JSON ↔ YAML Converter
Convert between JSON and YAML directly in your browser. Paste JSON or YAML on the left and get the converted result on the right. No data is sent to any server, which makes this tool safe for configuration, infrastructure and application data.
This converter is useful when working with Kubernetes manifests, Terraform variables, CI pipelines and any workflow where you need to switch between JSON and YAML formats quickly.
How to use the JSON and YAML converter
Choose the direction you want to convert at the top. For JSON to YAML, paste valid JSON into the input box and select Convert to produce YAML output. For YAML to JSON, paste YAML and convert it into formatted JSON with indentation.
Common questions
What are typical uses for JSON ↔ YAML conversion?
The converter is useful when working with Kubernetes manifests, Docker Compose files, CI configuration, Terraform variables or any system that can accept either JSON or YAML. It helps keep configs in sync across tools.
Is my JSON or YAML data stored?
No. All conversion is done with JavaScript in your browser. The data you paste never leaves your device.
Why does YAML convert to JSON with quotes and braces?
YAML is a superset of JSON, so when it is converted the tool produces valid JSON with braces, brackets and quotes. This output is safe to use in APIs, configuration files or scripts that expect JSON.
