Administrator for to locate, edit and save any user's data

I was able to very easily create a frontend form to allow users to edit and save their own profile data using Meta Box. I have a client who is asking for a form for website administrators to allow them to find, display, edit and save any user's profile data. I have searched the documentation for any information on how to do that but have found nothing. I have convinced them to give the Admin Columns Pro plugin a chance but I am not sure they are going to find it adequate for their use. If there is any information I've missed I would really appreciate being pointed to it.
