How JSON ↔ YAML Conversion Works
JSON (RFC 8259) is a strict key-value format using double quotes, disallowing comments and trailing commas.
YAML 1.2 is indentation-based, supports comments, and is designed for human readability.
All JSON is valid YAML, but YAML → JSON may lose anchors, aliases, or tags due to format differences.
The converter parses input, validates syntax, and serializes output while preserving structure.
Frequently Asked Questions
Q.Are YAML comments preserved when converting to JSON?
A. No. YAML comments are removed during conversion because JSON does not support comments per RFC 8259.
Q.Can all YAML be converted to JSON?
A. Most YAML converts cleanly, but anchors (&), aliases (*), tags (!), and multi-document structures may not be preserved since JSON lacks equivalents.
Q.What’s the difference between JSON and YAML?
A. JSON is strict, structured, and machine-friendly; YAML is indentation-based and human-friendly. Use JSON for APIs/automation and YAML for configuration files.
Q.Can this converter handle large files?
A. Yes, within browser memory limits. Typical config files convert instantly; for files larger than several MB, use Manual mode for better performance.
