Waiting for JSON.
JSON to XML Converter
Turn JSON into deterministic XML locally
Convert nested data, configure root and array-item names, and copy or download XML without uploading the source.
No conversion yet
Conversion runs entirely in this browser.
Deterministic mapping
Predictable XML for every JSON value
Object keys become child elements. Arrays become repeated configurable item elements. Strings, numbers and booleans become text. Null becomes an empty element with type="null".
Safe element names
Names that are not safe XML element names are mapped deterministically and reported as clear warnings. Collisions receive numeric suffixes.
Purposeful conversion
Formatted or compact output
Choose readable indentation or compact XML, then copy the complete result or download an .xml file.
Not a lossless round trip
XML and JSON have different data models. The mapping is documented and deterministic, but converting the XML back cannot be assumed to reproduce the original JSON exactly.
FAQs
JSON-to-XML questions
What happens to top-level arrays?
The configured root wraps repeated array-item elements, using item by default.
Does the converter upload JSON?
No. File reading, parsing and XML generation happen locally in your browser.
