What YAML ↔ JSON does
Convert everyday mappings, arrays, booleans, numbers, and strings between YAML and JSON. The converter identifies the input format automatically.
Common uses
- Prepare YAML for a JSON-only API
- Inspect configuration as a JSON tree
- Generate readable YAML from JSON
Privacy and limitations
Conversion happens locally. Complex YAML anchors and custom tags require a full YAML engine.
Always validate security-sensitive output in the authoritative application or platform.
Frequently asked questions
Will comments be preserved?
No. JSON has no comment representation, so conversion cannot retain YAML comments.
Can it convert multiple YAML documents?
The first version focuses on a single common YAML document.
