How to convert YAML and JSON

Convert YAML config files to JSON (and back) in your browser with Toolora’s YAML ↔ JSON Converter.

When to convert

YAML is common in config and CI files; JSON is common in APIs and JavaScript apps. Converting between them helps when you need the same data in both formats.

YAML → JSON

1) Open YAML ↔ JSON Converter. 2) Choose YAML → JSON. 3) Paste your YAML. 4) Click Run and copy the formatted JSON.

JSON → YAML

Choose JSON → YAML, paste a JSON value, and run the tool. Nested objects and arrays are preserved in the YAML output.

Tips

Invalid YAML or JSON is rejected with an error before conversion. For CSV data, use the CSV ↔ JSON Converter instead.
