Home › Developer Tools › JSON to YAML Converter
Paste JSON and get nicely indented YAML — the format used by Kubernetes, Docker Compose, GitHub Actions and most modern config files. Strings that YAML would misread are quoted automatically. Runs in your browser.
YAML reads some plain strings as other types: yes, no, on, off, numbers and null. To keep your strings as strings, this converter quotes the risky ones (for example a country code "NO" or a version "1.20"). Two-space indentation is used throughout, matching most tooling.
Mostly — valid JSON is valid YAML, but YAML adds comments, anchors and multi-line strings that JSON does not have.
YAML is whitespace-sensitive. Copy with a plain-text editor to avoid smart-quote or tab substitutions.
