YAML ↔ JSON Converter — Free Two-Way Conversion

Convert YAML to JSON or JSON to YAML with a single click. YAML anchors and aliases are resolved before conversion so the output is always fully expanded and valid. Handy for working across Kubernetes configs, GitHub Actions workflows, and any tooling where one format is required but the source is in the other.

All processing happens in your browser. No data is sent to any server.

Frequently Asked Questions

Can it convert in both directions?
Yes. Switch between YAML→JSON and JSON→YAML. Both directions are fully supported.
Why would I convert YAML to JSON?
JSON is more widely supported by APIs and configuration parsers. Converting YAML to JSON makes the data portable to any tool that expects JSON input.
Does it handle anchors and aliases in YAML?
Yes. YAML anchors (&) and aliases (*) are resolved before conversion, so the JSON output contains the fully expanded values.
