XML to JSON Converter
Convert XML elements into clean JSON objects with tree schema visualization.
Options & JSON Result
What Does the XML to JSON Converter Do?
The XML to JSON Converter takes XML markup — with its elements, attributes, and nested hierarchy — and transforms it into equivalent JSON structure. This is one of the most common data format migrations developers face when integrating legacy systems, REST APIs, or configuration files that use XML with modern JavaScript applications that expect JSON.
The conversion runs entirely in your browser. Your XML data — which may contain sensitive database schemas, API definitions, SOAP payloads, or internal system configs — never leaves your device. Unlike online converters that transmit your content to external servers for processing, this tool provides the same output with zero data exposure risk.
The converter handles XML attributes (mapped to _attributes), text nodes (mapped to _value), and nested XML elements, producing clean JSON that preserves the document structure. Arrays are inferred automatically when multiple sibling elements share the same tag name.
Once loaded, the tool works fully offline — useful in enterprise environments with restricted internet access, or when working with confidential XML from internal systems.
How It Works
- 1 Paste Your XML: Drop well-formed XML markup into the input textarea, or drag an .xml file into the editor.
- 2 Click Convert: The converter parses the XML tree using the browser's native DOMParser and maps it to equivalent JSON structure.
- 3 Review the Output: The resulting JSON appears in the output panel with 2-space indentation, ready to inspect, copy, or download.
- 4 Download or Copy: Click Download JSON to save the converted file, or Copy to clipboard for immediate use in your code.
Key Features
Attribute Preservation
XML attributes are preserved in the JSON output as _attributes objects, so no data is lost during conversion.
Nested Structure Support
Deep XML hierarchies are faithfully mapped to nested JSON objects. Repeated elements are automatically converted to arrays.
100% Client-Side
Your XML never leaves your browser. Safe for converting SOAP payloads, internal API definitions, and confidential configs.
Download as JSON
Export the converted JSON directly as a .json file without copying and pasting manually into an editor.
Common Use Cases
Legacy API Migration
Convert XML responses from older SOAP or REST-XML APIs into JSON for use with modern JavaScript frontends and mobile apps.
Config Format Migration
Convert XML-based configuration files (Maven pom.xml, Spring configs, etc.) to JSON for tools that require JSON config format.
Data Processing Pipelines
Convert XML data exports from ERPs, CRMs, or database systems to JSON for further processing in JavaScript or Python pipelines.
XML vs JSON: Format Comparison
| Feature | XML | JSON |
|---|---|---|
| Verbosity | More verbose (open+close tags) | ✅ More compact |
| Attributes support | ✅ Native attribute support | ❌ No native attribute concept |
| Human readability | Readable but verbose | ✅ Cleaner and more concise |
| JavaScript support | Requires parsing library | ✅ Native JSON.parse() |
| API usage | Older SOAP/REST-XML APIs | ✅ Modern REST APIs |
| Schema validation | ✅ XSD schema support | JSON Schema (less mature) |
Best Practices for XML to JSON Conversion
- Validate XML Before Converting: Ensure the XML is well-formed before conversion. Invalid XML causes parser errors. Use a validator if needed.
- Review Attribute Mapping: XML attributes become _attributes objects in the JSON. Review these in the output and rename fields as needed for your API schema.
- Handle Arrays Carefully: When multiple XML elements share the same name, they're mapped to a JSON array. Verify that arrays are inferred correctly in your output.
- Check Namespace Handling: XML namespaces (e.g., xmlns:) may appear in the JSON output. Strip or transform these if your target system doesn't need them.
- Test with Real Data: Always test the conversion with actual data samples from your system, not minimal examples, to catch edge cases.
- Format After Converting: After conversion, use the JSON Formatter to inspect and validate the structure before integrating it into your codebase.
- Never Upload Confidential XML Online: SOAP payloads, API definitions, and internal configs may be sensitive. Always use this local tool — no data leaves your device.
Frequently Asked Questions
Absolutely. All conversion runs in your browser using the native DOMParser API. Your XML never leaves your device — no server, no uploads, no logging.
Yes. XML element attributes are mapped into a special _attributes object in the JSON output so no data is lost during conversion.
When multiple sibling elements share the same tag name, they are automatically collected into a JSON array in the output.
Yes. SOAP XML is valid XML and converts normally. SOAP namespaces will appear in the JSON output and can be cleaned up after conversion.
Yes. Performance depends on your browser's available memory. Files of a few MB convert instantly. Very large files (100MB+) may be slow depending on your system.
Yes. Once the page is loaded, you can disconnect and continue converting XML. All conversion logic runs in the browser.
DTD declarations, processing instructions, and XML comments are not mapped to JSON. Only element data, text nodes, and attributes are preserved.
