title: Convert JSON data to two dimensional Array
body: <p>JSON Data sample:   </p>
  
  <pre><code> { 
          "GroupA": "Array[37]", 
          "AGroupC": "Array[9]", 
          "GroupB": "Array[12]", 
          "GroupE": "Array[15]", 
          "GroupF": "Array[21]", 
          "GroupD": "Array[6]" 
          }
  </code></pre>
  
  <p>I have the above data and I need to convert it to two dimensional array but don't know how to do it. Any help will be appreciated. 
  The resulting should look like:</p>
  
  <pre><code>["GroupA", "GroupC", "AGroupB", "GroupE", "GroupF", "GroupD"]
  [37, 9, 12, 15, 21, 6]
  </code></pre>
  
  <p>Thanks.</p>
