XML ↔ JSON Converter
Paste or upload XML or JSON, choose a direction, and convert. Everything runs locally in your browser — nothing is uploaded.
How it works
XML is parsed and built entirely in your browser using fast-xml-parser — nothing is sent to a server. Attributes become @_name properties, repeated sibling elements become arrays, and CDATA/comments are kept under their own #cdata/#comment keys.
XML and JSON are not a perfect 1:1 match, so this isn't a "lossless" round-trip tool: mixed text/element content loses its exact interleaving order, XML has no native number/boolean/null types (they come back from JSON as plain text), an empty JSON array has no XML equivalent and is dropped, and a single-item list becomes a plain value if converted back. DOCTYPE/DTD declarations are rejected outright rather than processed. JSON → XML requires an object with exactly one top-level property (the root element), with property names that are valid XML names.
