How to convert JSON to YAML

Paste your JSON on the left, or YAML on the right, and click the respective conversion button. The conversion is performed client-side using a highly reliable JavaScript YAML parser.

JSON vs YAML for Configuration Files

While JSON is the standard for API payloads and data interchange, YAML has become the dominant language for configuration files (like Docker Compose, Kubernetes manifests, and CI/CD pipelines). YAML is significantly more human-readable, allows comments, and relies on indentation rather than braces.

Secure Offline Parsing

Translating massive configuration files or database dumps between JSON and YAML can be tedious. This tool leverages the industry-standard js-yaml library right in your browser. This means you can safely convert proprietary server configurations without exposing them to third-party APIs.
