Ability to get username in Excel
I'd like to be able to access the username listed under Account -> User Information in my add-in in Microsoft Office Excel 2016.
Besides being able to customize the add-in experience and address the user by first name, having the full name would allow me to look up internal users and perform more advance functions like looking up permissions or recording their userId along with actions they perform.
You can write a function that does this in VBA already, and it's not very hard, but the issue with your idea is that on networked systems - it could be a security concern. However, you can also PowerQuery that information if there is a remote file with that information already stored.
