JSON to XML Converter
Convert a JSON object into clean, indented XML — or parse XML back into JSON with attributes and repeated tags handled automatically. Runs entirely in your browser.
About this tool
The JSON to XML Converter turns a JSON object into clean, indented XML — and parses XML back into JSON when you need the round trip. It is built for developers moving data between APIs and older systems: SOAP services, enterprise integrations and config formats that still speak XML.
Conversion happens entirely in your browser, so payloads with customer data, tokens or internal identifiers stay on your machine. Attributes, nested objects and repeated tags are handled automatically so the output stays faithful to the source structure.
How to use
- Choose the direction: JSON to XML, or XML to JSON.
- Paste your JSON object or XML document into the input area.
- The converter validates the input and reports the exact position of any syntax error.
- Read the formatted, indented result in the output panel.
- Copy the output to clipboard, or tweak the source and convert again.
Features
- Two-way conversion: JSON to XML and XML back to JSON.
- Pretty-printed, indented output that is easy to read and diff.
- Automatic handling of XML attributes when parsing back to JSON.
- Repeated tags collapse into JSON arrays so lists survive the round trip.
- Clear error messages that point to where invalid syntax was found.
- Runs fully client-side — payloads never touch a server.
Frequently asked questions
Does my JSON or XML get uploaded during conversion?
No. The conversion runs entirely in your browser with JavaScript, so sensitive payloads and configuration data never leave your device.
How are repeated XML elements represented in JSON?
When the same tag appears more than once under a parent, it is turned into a JSON array so the order and count of the elements are preserved.
What happens to XML attributes?
Attributes are kept when parsing XML into JSON, typically stored under a dedicated key so you can distinguish them from child elements.
Why does converting JSON to XML and back not give me an identical file?
JSON and XML have different data models — XML has attributes and ordering rules JSON lacks, and JSON has typed values XML treats as text. The data is preserved, but formatting and type hints may shift on a round trip.
Can it handle deeply nested structures?
Yes. Nested objects and arrays are converted recursively, so complex API responses and configuration trees are supported at any depth.
