get Json array and generate rows and columns

Anonymous So, dumb question, but is this coming from a JSON file? Because something like this works fine when importing via JSON connection. 

{
	"_id": "61f872",
	"studyvalue": [{"from": 200000, "until": 700000, "value": 40000}, {"from": 700001, "until": 1200000, "value": 60000}, {"from": 1200001, "until": 11999999, "value": 80000}, {"from": 12000000, "until": -1, "value": 120000}],
	"paymentpercentage": "7"
}

Otherwise I believe you will need to use Json.FromValue:
