Within an Office Excel JavaScript Add in, I created a custom ribbon. Within that custom ribbon, I would like to include custom excel functions (e.g., remove duplicates).
Is it possible, to include such functions? If yes, what does an exemplary XAML code for the manifest file look like? Where can I find the relevant IDs for Excel?
I did not find any resources on possible code snippets. Further, I did not find any related articles for Excel JS Add-Ins specifically in the documentation?
