JSON to YAML
Convert JSON data to YAML format.
About JSON to YAML
JSON to YAML converts your JSON document into YAML, which is often preferred for configuration files because it is less verbose and easier for humans to read and edit. YAML is the native format for Kubernetes manifests, GitHub Actions workflows, Docker Compose files, and many other DevOps tools. The conversion is lossless — all data types and structures are preserved.

Frequently Asked Questions
Is JSON to YAML free?
Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.
Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
Is the YAML output valid and ready to use in Kubernetes or Docker Compose?
Yes, the output is standard YAML. You may want to run it through the YAML Formatter afterwards to fine-tune indentation to your project conventions.
Are JSON null values and booleans preserved correctly?
Yes. JSON null maps to YAML null, true/false map to YAML true/false, and numbers retain their type.
