# JSON to CSV sample

This is a small, dependency-free Python 3.10+ utility that converts a JSON
array of flat objects to CSV. It preserves the first-seen column order, fills
missing or `null` cells with an empty string, and rejects malformed or nested
input with a clear error.

## Run

```bash
python3 json_to_csv.py sample.json sample.csv
```

## Test

```bash
python3 -m pytest -q
```

The utility reads local files only. It has no accounts, network calls,
credentials, CAPTCHA bypass, production access, or cyber functionality.
