About YAML ↔ JSON Converter

Convert YAML to JSON and JSON to YAML instantly. Essential for DevOps work where configuration moves between formats — Kubernetes manifests, Docker Compose files, CI/CD pipelines, Ansible playbooks, and Helm charts on one side; APIs and JavaScript tooling on the other.

Both directions validate your input and report parse errors, so the converter doubles as a quick YAML/JSON syntax checker. Everything runs locally in your browser.

Key Features

  • Two-way conversion: YAML → JSON and JSON → YAML
  • Validates input and surfaces parse errors
  • Great for Kubernetes, Docker Compose, and CI configs
  • Client-side only — configs never leave your machine

Frequently Asked Questions

What is the difference between YAML and JSON?

Both represent the same kinds of structured data. YAML is indentation-based and easier for humans to read and write (hence its use in config files), while JSON is stricter and universally supported by APIs and programming languages.

Will my data survive the conversion unchanged?

Values and structure are preserved in both directions. Note that YAML comments have no JSON equivalent, so they are dropped when converting YAML to JSON.

Is it safe to paste infrastructure configs here?

Yes. Conversion happens entirely in your browser — your manifests and configuration files are never uploaded or stored.
