JSON to YAML Converter

Paste any JSON document and get a valid YAML representation in return. The converter maps objects, arrays, strings, numbers and booleans to YAML with correct two-space indentation, quotes values that need escaping and keeps nested structures readable. Everything runs in your browser, so config files and API payloads never leave your machine.

Quick Answers

Is this JSON to YAML converter safe for configuration files?
Yes. All conversion happens locally in your browser. Your JSON is never uploaded, stored or transmitted, which makes it safe for private configs, tokens and CI secrets.
Does it handle nested objects and arrays?
Yes. Objects and arrays are converted recursively. Lists of objects become YAML block sequences with proper indentation, and nested maps are emitted with two-space indentation.
Can I convert the YAML back to JSON?
Yes. Use the companion YAML to JSON converter on this site. The two tools work the whole pipeline with no data leaving your browser.

Why use our json to yaml converter?

This JSON to YAML converter is built for developers and DevOps engineers who work with Kubernetes, Docker Compose, GitHub Actions and other YAML-based files but prefer to author in JSON. It automatically detects arrays of objects and emits the correct `- item` list syntax, preserves key order, and quotes scalar values that YAML would otherwise misinterpret (such as strings like `yes`, `123` or values with colons). Because conversion is fully client-side, secrets and configs stay confidential.
