...
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { TableModule } from 'primeng/table';
import { DropdownModule } from 'primeng/dropdown';

@NgModule({
 ...
  imports: [
   ...
    BrowserAnimationsModule,
    TableModule,
    DropdownModule,
    ButtonModule
  ],
  ...

Step 4 – Display the data in the template

Next, you need to create html table with export excel button in angular app. So, visit src/app/ and app.component.html and update the following code into it:

<p-table [value]="sales">
    <ng-template pTemplate="caption">
        <div class="p-d-flex">
           
            <button type="button" pButton pRipple icon="pi pi-file-excel" (click)="exportExcel()" class="p-button-success p-mr-2"></button>

        <tr>
            
            <th pSortableColumn="brand">Brand <p-sortIcon field="brand"></p-sortIcon></th>

            <td>{{sale.thisYearProfit}}</td>
        </tr>
    </ng-template>
</p-table>

Step 5 – Add Code On app.Component ts File

Next, you need to visit the src/app directory and open app.component.ts. Then add the following code into the app.component.ts file:

...
export class AppComponent {
 ...
  ngOnInit() {
    this.sales = [
      { brand: 'Apple', lastYearSale: '51%', thisYearSale: '40%', lastYearProfit: '$54,406.00', thisYearProfit: '$43,342' },
      { brand: 'Samsung', lastYearSale: '83%', thisYearSale: '96%', lastYearProfit: '$423,132', thisYearProfit: '$312,122' },
      { brand: 'Microsoft', lastYearSale: '38%', thisYearSale: '5%', lastYearProfit: '$12,321', thisYearProfit: '$8,500' },
      { brand: 'Philips', lastYearSale: '49%', thisYearSale: '22%', lastYearProfit: '$745,232', thisYearProfit: '$650,323,' },
      { brand: 'Song', lastYearSale: '17%', thisYearSale: '79%', lastYearProfit: '$643,242', thisYearProfit: '500,332' },
      { brand: 'LG', lastYearSale: '52%', thisYearSale: ' 65%', lastYearProfit: '$421,132', thisYearProfit: '$150,005' },
      { brand: 'Sharp', lastYearSale: '82%', thisYearSale: '12%', lastYearProfit: '$131,211', thisYearProfit: '$100,214' },
      { brand: 'Panasonic', lastYearSale: '44%', thisYearSale: '45%', lastYearProfit: '$66,442', thisYearProfit: '$53,322' },
      { brand: 'HTC', lastYearSale: '90%', thisYearSale: '56%', lastYearProfit: '$765,442', thisYearProfit: '$296,232' },
      { brand: 'Toshiba', lastYearSale: '75%', thisYearSale: '54%', lastYearProfit: '$21,212', thisYearProfit: '$12,533' }
  ];
  
}

//excel button click functionality
exportExcel() {
  import("xlsx").then(xlsx => {
      const worksheet = xlsx.utils.json_to_sheet(this.sales); // Sale Data
      const workbook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
      const excelBuffer: any = xlsx.write(workbook, { bookType: 'xlsx', type: 'array' });
      this.saveAsExcelFile(excelBuffer, "sales");
  });
}
saveAsExcelFile(buffer: any, fileName: string): void {
  import("file-saver").then(FileSaver => {
    let EXCEL_TYPE =
      "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8";
    let EXCEL_EXTENSION = ".xlsx";
    const data: Blob = new Blob([buffer], {
      type: EXCEL_TYPE
    });
    FileSaver.saveAs(
      data,
      fileName + "_export_" + new Date().getTime() + EXCEL_EXTENSION
    );
  });
}

}

Step 6 – Start the Angular App

Finally, execute the following command on cmd to start angular project server:

ng serve

Visit http://localhost:4200/ to see your Angular app with the data table and the “Export to Excel” button. When you click the button, it will download the data as an Excel file.
