JSON and YAML Converter
Convert between JSON and YAML online
Convert JSON to YAML or YAML to JSON online with formatting, minification, syntax checks and file upload or download. Ideal for configs, Kubernetes and CI/CD.
Instructions
Basic usage
YAML is always on the left and JSON on the right. Use the center arrows to convert either way; both sides are editable.
Output options
Set indentation size for your config or API needs.
File workflow
Upload .json into the right panel or .yaml/.yml into the left. Each side supports format, minify, copy, and download.
Tips
- Use Format first when conversion fails due to syntax errors
- Use Sample content for quick testing
- Edit either side freely, then use the center arrows to sync YAML and JSON
