# Importing to models

In case you want to import a workbook to an Eloquent model, you can use the ToModel concern. The concern enforces a model() method which accepts a model to be returned.

namespace App\Imports;

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

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

The returned model will be saved for you. Each row will result into (at least) one save and will also fire model events.

When using ToModel you should never save the model yourself, as that will break the batch insert functionality. If you need this, consider using OnEachRow.

# Skipping rows

In case you want to skip a row, you can return null.

public function model(array $row)
{
    if (!isset($row[0])) {
        return null;
    }

    return new User([
        'name' => $row[0],
    ]);
}

# Possible column names

In case you want to import rows by several possible column names (using WithHeadingRow), you can use null coalescing operator (??). If the column with the first name (in example client_name) exists and is not NULL, return its value; otherwise look for second possible name (in example client) etc.

public function model(array $row) {
  return new User([
    'name' => $row['client_name'] ?? $row['client'] ?? $row['name'] ?? null
  ]);
}

# Handling persistence on your own

In some cases you might not have an import in which each row is an Eloquent model and you want more control over what happens. In those cases you can use the OnEachRow concern.

namespace App\Imports;

use App\Group;
use App\User;
use Maatwebsite\Excel\Row;
use Maatwebsite\Excel\Concerns\OnEachRow;

class UsersImport implements OnEachRow
{
    public function onRow(Row $row)
    {
        $rowIndex = $row->getIndex();
        $row      = $row->toArray();
        
        $group = Group::firstOrCreate([
            'name' => $row[1],
        ]);
    
        $group->users()->create([
            'name' => $row[0],
        ]);
    }
}

When using OnEachRow you cannot use batch inserts, as the the model is already persisted in the onRow method.
