  /* generate worksheet */
  const ws: XLSX.WorkSheet = XLSX.utils.aoa_to_sheet(this.data);
  /* generate workbook and add the worksheet */
  const wb: XLSX.WorkBook = XLSX.utils.book_new();
  XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');
  // /* save to file */
  XLSX.writeFile(wb, 'Sheet2.xlsx');
