title: Nested JSON file into Pandas Dataframe
body: <p>I'm having trouble getting this nested JSON object into a pandas dataframe using python:</p>
  
  <pre><code>{
     "count":275,
     "calls":[
        {
           "connectedTo":"18885068980",
           "serviceName":"",
           "callGuid":"01541af0-d87c-4911-a868-f5ac573d1e31",
           "origin":"+19178558701",
           "stateChangedAt":"2016-04-15T18:21:23Z",
           "sequence":9,
           "appletName":"ACD Sales General"
        }
     ]
  }
  </code></pre>
  
  <p>I've tried using json_normalize and am going in circles. Any help would be very much appreciated! </p>
