Hi, I'm not sure if other folks have figured out how to do this, but I also wanted to "export" my Main menu paths, and could not find anything...
What I just figured out, for better or worse is that I can:
1) go to a menu, e.g. General Ledger, choose "Expand"

4) You can then manipulate it to look like:

It's at least way faster than manually copying & pasting menus/items
Hope this helps someone
Cheers,
Rich
