Frequently Asked Questions

What is an XML to JSON converter?
It transforms XML markup into a JSON object and converts JSON back into XML. Attributes map to keys with a configurable prefix and element text content uses a #text key.
How do I use the XML to JSON converter?
Choose a direction, paste your XML or JSON, and the converted output appears instantly. Use the Sample button to load an example or Swap to flip the conversion direction.
Is the XML to JSON converter free?
Yes. It works in your browser with no account and no request limits, so you can convert files as large as your browser can comfortably hold.
Does this converter store my data?
No. Parsing and serialization run locally using your browser's native DOMParser. Your XML and JSON never leave the page or reach a server.
How are attributes and repeated tags handled?
Attributes become keys prefixed with @ by default, which you can change. Repeated child elements that share a tag collapse into a JSON array automatically.
