推荐答案

您可以使用XLSX导出到excel.

You can use XLSX for export to excel.

它将支持json或excel数组.

It will support json or array into excel.

示例代码

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);
}

保存

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);
}
