I am developing customer functions with Yeoman for Excel Add-in. We can use cmd, the npm run build to build add-in and insert to excel, and we also can insert the add-in by upload the "manifest". But once we uploaded/insert the add-ins, how can we remove/delete the developer add-ins we don't use/want anymore?

The developer Add-ins shows: enter image description here

Once I clicked to "See All", I can not see any developer Add-ins: enter image description here

Then I tried to find/delete the developer add-ins from options add-ins part, I still can not find it and delete it. enter image description here

I also tried the online version excel, also can not delete the add-ins I don't want anymore...

Does anyone know what can I do? Thanks!

To remove an add-in that you've previously sideloaded on Windows, Mac, or iOS, you need to clear the Office cache on your computer. In your case you just need to delete the contents of the Wef folder. You can find it in the following path:

%LOCALAPPDATA%\Microsoft\Office\16.0\Wef\

If the following folder exists, delete its contents too.

%userprofile%\AppData\Local\Packages\Microsoft.Win32WebViewHost_cw5n1h2txyewy\AC\#!123\INetCache\

Read more about that in the Clear the Office cache article.

Previous answer is really helpful. For Mac, which was my case, the path to the Wef folder is

/Users/%username%/Library/Containers/com.microsoft.Excel/Data/Documents/wef

The other folder doesn't exist

You have to remove it from the registry. Search for the Add-in Guid in the Registry and remove the instance from the Registry and the Add-ins will no longer be listed in Excel.
