JSON to YAML

Convert API JSON into human-friendly config with this free JSON to YAML converter. Paste a JSON object or array, choose indent size, and get YAML suitable for Kubernetes, Ansible, or app settings - all without uploading your payload.

Developers often keep source-of-truth as JSON in tests and publish YAML for ops. This client-side tool bridges that gap instantly and pairs with our YAML validator for a quick sanity check after hand edits.

Frequently Asked Questions

Will comments in JSON survive?
Input may include JSONC comments for convenience, but YAML output is generated from the data model - comments are not preserved.
How are null and empty values handled?
JSON null becomes YAML null. Empty objects/arrays are emitted as {} and [] respectively depending on the dumper.
Is the conversion lossless?
For ordinary JSON data types, yes. Exotic number edge cases (beyond IEEE doubles) follow JavaScript number rules.
Can I go back to JSON?
Use the YAML to JSON tool to round-trip after edits.
