Given the following Json input how do I write a Jolt spec to transform the input into the desired output below. I am unsure how to deal with nested data, and transformation of objects into arrays. I have experimented with different specs https://jolt-demo.appspot.com/#inception however I cannot seem to get the desired transformation.

INPUT

    "data": {
        "properties": {
            "info": { 
                "type": "object",

                "required": [
                "evalDate",
                "evalType",
                "evalWeather"
                ],

                        "type": "null"
                      }
                    ]
                  }
                }
              } ...
