SparkJSONJSON to XML Converter
Map JSON objects to XML elements (not attributes). Arrays become repeated sibling tags with the same name. Output includes an XML declaration and a <root> wrapper.
Free SparkJSON tool — runs 100% in your browser. No signup, no upload, no paywall. This page converts JSON to XML locally.

XML can store data as attributes (@id="1") or child elements (<id>1</id>). SparkJSON uses element mapping for every field. That keeps the conversion predictable and avoids guessing which keys “look like” attributes.
If you need attributes for a specific schema (SOAP, industry XML), map them in a second step or a dedicated XSLT pipeline. This tool prioritizes a faithful, readable default.
Keys with spaces or odd symbols are sanitized to safe tag names (non [A-Za-z0-9_-. ] → _). Prefer clean keys in the JSON first.
Nothing is written as an attribute. Everything is an element so the mapping rule stays one sentence long.
Output is wrapped in <root> so fragments and arrays have a single document element.
["a","b"] → repeated <root> children named from the conversion rules
Not in this tool. Elements are always used. Export elements, then transform if your schema requires attributes.
As repeated sibling elements sharing the parent key name (or item/root naming when appropriate).
No. It runs client-side only.
