Support hierarchal JSONs

Currently the module lacks support for hierarchal JSONs. i.e:

{
  "success": true,
  "status": 200,
  "data": {
    "makes": ["AC", "Acura", "Alfa Romeo", ...],
    "makesWithModels": {
      "AC": ["Aceca"],
      "Acura": ["CL", "CSX", "EL", "ILX", ...],
      ...
    }
  },
  "message": "Successfully retrieved make-model mapping"
}

Would this be possible to implement?
