# A lone { stops at column 2

A single opening brace stops at column 2. The converter shows `Expected property name or '}' in JSON at position 1 (line 1 column 2)`, and the output is cleared. An empty text box is the third of these failures: `Unexpected end of JSON input`. The characters that were there before the failed parse are gone.

The paste people usually mean is the trailing comma.

```json
{"a":1,}
```

That one reports `Expected double-quoted property name in JSON at position 7 (line 1 column 8)`. The comma asks for another key. The `}` is what the parser finds instead. All three of these are parse errors. The page copies that message and leaves the result blank. Parsing stays in the browser.

`[]` is allowed JSON, so it does not take that path. Laravel prints `[]`. TypeScript drafts this:

```ts
export interface Root {

}
```

The PHP class is still `DataTransferObject`. It has `declare(strict_types=1)`, no fields, and a constructor with an empty body. CSV rejects the empty array with `CSV conversion expects an array of objects.`

Take the comma out in the [JSON formatter](https://kepttools.com/json-formatter) and run the [JSON converter](https://kepttools.com/json-converter) again.

The sample object and the other limits are in the guide: <https://kepttools.com/guides/json-to-typescript-php-dto-laravel>
