html to csv conversion using javascript

Question

I have been trying to convert html table into csv format by jquery table2csv plugin. Table values are downloading as expected. But only in word format. I can't open it using excel. if i use .csv while downloading data showing in excel. Here is my jquery code

    <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
    <script type="text/javascript" src="table2CSV.js" > </script>
    <script type="text/javascript">
      $(document).ready(function () {
      $('table').each(function () {
        var $table = $(this);

        var $button = $("<button type='button'>");
        $button.text("Export to spreadsheet");
        $button.insertAfter($table);

        $button.click(function () {
            var csv = $table.table2CSV({
                delivery: 'value'
            });
            window.location.href = 'data:text/csv;charset=UTF-8,'
            + encodeURIComponent(csv);
         });
     });
  })
  </script>
