YAML to JSON and JSON to YAML Converter

Convert YAML configuration files to JSON and JSON back to YAML locally with indentation, key sorting, and downloadable output.

What This Tool Does

This browser-based converter parses YAML into structured data, exports readable JSON, and converts JSON objects or arrays back into YAML. It is useful for config files, API fixtures, CI examples, and developer documentation.

Common Use Cases

  • Converting YAML configuration files into JSON for APIs, tests, or tooling
  • Turning JSON examples back into YAML for documentation, CI, Kubernetes, or app config snippets
  • Checking YAML or JSON syntax and normalizing indentation before sharing

How Data Is Handled

YAML and JSON conversion runs locally in your browser. Your configuration text and data are not uploaded to the backend.

FAQ

Is my YAML or JSON uploaded?

No. Parsing and conversion run locally in your browser.

Can it convert JSON arrays and nested objects?

Yes. Arrays, nested objects, strings, numbers, booleans, and null values are supported.

Does it preserve comments from YAML?

No. The converter focuses on data conversion, so YAML comments are not preserved in JSON output.
