You can parse JSON with ruby from a hash:

require 'json'

my_hash = JSON.parse('{"hello": "goodbye"}')
puts my_hash["hello"] => "goodbye"

Or generate it from a hash:

require 'json'

my_hash = {:hello => "goodbye"}
puts JSON.generate(my_hash) => "{\"hello\":\"goodbye\"}"

Have a look at the JSON documentation.
