Conversion rules
Objects map to YAML mappings, arrays to sequences, null to null.
Strings that could be misread as numbers, booleans or YAML syntax (colons, leading/trailing
spaces, special characters) are automatically double-quoted, so the output round-trips
back to identical JSON.
FAQ
Why is my string quoted?
Values like "123", "true", "yes" or strings containing : # [] must be quoted in YAML to stay strings. The converter quotes only when necessary.
Can I convert YAML back to JSON?
Full YAML parsing (anchors, multi-line scalars) requires a heavier parser — planned for a future YAML to JSON tool.
Is my data uploaded?
No. Conversion runs entirely in your browser.
