There is no canonical XML ⇄ JSON mappingwhy this tool asks you to chooseRead
XML has things JSON simply does not: attributes, comments, CDATA sections, processing instructions, namespaces, node order, and mixed text-and-element content. Every converter must choose what to keep, what to rename and what to throw away — which is why several competing conventions exist, and why this tool tells you exactly what each one loses on your document.
- Compact (fxp default) — the fast-xml-parser mapping: attributes become
@_namekeys, text becomes plain values, repeated elements become arrays. Readable and popular; loses order and comments. - BadgerFish — attributes become
@namekeys and element text moves into a$key, so text and attributes never collide. Verbose but unambiguous. - Parker — elements only: attributes are dropped entirely and the root element is absorbed. The cleanest JSON to consume, and the lossiest — this tool counts every attribute it discards.
- Round-trip faithful — an ordered node list that keeps comments, CDATA and processing instructions. Not pleasant to read, but it is the only convention from which the original XML can be rebuilt.
Rule of thumb: converting data (configs, API payloads, exports) — use Compact or Parker. Converting a document you need to reproduce — use Round-trip faithful.
