  <p>i am using this code:</p>
  
  <pre><code>function JSONToTSVConvertor(JSONData, ReportTitle, ShowLabel, myTemplateName){
  
      //If JSONData is not an object then JSON.parse will parse the JSON string in an Object
      var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
      var TSV = '';    
      //Set Report title in first row or line
      //TSV += ReportTitle + '\r\n\n';
      //This condition will generate the Label/Header
      if (ShowLabel) {
          var row = "";
          //This loop will extract the label from 1st index of on array
          for (var index in arrData[0]) {
              //Now convert each value to string and tab-seprated
              row += index + '    ';
          }
          row = row.slice(0, -1);
          //append Label row with line break
          TSV += row + '\r\n';
      }
  
      //1st loop is to extract each row
      for (var i = 0; i &lt; arrData.length; i++) {
          var row = "";
          //2nd loop will extract each column and convert it in string tab-seprated
          for (var index in arrData[i]) {
              row += '"' + arrData[i][index] + '" ';
          }
          row.slice(0, row.length - 1);
          //add a line break after each row
          TSV += row + '\r\n';
      }
  
      if (TSV == '') {        
          alert("Invalid data");
          return;
      }   
      var blob = new Blob([TSV], {type: "data:text/tsv;charset=utf-8"});
      //Generate a file name
  
      var fileName = myTemplateName;
      //this will remove the blank-spaces from the title and replace it with an underscore
      fileName += ReportTitle.replace(/ /g,"_"); 
      saveAs(blob, ""+fileName+".tsv");
  }
