JSON to YAML & CSV Converter
Convert structured JSON into YAML (for configuration files) or CSV (for spreadsheets). CSV mode requires a JSON array of flat objects.
YAML at a glance
YAML (Yet Another Markup Language) is a human-friendly data serialization standard widely used for configuration — Kubernetes, GitHub Actions, Docker Compose, Ansible. Where JSON uses braces and brackets, YAML uses indentation and dashes.
CSV at a glance
Comma-separated values is the lowest-common-denominator tabular format. It carries no type information, no schema, and limited support for nested data — which is why this tool flattens nested values into JSON strings inside their cells. CSV is ideal for spreadsheets and quick imports into databases.
CSV expects an array of objects. Provide a JSON array whose elements are flat objects with the same keys. Anything else won't convert cleanly.
