title: How to convert a json object into .csv file and how to export using Ionic 2 + angular 2?
body: <p>I'm using a function in my angular 2 application to convert and export a JSON data into .CSV. The below is my function and is working fine in angular 2 application 
  (web). The Same I tried to use in mobile app which I developed using Ionic 2, it is not working in mobile app. Is there any way to do this?</p>
  
  <p>Thanks!</p>
  
  <pre><code>saveAsCSV() {
         let sampleJson : any = [{name:'ganesh', age:'24'},{name:'ramesh', age:'24'},{name:'suresh', age:'24'}]
         this.saveData = [];    
         let a = document.createElement("a");    
          a.setAttribute('style', 'display:none;');    
          document.body.appendChild(a);    
         let csvData = ConvertToCSV(sampleJson);    
         let blob = new Blob([csvData], { type: 'text/csv' });    
         let url= window.URL.createObjectURL(blob);    
          a.href = url;    
          a.download = 'sample.csv'; 
          a.click();    
    }
  
  ConvertToCSV(objArray) {    
          let array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;
          let str = '';
          let row = ""; 
          for (let index in objArray[0]) {
              //Now convert each value to string and comma-separated
              row += index + ',';
          }
          row = row.slice(0, -1);
          //append Label row with line break
          str += row + '\r\n';
  
          for (let i = 0; i &lt; array.length; i++) {
              let line = '';
              for (let index in array[i]) {
                  if (line != '') line += ',';
                  line += array[i][index];
              }
              str += line + '\r\n';
