<p>You could take an iterative and recursive approach by checking header keeping the corresponding divider and iterate children.</p>

<p>Then you need to add the standard object for any item.</p>

<p>The recursive callback uses a closure over the group. if not set, the group is a root item.</p>

<p>I have a object which looks like this:</p>

<pre><code>[
  {
    "id": 1,
    "name": "Electronics",
    "path": "Electronics",
    "children": [
      {
        "id": 2,
        "name": "Laptops &amp; PC",
        "path": "Electronics &gt; Laptops &amp; PC",

      },
      {
        "id": 7,
        "name": "Phones &amp; Accessories",
        "path": "Electronics &gt; Phones &amp; Accessories",
        "children": [
          {
            "id": 8,
            "name": "Smartphones",
            "path": "Electronics &gt; Phones &amp; Accessories &gt; Smartphones",
            "children": [
              {
                "id": 9,
                "name": "Android",
                "path": "Electronics &gt; Phones &amp; Accessories &gt; Smartphones &gt; Android",
                "children": []
              },
              {
                "id": 10,
                "name": "iOS",
                "path": "Electronics &gt; Phones &amp; Accessories &gt; Smartphones &gt; iOS",

      }
    ]
  },
  {
    "id": 11,
    "name": "Software",
    "path": "Software",
    "children": []
  }
]
</code></pre>

<p>And I wanted to convert it to something like this:</p>

<pre><code>[
  {header: 'Electronics'},
  {name: 'Laptops &amp; PC', group: 'Electronics', id: 2},
  {name: 'Phones &amp; Accessories', group: 'Electronics', id: 7},
  {name: 'Smartphones', group: 'Phones &amp; Accessories', id: 8},
  {name: 'Android', group: 'Smartphones', id: 9},
  {name: 'iOS', group: 'Smartphones', id: 10},
  {divider: true},
  {name: 'Software', group: 'Software', id: 11}
]
</code></pre>

<p>Basically, </p>

<ul>
<li>If a root element has children, it should be converted as <code>header</code>.</li>
<li>All the elements should have its parent name as <code>group</code></li>
<li>When finished with one root element, It needs to insert <code>{divider: true}</code> before proceeding to the next. (If it's the last root element, do not insert <code>{divider: true}</code></li>
</ul>

<p>While I was able to find lots of Hierarchical to JSON solutions on stackoverflow, I was not able to reverse engineer those solutions.</p>

<p>Can somebody please help me?</p>
