    {
        return Excel::download(new ExportUsers, 'users.xlsx');
    }

    public function import()

    *
    * @return \Illuminate\Database\Eloquent\Model|null
    */
    public function model(array $row)
    {
        return new User([
            'name'     => $row[0],
            'email'    => $row[1],
        ]);
    }
}

Step 8: Create Export Class

{
    /**
    * @return \Illuminate\Support\Collection
    */

    public function collection()
    {
        return User::all();
    }
}

Step 9: Create Blade File for View
