❓ Frequently Asked Questions

Does YAML to JSON conversion lose data?
No. YAML is a superset of JSON, so all YAML data can be converted to JSON losslessly. However, YAML-specific features like comments, multi-line strings, anchors, and aliases have no JSON equivalent and will be dropped during conversion.
Are YAML comments preserved in JSON?
No. JSON format doesn't support comments, so YAML comments are dropped during conversion. If you need to keep comments, stay with YAML format.
Which YAML features need attention during conversion?
1) YAML anchors (&) and aliases (*) are expanded to actual values; 2) Date/time types become strings; 3) Integers and floats maintain their types; 4) Null values become JSON null.
Does this tool support complex YAML files?
Yes. It handles standard YAML 1.2 including nested objects, arrays, multi-line strings, booleans, and numeric types. Recommended file size: up to 5MB.
Which is better for API data exchange - JSON or YAML?
JSON is the industry standard for API data exchange. YAML is better for human-readable config files. Converting YAML API data to JSON makes it easier to process in JavaScript and other programming languages.
