title: restAPI- how to format JSON value
body: <p>I am getting JSON value from my server and it works well. But I want to customize my JSON value. I have two questions:</p>
  
  <p>First, when I get region value, I get it like <code>["USA"],["Mexico"],["Canada"]</code>. Is there a way I can ignore the double quotes/brackets and just get the strings values like <code>USA, Mexico, Canada</code>?</p>
  
  <p>Second, when I get the regDate value I get the whole data like <code>2018-10-31T07:53:12.000Z</code> instead, can I ignore some values and get it like <code>2018-10-31 07:53</code>?</p>
  
  <pre><code>{
    "result": "ok",
    "data": [
        {
          "idx": 1,
          "region": "[\"USA \", \"Mexico \", \"Canada \"]",
          "regDate": "2018-10-31T07:53:12.000Z"
        }
     ]
  }
  </code></pre>
