Disable Copilot in Excel Fast

Applies to: Excel for Microsoft 365 on Windows (current channel), Excel for Mac (notes included), and Excel on devices where Copilot appears in the ribbon.

Goal: Turn off Copilot in Excel—either just on this device/account or tenant-wide (admins). Interlinks below point to related Digital Citizen tutorials.

Before you start

  • Account type: Some options require an administrator (for org-wide control).
  • Version note: Recent Excel builds expose a dedicated Enable Copilot checkbox per app.
  • Back up first: If you’ll touch policies/registry, learn how to open the Local Group Policy Editor and how to open the Registry Editor safely: open gpedit, open regedit, navigate the registry.

Method 1 — Turn off Copilot inside Excel (fastest, per-app/per-device)

  1. Open Excel.
  2. Go to File → Options → Copilot.
  3. Uncheck “Enable Copilot.”
  4. Select OK, then restart Excel.

What this does: Disables Copilot only for Excel on this device. To disable in Word/PowerPoint/OneNote too, repeat in each app.

Method 2 — Block Copilot via Office privacy controls (no admin needed)

Use Office’s privacy controls that Copilot relies on.

Windows (Microsoft 365):

  1. File → Account → Account Privacy → Manage Settings.
  2. Turn off:
    • Connected experiences that analyze your content
    • (Optionally) Optional connected experiences
  3. Restart Excel.

Older/volume builds & alternate path:

  1. File → Options → Trust Center → Trust Center Settings → Privacy Options → Privacy Settings…
  2. Uncheck “Enable optional connected experiences,” and turn off content-analysis experiences.
  3. OK → OK, restart Excel.
    If you need a refresher on Trust Center paths, see how to use Trust Center in Excel concepts inside enable macros in Excel (same Trust Center navigation).

Method 3 — Remove/hide the Copilot button from the ribbon (UI only)

  1. Right-click the ribbon → Customize the Ribbon.
  2. In the right pane, locate the Copilot group under Home (name may vary by build).
  3. Uncheck it or remove it from your custom tab layout.
  4. OK to save.

Note: This hides the button but doesn’t block Copilot features if they’re still enabled. Use Method 1 or 2 for enforcement.

Method 4 — Admin: Turn off Copilot for users (tenant-wide)

Best for: Microsoft 365 Business/Enterprise.

Options you can apply (pick one or combine):

  • License control: Remove or unassign the Copilot for Microsoft 365 add-on license from targeted users/groups.
  • Service/app control: In the Microsoft 365 Admin/Apps Admin Center, disable Copilot service/app availability for Excel (and other Office apps) for selected users.
  • Cloud Policy/Intune/GPO: Deploy policy to turn off connected experiences that analyze content (and, if needed, optional connected experiences) for Office apps. This blocks Copilot features across Excel, Word, PowerPoint, OneNote, Outlook on managed devices.

Method 5 — Group Policy or Registry (IT enforcement on Windows PCs)

Group Policy (device or user scope):

  • Use Microsoft 365 Apps policy to disable connected experiences that analyze content (and optionally all/optional connected experiences).
  • After applying policy, run gpupdate /force and have users restart Excel.

Registry (when policy editors aren’t available):
Use the privacy policy keys for Microsoft 365 Apps (device or user scope) that turn off content-analysis/optional connected experiences, then restart Excel. If you’re new to Registry work, review open regedit and navigate the registry first.

Verify Copilot is disabled

  • The Copilot button is gone (Method 3) and/or greyed out.
  • No Copilot pane/suggestions appear in Excel after restart.
  • If you disabled content-analysis experiences, Copilot features are unavailable across Office apps on that device/account.

Undo or change scope later

  • Re-enable per app: File → Options → Copilot → Enable Copilot.
  • Privacy controls: Turn connected experiences back on and restart Excel.
  • Org-wide: Reassign licenses or relax the Office policy.

Troubleshooting

  • You don’t see “Copilot” in Options. Update Office to the latest build; some channels added a Copilot page to File → Options more recently.
  • Button hides but prompts still show. Hiding the ribbon entry doesn’t disable features. Use Method 1 or 2.
  • Controlled by your company. If Account Privacy is locked, your admin enforces policy—ask IT.
  • Mac users: Excel (menu) → Settings/Preferences → Copilot (or Privacy) to toggle off; managed Macs can be governed by org policy as well.
