JSON <-> YAML Converter

Paste JSON or YAML into the input. The tool auto-detects the format and converts it to the other one. All parsing and conversion happens in your browser.

  • Convert JSON <-> YAML with auto-detection.
  • Copy or download the converted output.
  • Useful for Kubernetes configs and API specs.
  • Share results: Generate a secure link to share your current input and results with teammates — nothing is uploaded to any server.

i If the input parses as JSON, it will be treated as JSON -> YAML. Otherwise, the tool tries YAML -> JSON.

YAML streams with multiple documents convert to a JSON array by default.

JSON side is ideal for API payloads and configs; YAML side is handy for Kubernetes manifests, CI/CD pipelines and infra-as-code files.

How to use the JSON ↔ YAML Converter

Convert JSON to YAML and YAML back to JSON for Kubernetes manifests, Helm values, OpenAPI specs, GitHub Actions workflows, Ansible playbooks, and Docker Compose files. The converter auto-detects the input direction, preserves data types and ordering, and produces output that round-trips cleanly. All conversion runs locally in your browser; configs never leave your machine.

What it does

When to use it

How to use it

  1. Paste your JSON or YAML into the input editor (or load from clipboard / file).
  2. The tool auto-detects the input format and shows the converted output side by side.
  3. Toggle the conversion direction explicitly if you want to force JSON → YAML or YAML → JSON.
  4. Pick indentation (2 or 4 spaces) for YAML output.
  5. Copy or download the result. For Kubernetes, paste the YAML back into your manifest file.
  6. Run the output through the YAML Validator or JSON Formatter for a final syntax pass.
