What is the best way to parse out a value from a user object?

I have a custom field that is a typeahead from the user object.

In Fusion, that custom field is passed as:
'{"objCode":"USER","name":"Anushka XXXX","ID":"64ad05ec00xxxx52aed8fa3f4"}

Is there an easy way to parse out the name or ID out of this?  Can I do this with a map() function?
