resolve the Issue
Step 1: Restart Excel
Close all Excel windows.
Wait approximately 30 seconds.
Reopen Excel.
Verify whether the ExtendInsights add-in has returned.
Many temporary loading issues are resolved by restarting Excel.
Step 2: Reinstall the Add-in
Open Excel.
Go to Home → Add-ins → More Add-ins.
Search for your licensed ExtendInsights application, such as:
ExtendInsights Data Connector
ExtendInsights Financial Reporting
Select Add to reinstall the add-in.
Step 3: Clear the Office Add-in Cache
If the add-in appears in Microsoft AppSource but still does not load correctly:
Clear the Office add-in cache.
Restart Excel.
Reinstall the ExtendInsights add-in if prompted.
For detailed instructions, see Troubleshooting: Clear the Office Add-in Cache.
Step 4: Contact Your Administrator or Extend Support
If the add-in is missing for multiple users in your organization:
Contact your Microsoft 365 Administrator to verify the add-in deployment.
If the deployment appears correct, contact our Support for assistance.
Verification
The issue is resolved when:
The ExtendInsights add-in appears in Excel.
The ExtendInsights task pane opens successfully.
You can sign in and access your ExtendInsights features.
Best Practices
Keep Microsoft Office updated.
Close Excel completely before reinstalling the add-in.
If your organization centrally deploys Office add-ins, work with your Microsoft 365 Administrator before reinstalling.
