Instructions
What this tool does
This tool converts data between JSON and XML, useful for API debugging, config migration, and data exchange.
How to use
- JSON is on the left and XML on the right; use the center arrows to convert either way. Both panels are editable.
- Upload .json or .xml per panel, or load a sample from each column header.
- Set indent, root node, array tag, and simplify options as needed.
- After converting, copy or download from each panel's actions.
Option details
- Add XML declaration: prepends <?xml version="1.0" encoding="UTF-8"?> to XML output.
- Use item tag for arrays: keeps array output in XML consistent and easier to parse.
- Simplify JSON output: for XML → JSON, plain text nodes can be reduced to string values.
Tips
- If parsing fails, use Format first to inspect whether the input structure is valid.
- XML attributes are preserved under attr fields to keep round-trip fidelity.
