<?php

0) Install Laravel Excell
composer require maatwebsite/excel

1) create Export Controller:
php artisan make:export RegistrationsExport --model=Registration

2) Generated Export Class will look like:

namespace App\Exports;

use App\Registration;
use Maatwebsite\Excel\Concerns\FromCollection;

class RegistrationsExport implements FromCollection
{
  /**
  * @return \Illuminate\Support\Collection
  */
  public function collection()
  {
    return Registration::all();
  }
}


3) RegistrationsController export method:
    /*
    |---------------------------
    | EXCEL EXPORT DEFAULT TABLE
    |---------------------------
    */
    public function export() {
        return Excel::download( new RegistrationsExport(), 'registrations.xlsx') ;
    } 


5) in web.php
    Route::get('registrations/export', 'RegistrationsController@export')->name('registrations.export') ;



6) In Blade View
<a href="{{ route('registrations.export') }}" class="btn btn-dark fright">Export all Registrations <i class="fas fa-download"></a>
