Frequently Asked Questions
Common questions about this tool.
How does JSON to XML conversion work? ▼
The converter maps JSON object keys into XML element tags (`<key>value</key>`) and JSON array elements into repeating sibling XML nodes under a parent container element.
Can I convert XML markup back to JSON? ▼
Yes! Toggle the direction selector in the workbench header to convert XML markup into structured JSON objects.
How are JSON array items converted to XML tags? ▼
JSON array items are mapped to repeating element tags. For example, `"items": ["a", "b"]` converts to `<items><item>a</item><item>b</item></items>`.
Are XML attributes supported during conversion? ▼
Yes. Properties prefixed with `@` (e.g., `"@id": "101"`) are automatically mapped as XML element attributes (`<element id="101">`).
Is client-side JSON to XML conversion private? ▼
Yes, 100%. All XML serialization and parsing logic runs locally in browser JavaScript memory. Zero byte data is sent over the network.
