title: JSON Transformation with data manipulation using Apache NiFi
body: <p>I want to do some basic transformation to my below sample JSON, I want to change the value of the timeStamp tag to date format and want to add a new tag <code>created_ts</code> with value of <code>current_timestamp</code> to the my expected JSON output using NiFi.</p>
  
  <p><strong>Sample JSON</strong>:</p>
  
  <pre><code>{"name": "SAMPLE_NAME","timeStamp": "1477307252000","value": "-0.06279052","quality": "1090"}
  </code></pre>
  
  <p><strong>Expected JSON:</strong></p>
  
  <pre><code>{"name": "SAMPLE_NAME","timeStamp": "2016-11-08 14:46:13.674","value": "-0.06279052","quality": "1090","created_ts":"2016-11-08 14:46:13.674"}
  </code></pre>
