Question details

The user needs to remove a third-party GPT add-in from Excel but is unable to use the standard uninstallation method due to account sign-in issues.

How to Uninstall the GPT Add-in from Excel

Product: Excel
Device & OS: not provided
Scenario: Attempting to uninstall a third-party add-in when sign-in requirements block the standard removal process.
Observed behavior: Normal uninstallation fails because the add-in prompts for a sign-in, preventing the user from accessing its removal options.

Before you start

Ensure that you have saved your work and are viewing a blank Excel workbook so you can safely access the Developer tab without interrupting active calculations.

Solution 1Recommended

Remove the Add-in via the Developer Tab

Bypass the add-in's interface and use Excel's built-in Developer settings to force the removal without signing in.

When an add-in requires you to sign in before you can manage its settings, you can use the native Office Add-ins menu to delete it. This method circumvents the third-party interface entirely.

Access the Developer Tab

Launch Microsoft Excel and click on the 'Developer' tab located in the top ribbon. If you do not see this tab, you can enable it by going to File > Options > Customize Ribbon, and checking the 'Developer' box.

Open Office Add-ins

In the Developer ribbon, click on the 'Add-ins' button. This will open the Office Add-ins dialog box where all your installed extensions are listed.

Remove the GPT Add-in

Locate the GPT for Word and Excel add-in in the list. Click the three-dot menu (...) next to the add-in name, and select 'Remove' from the dropdown menu to uninstall it completely.

Uninstallation Complete: The add-in will be immediately removed from your Excel interface without requiring any account credentials.

Frequently Asked Questions

Why is the Developer tab missing in my Excel?

By default, Microsoft Excel hides the Developer tab. To display it, right-click anywhere on the top ribbon, select 'Customize the Ribbon', and check the box next to 'Developer' in the right-hand column. Click OK to save.

Will removing the add-in delete the text it already generated?

No. Removing the GPT add-in only uninstalls the tool's interface and background processes from Excel. Any text, formulas, or data that were already inserted into your workbook will remain perfectly intact.

What should I do if the add-in reappears after restarting Excel?

If the add-in reinstalls itself automatically, it is likely being deployed by your organization's IT administrator via Microsoft 365 centralized deployment. You will need to contact your IT department to have it permanently removed from your account.
