Command :

<?php

namespace App\Console\Commands;

use App\Imports\ContractsImport;
use Illuminate\Console\Command;
use Maatwebsite\Excel\Facades\Excel;

class ImportContracts extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'import:contracts';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Import contracts from XLSX file';

    /**
     * Execute the console command.
     */
    public function handle()
    {
        $file = storage_path('app/import/contrats.xlsx');

        if (! file_exists($file)) {
            $this->error("The file {$file} does not exist.");

            return;
        }

        $this->info("Importing contracts from {$file}");

        try {
            $import = new ContractsImport();
            $import->onlySheets('SUIVI ENTRETIEN '.date('Y'));

            Excel::import($import, $file);

            $this->info('Import completed successfully.');
        } catch (\Exception $e) {
            dump($e);
            $this->error('An error occurred during import: '.$e->getMessage());
        }

            ], [
              ...
            ]);

            $updated++;
        }

        dump($updated.' updated, '.$ignored.' ignored');
    }

    public function startRow(): int
