        return Users::whereYear('created_at', $this->year)->get();
    }
}
```

--------------------------------

### Export with Multiple Sheets

Source: https://docs.laravel-excel.com/3.1/exports/multiple-sheets.html

Implement `WithMultipleSheets` to create an Excel file with multiple sheets. The `sheets()` method should return an array of sheet export objects. This example iterates through months to create a sheet for each.

```php
namespace App\Exports;

use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;

class InvoicesExport implements WithMultipleSheets
{
    use Exportable;

    protected $year;
    
    public function __construct(int $year)
    {
        $this->year = $year;
    }

    /**
     * @return array
     */
    public function sheets(): array
    {
        $sheets = [];

        for ($month = 1; $month <= 12; $month++) {
            $sheets[] = new InvoicesPerMonthSheet($this->year, $month);

namespace App\Imports;

use App\User;
use Maatwebsite\Excel\Concerns\ToModel;
use Illuminate\Contracts\Queue\ShouldQueue;
use Maatwebsite\Excel\Concerns\WithChunkReading;

class UsersImport implements ToModel, WithChunkReading, ShouldQueue
{
    public function model(array $row)
    {
        return new User([
            'name' => $row[0],
        ]);
    }

    public function chunkSize(): int

```php
Excel::import(new UsersImport, 'users.xlsx');
```

--------------------------------

### Define User Import Logic with ToModel

Source: https://docs.laravel-excel.com/3.1/imports/basics.html

Implement the `ToModel` concern to map each row of the Excel file to a Eloquent model. Ensure necessary facades like `Hash` are imported.

```php
<?php

namespace App\Imports;

use App\Models\User;
use Illuminate\Support\Facades\Hash;
use Maatwebsite\Excel\Concerns\ToModel;

class UsersImport implements ToModel
{
    /**
     * @param array $row
     *
     * @return User|null
     */
    public function model(array $row)
    {
        return new User([
           'name'     => $row[0],
           'email'    => $row[1],
           'password' => Hash::make($row[2]),
        ]);
    }
}
```

--------------------------------

### Handling Import Failures with Events

Source: https://docs.laravel-excel.com/3.1/imports/queued.html

Implement `WithEvents` and listen for the `ImportFailed` event to handle failures in queued imports. This allows you to notify users or perform other actions when an import fails.

```php
namespace App\Imports;

use App\User;
use App\Notifications\ImportHasFailedNotification;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\ImportFailed;
use Illuminate\Contracts\Queue\ShouldQueue;
use Maatwebsite\Excel\Concerns\WithChunkReading;

class UsersImport implements ToModel, WithChunkReading, ShouldQueue, WithEvents
{
    public function __construct(User $importedBy)
    {
        $this->importedBy = $importedBy;
    }

    public function registerEvents(): array
    {
        return [
            ImportFailed::class => function(ImportFailed $event) {
                $this->importedBy->notify(new ImportHasFailedNotification);
            },
        ];
    }
}

```

--------------------------------

```

--------------------------------

### Combine Chunk Reading with Batch Inserts

Source: https://docs.laravel-excel.com/3.1/imports/chunk-reading.html

For optimal performance, combine `WithChunkReading` with `WithBatchInserts`. This approach minimizes both time and memory consumption by processing data in batches and chunks. Configure both `batchSize` and `chunkSize` methods.

```php
namespace App\Imports;

use App\User;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithBatchInserts;
use Maatwebsite\Excel\Concerns\WithChunkReading;

class UsersImport implements ToModel, WithBatchInserts, WithChunkReading
{
    public function model(array $row)
    {
        return new User([
            'name' => $row[0],
        ]);
    }
    
    public function batchSize(): int
    {
        return 1000;
    }
    
    public function chunkSize(): int
    {
        return 1000;
    }
}
```

--------------------------------

### Use Import with Progress Bar in Console Command

Source: https://docs.laravel-excel.com/3.1/imports/progress-bar.html

```php
<?php

namespace App\Console\Commands;

use App\Imports\UsersImport;
use Illuminate\Console\Command;

class ImportExcel extends Command
{
    protected $signature = 'import:excel';

    protected $description = 'Laravel Excel importer';

    public function handle()
    {
        $this->output->title('Starting import');
        (new UsersImport)->withOutput($this->output)->import('users.xlsx');
        $this->output->success('Import successful');
    }
}

```

--------------------------------

### Forcing Remote Temporary File Resync in Multi-Server Setups

Source: https://docs.laravel-excel.com/3.1/imports/queued.html

Enable `force_resync_remote` to true in the configuration to ensure local temporary files are deleted on each server after its processed chunk. This prevents storage limits from being exceeded in multi-server environments.

```php
'temporary_files' => [
    'force_resync_remote' => true,
],

```

--------------------------------

### Basic Queued Export

Source: https://docs.laravel-excel.com/3.1/exports/queued.html

Queue an export process by calling the `queue()` method on an export instance. This is suitable for large datasets that may take a long time to process.

```php
namespace App\Exports;

use App\Invoice;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\FromQuery;

class InvoicesExport implements FromQuery
{
    use Exportable;

    public function query()
    {
        return Invoice::query();
    }
}

```

```php
(new InvoicesExport)->queue('invoices.xlsx');

return back()->withSuccess('Export started!');

```

--------------------------------

### Manual UsersImport Class Implementation

Source: https://docs.laravel-excel.com/3.1/imports

Manually create this `UsersImport` class in `app/Imports`. It implements the `ToModel` concern to map rows from the Excel file to `User` model instances, hashing the password.

```php
<?php

namespace App\Imports;

use App\Models\User;
use Illuminate\Support\Facades\Hash;
use Maatwebsite\Excel\Concerns\ToModel;

class UsersImport implements ToModel
{
    /**
     * @param array $row
     *
     * @return User|null
     */
    public function model(array $row)
    {
        return new User([
           'name'     => $row[0],
           'email'    => $row[1], 
           'password' => Hash::make($row[2]),
        ]);
    }
}
```

--------------------------------

### Apply Custom Macro and Set Page Orientation in AfterSheet Event

namespace App\Exports;

use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\BeforeExport;
use Maatwebsite\Excel\Events\AfterSheet;

class InvoicesExport implements WithEvents
{
    /**
     * @return array
     */
    public function registerEvents(): array
    {
        return [
            BeforeExport::class  => function(BeforeExport $event) {
                $event->writer->setCreator('Patrick');
            },
            AfterSheet::class    => function(AfterSheet $event) {
                $event->sheet->setOrientation(\PhpOffice\PhpSpreadsheet\Worksheet\PageSetup::ORIENTATION_LANDSCAPE);
