Jolt Transform Structure

[#1]

Hi, I'm trying to develop a Jolt Spec for the following transform:

JSON Input:

[
    {
        "randomkeyname1": "randomvalue1"
    },
    {
        "randomkeyname11": "randomvalue11",
        "randomkeyname22": "randomvalue22"
    },
    {
        "randomkeyname111": "randomvalue111",
        "randomkeyname222": "randomvalue222",
        "randomkeyname333": "randomvalue333"
    }
]

JSON Output:

[
    {
        "data": [
            {
                "key": "randomkeyname1",
                "value": "randomkeyvalue1"
            }
        ]
    },
    {
        "data": [
            {
                "key": "randomkeyname11",
                "value": "randomkeyvalue11"
            },
            {
                "key": "randomkeyname22",
                "value": "randomkeyvalue22"
            }
        ]
    },
    {
        "data": [
            {
                "key": "randomkeyname111",
                "value": "randomkeyvalue111"
            },
            {
                "key": "randomkeyname222",
                "value": "randomkeyvalue222"
            },
            {
                "key": "randomkeyname333",
                "value": "randomkeyvalue333"
            }
        ]
    }
]

 
I've tried many things but I'm newbie to this and didn't find anyone with similar issue.

The closest result that I managed to get was with the following Spec:

[{
  "operation": "shift",
  "spec": {
    "*": {
      "*": {
        "$": "data[#2].key",
        "@": "data[#2].value"
      }
    }
  }
}]

Which gave me the following output:

{
    "data" : [ {
      "key" : [ "randomkeyname1", "randomkeyname11", "randomkeyname111" ],
      "value" : [ "randomvalue1", "randomvalue11", "randomvalue111" ]
    }, {
      "key" : [ "randomkeyname22", "randomkeyname222" ],
      "value" : [ "randomvalue22", "randomvalue222" ]
    }, {
      "key" : "randomkeyname333",
      "value" : "randomvalue333"
    } ]
  }

Note: I don't know how many values, key names nor root level arrays I'm getting, is somewhat random.

I appreciate any help or ideas, thanks in advance!

Hi everyone, the following spec did the trick!

[{
  "operation": "shift",
  "spec": {
    "*": {
      "*": {
        "$": "[&2].data[#2].key",
        "@": "[&2].data[#2].value"
      }
    }
  }
}]
