XML ↔ JSON Converter
Convert between XML and JSON formats instantly. Bidirectional conversion with attribute support.
XML JSON Converter - Convert XML to JSON & JSON to XML Online
Convert between XML and JSON formats with our free online converter. Supports both directions - paste XML to get JSON or paste JSON to get XML.
Select your conversion direction—XML to JSON or JSON to XML—then paste your data into the input area. For XML inputs, the tool parses element names as object keys, text content as values, and preserves attributes as special properties. When converting JSON to XML, object keys become element names and arrays generate repeated sibling elements. The converter handles nested structures automatically, maintaining hierarchy in both formats. Processing runs entirely in your browser using native parsing APIs, ensuring your configuration files or API responses remain private.
API developers encounter XML responses from legacy SOAP services that need conversion to JSON for modern REST clients. Frontend engineers working with SVG files convert them to JSON for manipulation before rendering. DevOps teams transform XML configuration files from older systems into JSON for container orchestration tools. Data analysts receive XML exports from enterprise systems and convert them to JSON for easier processing with JavaScript-based analytics tools.
XML attributes often become special keys in JSON (like @attribute or $attribute)—know your converter's convention before integrating the output. Namespaces in XML can cause unexpected nesting in JSON; strip them beforehand if they're not semantically important. When converting JSON arrays to XML, ensure your target system can handle repeated sibling elements rather than expecting a wrapper element. Self-closing XML tags should produce empty strings in JSON, not null values. Test round-trip conversion with sample data to verify structural fidelity.
All processing happens directly in your browser. Your files never leave your device — no server uploads, no cloud storage, no data retention. The tool works offline once loaded, requires no registration, and is completely free with no usage limits.
Frequently Asked Questions
How are XML attributes handled?
XML attributes are converted to JSON properties prefixed with @ symbol. For example, <item id="1"> becomes {"@id": "1"}.
Can I convert nested XML?
Yes, deeply nested XML structures are fully supported and converted to equivalent nested JSON objects.
What happens with repeated elements?
Repeated XML elements with the same tag name are automatically converted to JSON arrays.
Is my data secure?
Yes, all conversion happens entirely in your browser. No data is sent to any server.
