FAQ
How does JSON-to-XML conversion work?
Each JSON object becomes an XML element, each property becomes a child element, and each array becomes a series of repeated elements. Special keys prefixed with @ become attributes (e.g. {"@id": 1} → <root id="1">). The #text key sets an element's text content.
How are arrays handled?
Arrays become repeated sibling elements with a configurable item name. For example, {"items": [1,2,3]} with arrayItemName="item" becomes <items><item>1</item><item>2</item><item>3</item></items>.
Can I convert XML back to JSON?
Yes. The tool includes a reverse converter (XML → JSON) that turns attributes back into @-prefixed keys and reconstructs arrays from repeated elements. Round-trip fidelity is high for JSON-first data.
What extra features does this tool have?
10 extras: (1) XML validation (well-formedness check). (2) Copy output. (3) Download .xml file. (4) Reverse conversion (XML→JSON). (5) Custom namespace declaration on root. (6) Configurable attribute prefix (default @). (7) Configurable array item element name. (8) Depth limit (prevents runaway recursion). (9) History (localStorage — last 10 conversions). (10) Type info annotation (xsi:type-style hints) for primitives.
Is my JSON data uploaded anywhere?
No. All conversion happens in your browser using pure JavaScript. Your data never leaves your device.
What's the maximum input size?
There's no hard limit, but very large JSON (> 10MB) may slow the browser. A depth limit (default 100) prevents stack overflow on deeply nested input.
