I am working in angular 8 project. I have one component which process some data & export this data to excel using XLSX.WorkSheet method. When i run my application in browser then it successfully download EXCEL file(.xlsx).

Now i am converting my angular 8 application to Cordova android, all functionality working same as brower view of my angular app but when i tring to Export EXCEL then file not downloading.

Here i show some code of angular project for Export Excel data as below

import { ExportAsService, ExportAsConfig, SupportedExtensions } from 'ngx-export-as';
import * as XLSX from 'xlsx';
constructor(private exportAsService: ExportAsService) {}

public exportExcel(jsonData: any[], fileName: string): void {
    const ws: XLSX.WorkSheet = XLSX.utils.json_to_sheet(jsonData);
    const wb: XLSX.WorkBook = { Sheets: { 'data': ws }, SheetNames: ['data'] };
    const excelBuffer: any = XLSX.write(wb, { bookType: 'xlsx', type: 'array' });
    var out = XLSX.write(wb, { type: 'base64' });
    var xlsContent = 'data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,' + out;
    this.exportAsService.downloadFromDataURL(fileName, xlsContent);    
}

Now i am converting my angular 8 application to Cordova android, all functionality working same as brower view of my angular app but when i try to Export EXCEL then file not downloading.

Here i show some code of angular project for Export Excel data as below.

import { ExportAsService, ExportAsConfig, SupportedExtensions } from 'ngx-export-as'; import * as XLSX from 'xlsx'; constructor(private exportAsService: ExportAsService) {}

public exportExcel(jsonData: any[], fileName: string): void { const ws: XLSX.WorkSheet = XLSX.utils.json_to_sheet(jsonData); const wb: XLSX.WorkBook = { Sheets: { 'data': ws }, SheetNames: ['data'] }; const excelBuffer: any = XLSX.write(wb, { bookType: 'xlsx', type: 'array' }); var out = XLSX.write(wb, { type: 'base64' }); var xlsContent = 'data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,' + out; this.exportAsService.downloadFromDataURL(fileName, xlsContent);
