Problem:
How can I truncate the output of a Field to a specified amount of characters?

Solution:
There is no inbuilt solution for that unless for the excerpt shortcode.

For other fields, you might find this custom solution helpful:

Problem:
Can we change a user role thru a Toolset Form?
If so, how?

Solution:
You can, but only using Custom Code.
You can see a cred_save_data() hook to fire your custom code when the Form saves the users' data in the database.

Inside that hook, you can use wp_update_user() WordPress API to update the user to any role you desire.
For example, you can add a Generic Field to the form where the user can choose his role to which to update, and then you can read it from the $_POST - so to update the user to the desired role with wp_update_user()

Be careful with this as users will be able to eventually change their role.
Be sure to grant access to these forms only to whom you trust.
