About This Tool
Convert a JSON object to clean YAML output. Preserves nested structures, arrays, and all JSON data types.
Optional key sorting for deterministic output. Uses PyYAML's safe_dump to avoid generating YAML tags or anchors.
Why Use This Tool
- Config Generation — Generate YAML configuration files (Kubernetes, Docker Compose, CI/CD) from JSON data.
- Documentation — Convert JSON examples to more readable YAML format for documentation.
Frequently Asked Questions
Are YAML anchors/aliases generated?
No — safe_dump produces plain YAML without anchors, aliases, or custom tags.
What about multi-line strings?
Long strings are automatically formatted with YAML's literal block scalar (|) style.
