Retrieving JSON return value from function and parsing in Construct 2

I would like to know how to parse a JSON object and parse each value into either an array, or something that I can use to set values of several global variables in my project file. I want to avoid editing the Javascript file itself, so please try to provide an approach that can be done in Construct itself rather than an external way.

Code sample

 axonify.game = {
  gameData: function() {
    data = {
      name: 'Block Mania',
      timeLimit: 30,
      addedTimePerQuestion: 0,
      addedTimePerCorrectQuestion: 15,
      questionCount: questionCount
    };
    return data;
  },
