title: How to format Json output
body: <p>Please help me how to get JSON output as below:</p>
  
  <pre><code>{
     "_costMethod": "Average",
     "fundingDate": 2008-10-02,
     "fundingAmount": 2510959.95
  }
  </code></pre>
  
  <p>Instead of: </p>
  
  <pre><code>{
     "@type": "sma",
     "costMethod": "Average",
     "fundingDate": "2008-10-02",
     "fundingAmount": "2510959.95"
