Built for real config files
YAML powers Kubernetes manifests, GitHub Actions, GitLab CI, Ansible playbooks, and Docker Compose. This converter produces idiomatic output: minimal quoting so values stay clean, correct quoting when a string could be misread as a number or boolean, and literal block scalars for multiline text. Choose 2- or 4-space indentation to match your project's style.

FAQ
JSON to YAML, answered.
How do I convert JSON to YAML online?+
Paste your JSON into the converter above and press Convert to YAML. The tool emits clean, indented YAML you can use in config files, Docker Compose, Kubernetes manifests, and CI pipelines. Copy it or download a .yaml file. Everything runs in your browser.
Can I choose the indentation and quoting?+
Yes. Pick 2 or 4 spaces of indentation, and a quote style: Minimal quotes only when a value needs it, Single wraps strings in single quotes, and Double uses double quotes. Minimal produces the cleanest, most idiomatic YAML.
How are multiline strings handled?+
Multiline strings are emitted as YAML literal block scalars (the | style), which preserve line breaks and stay readable — instead of being escaped onto a single line.
Why convert JSON to YAML?+
YAML is the configuration language of DevOps — Kubernetes, GitHub Actions, GitLab CI, Ansible, and Docker Compose all use it. Converting a JSON config or API response to YAML makes it easier to read and edit by hand.
Is my data private?+
Yes. The conversion is 100% client-side, so your JSON is never uploaded or stored. It is safe for secrets, configuration, and private data, and there is no file-size cap.
