Convert JSON to YAML
JSON is great for machines, but YAML is far easier for humans to read and edit, which is why it dominates config files, CI pipelines, and Kubernetes manifests. This converter rewrites your JSON into clean, indented YAML and updates the output live as you type or paste. Nothing is uploaded — the conversion runs instantly in your browser.
Paste your JSON on the left and pick YAML on the right.
Why convert JSON to YAML?
- YAML's indentation-based syntax is cleaner for config files than JSON's brackets and quotes.
- Most CI/CD tools (GitHub Actions, GitLab CI) and Kubernetes manifests expect YAML, not JSON.
- YAML supports comments, so you can document config that plain JSON could never annotate.
- Live, in-browser conversion means no upload and instant feedback as you edit.
How to convert JSON to YAML
- 1Paste your JSON into the left-hand editor.
- 2Set From = JSON and To = YAML.
- 3Watch the YAML appear on the right, updating live as you type.
- 4Copy the converted YAML. Everything runs in your browser, nothing is uploaded.
Frequently asked questions
Is the converted YAML still valid for my JSON data?+
Yes. YAML is a superset of JSON, so every JSON structure has an equivalent YAML representation. The keys, values, arrays, and nesting are preserved exactly.
Can I convert YAML back to JSON?+
Yes. The same tool converts both directions — just swap the From and To settings to turn YAML back into JSON.
Will it keep my nested objects and arrays?+
It does. Nested objects become indented YAML blocks and arrays become dash-prefixed lists, so the full hierarchy of your JSON is retained.
