How to use JSON ↔ YAML Converter

Paste a JSON document and click Convert to YAML, or paste YAML and click Convert to JSON. The tool preserves structure and data types, and you can copy the output directly into your configuration files or source code.

Common use cases

DevOps engineers use this to convert Kubernetes manifests and Helm values between JSON and YAML as needed by different tools. Backend developers use it to adapt configs when migrating between services that expect different formats, and developers use it when working with OpenAPI specs in both formats.

Why run this in your browser?

All processing happens locally in your browser. Your data never leaves your machine, making it safe for sensitive payloads, internal API responses, and confidential configurations.
