Well,
RPA isnt different from the C# code. It makes it easier. Writing that code might have taken you months but RPA can do it within a few weeks (at most) if everything goes without a hitch.
You can use code snippets in the UiPath tool too, custom activities, .net code activities, VBA, VB Scripts… you name it.
I guess you can build a workforce of bots and then visualize it too using the custom logs.
Good luck with the migration (if you are planning on it))
Regards
