Frequently asked questions
Is the JSON to XML converter free?
Yes, it is completely free with no sign-up and no usage caps.
Is my data uploaded during conversion?
No. The conversion runs 100% in your browser, so your JSON and the XML it produces never touch our servers.
How are JSON keys mapped to XML?
Each JSON key becomes an XML element and nested objects become nested elements. Arrays are emitted as repeated elements, and the output is wrapped in a single root element so it is always well-formed.
Why did my conversion fail?
The converter validates the JSON first, so the usual cause is invalid JSON (a trailing comma or a missing bracket). Also note that JSON keys with characters that are illegal in XML element names need adjusting; the error message tells you which key.
Is there a size limit?
No hard limit. Everything runs locally, so the constraint is just your device’s memory; typical documents convert instantly.
How do I host the XML output?
Click Publish and the generated .xml file goes live at its own HTTPS link in seconds, with no server or build step required.
