导出XLS或CVS数据Angular 5

Question

嗨，我需要在angular5中导出表的数据，我正在使用API​​ xls并将文件保存为我的代码：

import { Injectable } from '@angular/core';

import * as FileSaver from 'file-saver';
import * as XLSX from 'xlsx';

const EXCEL_TYPE = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8';
const EXCEL_EXTENSION = '.xlsx';

@Injectable()
export class ExportexcelService {

  constructor() { }

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

表中的数据包含日期，货币行，此代码有效，但输出的日期和数字格式不正确。

注意：数据的代码采用json格式，我称之为data：Interfacename [];。该接口仅包含我的变量的名称，例如：

• 名称：字符串；
• lastname：string;
• age：number;
• 等...
