Free JSON to XML Converter
Convert between JSON and XML both ways.
What is the JSON to XML Converter?
JSON and XML are the two formats data keeps arriving in — a modern API speaks JSON, a legacy system or a SOAP endpoint speaks XML, and sooner or later you need to move between them. Doing it by hand is tedious and error-prone once the nesting gets deep.
This converter translates JSON to XML and XML to JSON in your browser, so you can move data between formats without pasting it into an unknown server.

What does this tool do?
You pick a direction, paste your data, and the tool converts JSON to XML or XML to JSON.
Converting JSON to XML wraps values in element tags and repeats tags for arrays; converting XML to JSON turns attributes into @-prefixed keys and repeated tags into arrays.
Key features
Both directions
JSON → XML and XML → JSON.
Handles nesting
Works through deeply nested structures.
Arrays & attributes
Repeated tags and @-keys are mapped.
Validation
Flags invalid JSON or XML clearly.
Private
Runs in your browser — nothing uploaded.
Example
Common use cases
- Developers — Bridge JSON and XML APIs.
- Integrators — Feed legacy XML systems from JSON.
- QA engineers — Convert fixtures between formats.
- Data analysts — Reshape exported data.
- Students — See how the two formats map.
- API consumers — Read an XML response as JSON.
- Config editors — Move settings between formats.
- Anyone with mixed data — Convert quickly and privately.
Benefits
- It converts both ways without a round trip to a server.
- It handles nested objects and arrays.
- It maps attributes and repeated tags sensibly.
- It tells you exactly what's malformed if input is invalid.
Tips
- Validate or format your JSON first if conversion fails.
- XML needs a single root element — the tool adds <root> for JSON input.
- Attributes become @-prefixed keys when converting XML to JSON.
- Repeated XML tags become a JSON array of that key.
- XML has no real number or boolean types — everything comes back as text.
- Escape special characters are handled for you in XML output.
- For huge payloads, convert in smaller chunks.
- Keep a copy of the original before converting.
Common mistakes to avoid
Invalid JSON input
Fix: Fix syntax (quotes, commas) — validate with a JSON formatter first.
XML without a single root
Fix: Wrap XML in one root element; the converter requires valid XML.
Expecting typed values from XML
Fix: XML values convert to strings — cast numbers/booleans yourself afterward.
Losing attributes
Fix: They're preserved as @-prefixed keys; don't strip them if you need them.
How it works

Frequently asked questions
Both — JSON to XML and XML to JSON. Switch direction with a toggle.
When converting XML to JSON, attributes become @-prefixed keys and repeated child tags become arrays.
Both — JSON to XML and XML to JSON, switchable with a toggle.
When converting XML to JSON, attributes become @-prefixed keys (like @id) on the object.
JSON arrays become repeated XML tags; repeated XML tags become a JSON array of that key.
XML has no type system, so all values convert to strings. Cast them in your code if needed.
XML requires one root element, so the tool wraps the output in a <root> element.
No. Conversion happens entirely in your browser.
Conclusion
A JSON–XML converter moves data between the two formats instantly and privately, so mismatched systems can talk. Pair it with the JSON formatter and XML formatter to clean up either side.
