Online XML Generator

Paste JSON and generate clean XML instantly. Everything runs locally in your browser—no uploads. Supports attributes via @attr keys and text nodes via #text.

Category: Developer · URL: /tools/online-xml-generator.html
JSON conventions: keys starting with @ become attributes (e.g., {"user":{"@id":"7","name":"Ada"}}), and #text becomes the element text node.
Tip: for arrays of objects, each item becomes <item>...</item> (or your chosen Array item tag).
If you need formatting/validation/XPath on existing XML, use: XML Tools (Online Alternative).
Privacy: runs locally in your browser. No uploads, no tracking scripts.

FAQ

What input does this XML generator accept?

It accepts valid JSON (object or array) and converts it into XML under your chosen root tag.

How do I add XML attributes in the JSON?

Use keys that start with @, for example {"user":{"@id":"7","name":"Ada"}}<user id="7">...</user>.

How are JSON arrays converted to XML?

Arrays become repeated elements using the Array item tag (default: item) inside the array’s property element.

Can I generate minified XML?

Yes—uncheck Pretty to generate compact XML without indentation and extra whitespace.

Does this validate my XML against an XSD?

No—this tool generates XML. For validation/formatting/XPath workflows, use the XML tools page linked under the output.

What if my JSON keys aren’t valid XML tag names?

The tool sanitizes keys by replacing invalid characters with underscores and ensuring the name starts with a valid character.

Is my data sent to a server?

No. Generation runs locally in your browser; the tool does not make network requests.
