How to convert JSON to CSV format and store in a variable

I have a link that opens up JSON data in the browser, but unfortunately I have no clue how to read it. Is there a way to convert this data using JavaScript in CSV format and save it in JavaScript file?

The data looks like:

{
  "count": 2,
  "items": [{
    "title": "Apple iPhone 4S Sale Cancelled in Beijing Amid Chaos (Design You Trust)",
    "description": "Advertise here with BSA Apple cancelled its scheduled sale of iPhone 4S in one of its stores in Chinau2019s capital Beijing on January 13. Crowds outside the store in the Sanlitun district were waiting on queues overnight.

    "id": "2388575404943858468"
  }, {
    "title": "Apple to halt sales of iPhone 4S in China (Fame Dubai Blog)",
    "description": "SHANGHAI u2013 Apple Inc said on Friday it will stop selling its latest iPhone in its retail stores in Beijing and Shanghai to ensure the safety of its customers and employees. Go to SourceSource : Fame Dubai BlogExplore : iPhone, iPhone 4, Phone",

    "type": "blogs",

    "id": "16209851193593872066"
  }]
}

The closest I could find was: Convert JSON format to CSV format for MS Excel

But it downloads in a CSV file, I store it in a variable, the whole converted data.

Also would like to know how to change escape characters: 'u2019' back to normal.

I tried this code:

      }
      $('div').html(str);

<body>
  <div></div>

</html>

But it doesn’t seem to work. Can someone please help?

Ok I finally got this code working:

    <script type="text/javascript" src="https://github.com/douglascrockford/JSON-js/raw/master/json2.js"></script>

    <script type="text/javascript">
        // JSON to CSV Converter
        function ConvertToCSV(objArray) {
            var array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;
            var str = '';

            for (var i = 0; i < array.length; i++) {
                var line = '';
                for (var index in array[i]) {
                    if (line != '') line += ','

                    line += array[i][index];
                }

                str += line + 'rn';
            }

            return str;
        }

        // Example
        $(document).ready(function () {

            // Create Object
            var items = [
                  { name: "Item 1", color: "Green", size: "X-Large" },
                  { name: "Item 2", color: "Green", size: "X-Large" },
                  { name: "Item 3", color: "Green", size: "X-Large" }];

            // Convert Object to JSON
            var jsonObject = JSON.stringify(items);

            // Display JSON
            $('#json').text(jsonObject);

            // Convert JSON to CSV & Display CSV
            $('#csv').text(ConvertToCSV(jsonObject));
        });
    </script>
</head>
<body>
    <h1>
        JSON</h1>
    <pre id="json"></pre>
    <h1>

Thanks alot for all the support to all the contributors.
