How to Stop Excel Online Stock Connector Add-In from Opening Automatically
Product
Excel Online
Device & OS
MacBook Air (Microsoft Edge)
Scenario
Reopening an existing spreadsheet in Excel Online via a web browser.
Observed behavior
The Stock Connector add-in opens automatically upon loading the spreadsheet. Clearing the browser cache does not resolve the issue, and the add-in continues to reappear or prompt for reinstallation even after being removed.
Before you start

Ensure you are logged into the correct Microsoft account in Excel Online and check if the issue occurs across multiple different workbooks or just one specific file.

Solution 1Recommended

Remove or Hide the Stock Connector Add-In

Manage your active add-ins directly within Excel Online settings to remove extensions you no longer want to launch automatically.

If you no longer need the Stock Connector, removing it from your account is the most direct way to stop it from loading. Note that some add-ins only offer a 'Remove' option rather than 'Hide'.

1
Open Add-in Management

In Excel Online, navigate to the top ribbon, click on the 'Insert' tab, and select 'Add-ins'.

2
Access Your Add-ins

Click on 'My Add-ins' or go to 'File' > 'Get Add-ins' > 'Manage My Add-ins' to view your currently installed extensions.

3
Remove the Add-in

Locate 'Stock Connector' in the list, click the three-dot menu icon next to it, and choose 'Remove' (or 'Hide' if available).

Remove or Hide the Stock Connector Add-In
Add-in Reinstallation Prompts: If the specific workbook still contains active data connections linked to the Stock Connector, Excel may continuously prompt you to add it back when opening that file.

Frequently Asked Questions

Why does the Stock Connector add-in reappear after I delete it?

If an add-in is heavily integrated into a specific workbook's formulas or data connections, the file itself may trigger a prompt to reinstall it upon reopening. You must remove all linked data types inside the workbook to stop this trigger.

Can clearing my Microsoft Edge cache stop Excel add-ins from loading?

Typically, no. Add-in preferences are saved to your Microsoft account or the workbook file itself on the server side. Clearing the local browser cache on your Mac will not change the add-in's core behavior.

Where is the option to hide add-ins in Excel Online?

You can usually find this by navigating to File > Get Add-ins > Manage My Add-ins. However, depending on how the third-party developer configured it, some add-ins can only be removed completely rather than just hidden from view.
