Loading firebase database to Power BI

Hello

I have been searching all over to learn how to import Firebase JSON database into a Power BI table. Problem with most existing Q&A is that they all use key value pairs when selecting the json. Firebase uses nested objects. Still, I know my data well, so I hope someone could help me with the right selectors for the Query Editor.

Here's my data:

{
    "5d33cb83fd045541df50f14206f77212": {
        "691c32e30f0d255bf060007d91595e4b": {
            "-Kd0ZscC1DSkXg9Tl61w": {

                "telltruthtospouse": "10"
            }
        },
        "ec1ba86ec0730d1234f84a979764a72f": {
            "-Kd0ZEiB6exMkmEmja7I": {

            }
        }
    },

        "ae258795f6f053cfe8ea939baf37a20b": {

                "r": "bac16f8edfe59f53fcf9270b951fcd1e",
                "score": "18",
                "telltruthtospouse": "3"
            },
            "-Kd0G2W2hLMnZJ1vVJ1C": {
                "date": "2017-02-13",
                "eatmyvegetables": "8",
                "postponeuntildeadline": "7",
                "r": "bac16f8edfe59f53fcf9270b951fcd1e",
                "score": "18",
                "telltruthtospouse": "3"
            },
            "-Kd0HO8VVZooG8iy0r6N": {
                "date": "2017-02-13",
                "eatmyvegetables": "8",
                "postponeuntildeadline": "7",
                "r": "bac16f8edfe59f53fcf9270b951fcd1e",
                "score": "18",
                "telltruthtospouse": "3"
            }
        }
    }
}

And here is the result I am looking for (which also gives a better overview of the data itself):

I know how to load the JSON, but not how to select nodes without knowing their names and to put parents and childrens into the same rows.

Hope it makes sense and I hope your are able to help me.
