# The name cell on row 2 is empty

The name column on row 2 is blank. This array gives `name` to the first object and `email` to the second, and the CSV writer still emits one header from every top-level key.

```csv
id,name,email
1,Ada,
2,,linus@example.com
```

Read `1,Ada,` as id 1, name Ada, and an empty email. Read `2,,linus@example.com` as id 2, an empty name, and that email address. The comma with nothing between it and the next comma is the empty cell.

Laravel does print the second object, so `email` survives there as a quoted key.

```php
[
    [
        'id' => 1,
        'name' => 'Ada',
    ],
    [
        'id' => 2,
        'email' => 'linus@example.com',
    ],
]
```

The TypeScript interface and the PHP class are a different cut. With an array at the root, both are taken from the first object, `{"id":1,"name":"Ada"}`. `Root` lists `id` and `name`. `email` is not a field on that interface, and it is not a property on the class.

```ts
export interface Root {
  id: number;
  name: string;
}
```

```php
<?php

declare(strict_types=1);

class DataTransferObject
{
    public int $id;
    public string $name;

    public function __construct(array $data = [])
    {
        $this->id = $data['id'] ?? null;
        $this->name = $data['name'] ?? null;
    }
}
```

Those two assignments are the whole constructor. Parsing and the four conversions stay in the browser. The [JSON converter](https://kepttools.com/json-converter) does not send the paste to an API.

The sample with `meta`, and the questions beside it, are in the guide: <https://kepttools.com/guides/json-to-typescript-php-dto-laravel>
