    What this tool does

    Convert YAML ↔ JSON locally, including YAML streams with multiple documents separated by ---. This is useful for configs, CI pipelines, and debugging payloads without sending them to third-party converters.

    Common pitfalls

    YAML is indentation-sensitive. Tabs, inconsistent spaces, and duplicate keys can break parsing. If your conversion fails, normalize indentation and validate the structure first.
