Steps
Follow these steps in the tool.
- Open XML to JSON and upload a file or paste XML.
- Review the JSON preview.
- Select Convert to JSON, then Copy JSON or Download JSON.
Security checks first
DOCTYPE declarations are rejected. Only UTF-8 is accepted. Nesting deeper than 50 levels fails with a clear error.
Mapping overview
Attributes go under @attributes. Repeated sibling names become arrays. Text-only elements become strings. Mixed content uses #text when needed.
