JSON to YAML Converter
Turn JSON objects and arrays into indentation-based YAML while preserving primitive values. Strings that could be misread as numbers, booleans, null, dates, or YAML syntax are quoted.

Data handling notes
- Conversion runs locally and does not submit configuration data.
- Nested objects use two-space indentation.
- The converter produces practical YAML output but does not preserve JSON comments because JSON has none.
Before you rely on the result
This tool is intended for fast inspection and routine preparation. It can save time, but it does not replace review when the result affects production systems, security settings, business data, or legal obligations.
- Check representative inputs instead of assuming one example covers every edge case.
- Do not paste secrets, private customer data, or credentials unless you have confirmed the page processes that data locally and the use is allowed by your organization.
- Copy the output into your own workflow only after checking formatting, timezone, encoding, or syntax assumptions.
- Data conversion tools preserve structure where possible, but they cannot infer business rules such as optional fields, database dialects, XML namespaces, or CSV column meaning.
FAQ
Will strings like `true` stay strings?Yes. Ambiguous strings are quoted so YAML parsers do not change their type.
Can it convert YAML back to JSON?Not in this version; the page intentionally handles JSON-to-YAML only.
