body: <p>I am writing a small scala practice code where my input is going to be in the fashion - </p>
  
  <pre><code>{
    "code": "",
    "unique ID": "",
    "count": "",
    "names": [
      {
        "Matt": {
          "name": "Matt",
          "properties": [
            "a",
            "b",
            "c"
          ],
          "fav-colour": "red"
        },
        "jack": {

          "properties": [
            "a",
            "b"
