About This Tool
Free, private, in-browser XML to JSON converter. Automatically detect numbers, booleans, and arrays with configurable attribute mapping, zero latency and 100% privacy.
How to Use
- Paste XML Document: Insert raw XML data, SOAP envelopes, or RSS feeds into the input workspace.
- Configure Parsing Options: Toggle Include Attributes, Trim Whitespace, and Auto-Detect Types according to your schema needs.
- Execute Conversion: Click Convert to JSON to trigger instant client-side DOM parsing and type inference.
- Copy or Export JSON: Review the structured output and copy the formatted JSON directly to your clipboard.
Frequently Asked Questions
How does the converter handle XML attributes?
By default, XML attributes are preserved by assigning them keys prefixed with an '@' symbol (for example, <user role='admin'> maps to {'@role': 'admin'}). If you disable the 'Include Attributes' option, all attribute metadata is stripped, resulting in a cleaner, minimalist JSON structure containing only element text values.
Does the tool automatically convert numbers and booleans?
Yes. When the 'Auto-Detect Types' option is enabled, strings representing numbers (e.g., '1024', '99.95') and booleans ('true', 'false') are automatically coerced into their native JSON numeric and boolean data types rather than remaining as strings. Empty elements are mapped to JSON null.
How are multiple XML elements with the same tag name converted?
When a parent element contains two or more sibling elements sharing the exact same tag name, the converter automatically groups their values into a JSON array ([]), preserving the order in which they appeared in the source XML document.
What happens to CDATA sections during conversion?
CDATA blocks (<![CDATA[ ... ]]>) contain raw unescaped characters. The converter extracts the inner content verbatim as a plain text string, ensuring that embedded HTML tags, mathematical symbols, or scripts are preserved without corruption.
Can I convert large XML files exceeding several megabytes?
Yes. Because all parsing and conversion operations execute locally within your browser's high-performance JavaScript engine, the tool can process multi-megabyte payloads in milliseconds without encountering server timeout limits or payload size caps.
Is my proprietary or customer XML data kept private?
Yes, absolutely. The tool operates under a 100% client-side execution guarantee. No XML data, JSON output, or user telemetry is ever transmitted over the network or saved to remote servers. Everything runs entirely within your device's browser memory.
Why does XML need to be converted to JSON?
Modern web applications, mobile apps, and microservice architectures overwhelmingly use JSON as their standard data exchange format due to its lightweight syntax, fast native parsing in JavaScript, and direct compatibility with NoSQL document stores like MongoDB. Converting legacy XML into JSON allows modern applications to consume enterprise data seamlessly.
How does the converter handle XML namespaces?
XML namespace prefixes (such as <soap:Envelope> or <xmlns:item>) are preserved directly within the JSON property keys (e.g., 'soap:Envelope'), ensuring that fully qualified names and schema distinctions remain intact for downstream processing.
