Convert Profile Permissions to Permission Sets with Salesforce Helper App

Profile and Permission Set Helper allows admins to create permission sets from standard or custom user profiles. The generated permission set includes all permissions from the selected profile and is immediately assignable to one or multiple users.
The app simplifies management of user profile and permissions when admins need to upgrade user licenses. Admins can also assign permissions to new users based on an existing profile. Transition from profiles to perm sets easily!
