I want to add additional property to json string without transform the String to any object format
<p>I want to add additional property to json string without transform the String to any object format (I am doing the transformation right now which taking 30 ms time, i want to avoid the transformation time), so is there any way to add property to the json string without transform the payload to any object format?</p>

<p>Ex:</p>

<pre><code>{
  "type": "some type",
  "data": [{
    "email": "email id",
    "content": {
      "some filed": "filed value"
    }
  }]
}
</code></pre>

<p>i need my payload after the new field added like.,</p>

<pre><code>{
  "type": "some type",
  "data": [{
    "email": "email id",
    "content": {
      "some filed": "filed value",
      "new field": "New value"
    }
  }]
}
</code></pre>
