Disappearing Add-in ribbon

Sometimes you need to do additional steps. One of the most frustrating issues is the disappearing add-in ribbon effect. A recent Excel update has caused add-in Ribbon Menu Bars to disappear when Excel is opened. We’ll show the solution on how to fix it. Let us see the solutions!

If your add-in has not appeared on the ribbon, unblock the file or move the file into a trusted location. You will learn how to do it.

The difference between .xlsx and .xlsm (.xlam) files: If you are open a normal (macro-free) Excel file, nothing will happen. If you are working with add-in files, Excel will never inform you; you can open the file without any security message.

Unblocking add-ins

When you get the macro-enabled file from the internet, the file is blocked by default.

Steps the unblock an Excel file:

  1. Right-click the add-in file
  2. Select Properties
  3. Locate the General tab, Security section.
  4. Mark the Unblock box checked
  5. Click the OK
