 
                We can generate excel files using PHPExcel, but with laravel its super easy to generate.
We need one package for that.
Step 1 : Install Package
run below command in your terminal
composer require maatwebsite/excelStep 2 : Add Provider & Alias
we need to add service provide & alias in our project config file which located following path : config/app.php
<?php
return [
   "providers" => [
       Maatwebsite\Excel\ExcelServiceProvider::class,
   ],
   "aliases"   => [
       "Excel" => Maatwebsite\Excel\Facades\Excel::class,
   ],
];Step 3 : Create Export class
Create export class for excel which manage excel properties, views, etc.
Create class in following path : /app/Exports/Export.php
& we will create method which return view of excel.
<?php
namespace App\Exports;
use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;
class Export implements FromView {
   public function view(): View {
       return view("/exports/excel");
   }
}Step 4 : Create View
Create blade file with your preferred location.
For best practice we will manage excel & it's cells with HTML table row & column format.
for example :
<table>
   <tr>
       <td>Sr. No.</td>
   </tr>
   <tr>
       <td>1</td>
   </tr>
</table>Step 5 : Call Export class in method
Now call export class in your method of controller.
Class will return excel file to download.
<?php
namespace App\Http\Controllers;
use App\Exports\Export;
use App\Http\Controllers\Controller;
use Excel;
use Illuminate\Http\Request;
class PoleSurveyController extends Controller {
   public function export(Request $_request) {
       return Excel::download(new Export);
   }
}
