Safe conversion between JSON, YAML, and XML
A round-trip workflow that compares parsed structures and documents information that cannot be represented in the destination format.
JSON, YAML, and XML do not share one identical data model. A visually plausible conversion can silently change types, namespaces, repeated elements, comments, or whitespace.
Define the mapping before conversion
Decide how XML attributes, text, namespaces, repeated elements, and empty nodes map to objects and arrays. For YAML, review anchors, tags, multi-document files, and implicit scalar typing.
Protect ambiguous scalar values
Test null, booleans, leading zeros, large numbers, dates, binary data, and empty strings. Quote values when a YAML parser might infer an unwanted type.
Validate the round trip
Parse source and result, compare their normalized structures, validate against schemas where available, and preserve the original when comments or exact XML whitespace matter.
Structured data conversion checklist
- Document the source and destination mapping
- Test ambiguous scalar types
- Review arrays attributes and namespaces
- Compare parsed structures after conversion
- Preserve information with no target equivalent
