Export to Excel on Angular 4

Question

I have a data table that is dynamically populated using Angular 4. I would like to export the table to excel. How can I achieve this in Angular 4. I'm looking for .xls and not .csv.

PS: I don't want to use Jquery libraries.

My app-component looks like this,

    <table id ="dataTable" class = "table table-hover">
  <thead>
      <tr>
          <th>Date</th>
          <th>Address</th>
          <th>Mode</th>
          <th>Distance</th>
          <th>Fare</th>
          <th></th>
      </tr>
  </thead>
  <tbody>
      <tr *ngFor="let date of dateList;let i = index">
          <td>{{date}}</td> 
          <td>{{address}}</td>
          <td>{{mode}}</td>
          <td>{{distance}}</td>
          <td>{{fare}}</td>
          <td>
             <a>Delete</a>
          </td>   
      </tr>
  </tbody>
</table>

Answer 1

For those who are still looking for a working answer.

public export() {
    const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(this.myDataModels);
    /* generate workbook and add the worksheet */
    const wb: XLSX.WorkBook = XLSX.utils.book_new();
    XLSX.utils.book_append_sheet(wb, worksheet, 'Sheet1');
    /* save to file */
    XLSX.writeFile(wb, this.createFileName());
}

This will save as an xlsx file automatically Got this from https://github.com/SheetJS/js-xlsx/tree/19620da30be2a7d7b9801938a0b9b1fd3c4c4b00/demos/angular2

You can use XLSX for export to excel.

It will support json or array into excel.

Sample code

import * as XLSX from 'xlsx';

public exportAsExcelFile(json: any[], excelFileName: string): void {
  const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(json);
  const workbook: XLSX.WorkBook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
  const excelBuffer: any = XLSX.write(workbook, { bookType: 'xlsx', type: 'buffer' });
  this.saveAsExcelFile(excelBuffer, excelFileName);
}

For Save

private saveAsExcelFile(buffer: any, fileName: string): void {
  const data: Blob = new Blob([buffer], {
    type: EXCEL_TYPE
  });
  const today = new Date();
  const date = today.getFullYear() + '' + (today.getMonth() + 1) + '' + today.getDate() + '_';
  const time = today.getHours() + "-" + today.getMinutes() + "-" + today.getSeconds();
  const name = fileName + date + time;
  FileSaver.saveAs(data, name + EXCEL_EXTENSION);
}
