Open Excel after an add-in problem

Use Excel safe mode when desktop Excel closes during startup or doesn't open normally after an add-in change. Safe mode starts Excel without loading most add-ins.

Start Excel in safe mode

  1. Press and hold Ctrl.
  2. While you hold Ctrl, open Excel.
  3. When Excel asks whether to start in safe mode, select Yes.

You can also press Windows key + R, enter excel /safe, and select OK.

Disable MarketXLS temporarily

  1. In safe mode, select File > Options > Add-ins.
  2. At the bottom of the window, select COM Add-ins from Manage.
  3. Select Go.
  4. Clear the MarketXLS checkbox.
  5. Select OK, and then close Excel.
  6. Open Excel normally.

If Excel now opens, the issue involves MarketXLS or an interaction with another add-in.

Isolate an add-in conflict

  1. Disable other nonessential COM add-ins.
  2. Enable MarketXLS.
  3. Close and reopen Excel.
  4. Re-enable the other add-ins one at a time, restarting Excel after each change.

If Excel fails when a particular combination is enabled, contact MarketXLS support and include the names and versions of the affected add-ins.

If Excel doesn't open even when MarketXLS is disabled, use Microsoft's Excel startup and repair guidance or contact your Microsoft 365 administrator.
