JSON to XML
Instant JSON to XML conversion, 100% free.
The JSON to XML Converter converts JSON data into XML format instantly, entirely in your browser. Paste your JSON and get properly structured XML output ready to use.
Different tools and systems expect data in different formats. This converter removes the manual work of restructuring data by hand, reducing errors in the process.
How to Convert JSON to XML
- Paste your JSON data into the input box
- Click Convert
- Copy or download the XML result
Best Practices
- Validate your source data structure before converting for the cleanest output
- Check for nested structures that may need special handling depending on the target format
- Keep sensitive data out of anything pasted into an online tool
This tool is free to use with no signup required.
Frequently Asked Questions
How does JSON convert to XML structurally?
JSON objects typically become XML elements, JSON keys become element or attribute names, and JSON arrays become repeated sibling elements — the exact mapping conventions can vary slightly between converters.
Is my JSON data sent to a server?
No — processing happens entirely in your browser, and your JSON data is never uploaded or stored.
Does this handle nested or complex JSON structures?
Yes, the converter handles common nested objects and arrays, translating them into correspondingly nested XML elements.
Why would I need to convert JSON to XML?
Common reasons include integrating with legacy systems or APIs that require XML, generating XML feeds (like RSS), or working with tools and platforms that only accept XML input.
Does the conversion preserve all my original data?
Yes, for standard JSON structures — all keys and values are represented in the resulting XML, though the visual structure differs since XML and JSON have different formatting conventions.
Can I convert the XML back to JSON afterward?
Yes — an XML to JSON converter can typically reverse the process, though exact round-trip fidelity depends on how the original conversion structured attributes versus elements.
Does this add a root XML element automatically?
Yes, since valid XML requires a single root element, the converter typically wraps your JSON data in a root tag (often something generic like <root> or based on your data).
Is this useful for SOAP API integration?
Yes — SOAP-based web services require XML, so converting JSON data into XML format is a practical step when integrating modern JSON-based systems with older SOAP APIs.
Does JSON to XML conversion handle arrays correctly?
Yes, JSON arrays are typically converted into multiple repeated XML elements with the same tag name, representing each array item as a separate element.
Is there a size limit for conversion?
You can convert as much data as you need — this tool runs entirely in your browser with no signup or artificial limits.
The JSON to XML converter transforms JSON objects and arrays into well-formed XML markup, mapping JSON keys to XML element names.
Why JSON to XML Conversion Isn't Always Straightforward
JSON and XML model data differently, which means the conversion involves design decisions rather than a purely mechanical mapping. JSON has no native concept of XML attributes — every JSON key becomes a child element by default, since there's no equivalent syntax in JSON to distinguish "this should be an attribute" from "this should be a nested element." JSON also allows keys that aren't valid XML element names (starting with a number, containing spaces or special characters), which typically requires sanitizing or prefixing during conversion.
Handling Arrays: The Trickiest Part
- Repeated elements — a JSON array is usually converted into multiple sibling XML elements with the same tag name, since XML doesn't have a native array type the way JSON does.
- Root element requirement — XML documents must have exactly one root element, but a JSON array or object structure doesn't inherently define one, so converters typically wrap the output in a generic root tag unless a specific root name is specified.
- Empty arrays and JSON's empty value — these have no direct XML equivalent, so converters generally represent them as self-closing or empty elements.
Common Use Cases
This conversion direction is common when integrating with legacy enterprise systems, SOAP-based APIs, or older ERP/CRM platforms that still expect XML payloads while your application's internal data model is JSON-based. It's also useful for generating RSS/Atom-adjacent feeds or configuration files in ecosystems where XML remains the expected format.
