How to disable add-ins in office excel

Click the Office Button, click Excel Options, and then click Add-ins.

View add-ons and application extensions classified as follows:

Active Application Add-ins Lists extensions that are registered in Office programs and are currently running.

Inactive Application Add-ons Lists add-ons that are present on the computer but are not currently loaded. For example, smart tags or XML schemas are only activated when the document that references them is open. Another example is the COM add-ins listed in the COM Add-ins dialog box. If you select a COM add-in's check box, the add-in is activated. If you clear the check box for a COM add-in, the add-in is inactive. To learn how to open the COM Add-Ins dialog box, see the section Turning off or managing installed add-ins.

Document-related add-ins List template files referenced by the currently open document.

Disabled Application Add-ins Lists add-ins that are automatically disabled because they cause Office programs to crash.

Click the "Office Button" and then click "Excel Options".

Click "Trust Center", "Trust Center Settings" and "Add-ins" in sequence.

Click on the desired option. These settings are not selected by default unless you work in an organization and your information technology (IT) administrator has changed these default settings using administrator policies.

Have application add-ins signed by a trusted publisher Select this option if you want Trust Center to check the digital signature on the dynamic link library file that contains the add-in. If the publisher is not yet trusted, the Office program does not load the add-in, and a message bar appears with a notification that the add-in is disabled.

Disable unsigned add-in notifications (code will remain disabled) This checkbox is only available if the "Have application extensions signed by a trusted publisher" checkbox is selected. In some cases, the dynamic link library file containing the add-in may not be signed. In this case, add-ons signed by trusted publishers are enabled and unsigned add-ins are automatically disabled.

Disable all application add-ons (may affect functionality) Select this checkbox if you do not trust any add-ons. All add-ons will be disabled without any notification, and no other add-in checkboxes will be available.

Note This setting will only take effect after exiting and restarting the Office program.
