XML to JSON Converter
Convert XML documents, SOAP envelopes, and RSS/Atom feeds into structured JSON objects and arrays with configurable attribute syntax and namespace stripping.
Selecting a file allows the browser to read it locally. Files are processed locally in your browser when using supported tools. No upload required for supported workflows.
Drag & drop files to begin
Select or drag multiple files from your device. Entirely processed locally in your browser memory.
Client-Side XML to JSON Converter & Schema Parser
The XML to JSON Converter offers a fast, local-first utility for converting raw XML documents, RSS feeds, SOAP payloads, and XML configurations into clean JSON data structures. Designed with customizable attribute parsing, element array coercion, and configurable indentation, the tool streamlines API integrations and data migrations without exposing sensitive data to cloud services.
XML remain widely used in enterprise software, web services, and legacy configurations, while JSON is the standard format for modern web APIs and JavaScript applications. Transforming XML to JSON manually or via remote converters can expose confidential payload attributes and waste developer time.
Our converter parses XML DOM nodes in memory, converting tags into JSON keys, nested elements into nested objects or arrays, and XML attributes into configurable JSON property prefixes (@ or _), returning instantly formatted JSON.
Core Tool Capabilities
- Bidirectional Structure Parsing: Converts complex nested XML trees, CDATA blocks, and tag attributes into structured JSON objects.
- Custom Attribute Prefixing: Configure how XML attributes are represented in JSON (e.g. @attribute, _attribute, or merged fields).
- Array Coercion Rules: Automatically convert repeated XML sibling tags into clean JSON arrays.
- Pruned Whitespace & Comments: Optionally strip empty text nodes, line breaks, and XML comments for minimal JSON payload sizes.
- Real-Time Validation & Formatting: Highlights syntax errors in XML and formats output JSON with 2-space or 4-space indentation.
- 100% Local Browser Security: Processes all XML files and strings locally inside browser memory with zero cloud transmission.
Local Browser Privacy

Frequently Asked Questions
- How are XML attributes converted to JSON?
- XML attributes are stored as key-value pairs inside the object corresponding to the tag. By default, attribute keys are prefixed with '@' (e.g. '@id': '123') to distinguish them from child element tags.
- Is my XML uploaded to any server?
- No. The conversion is performed using your browser's native DOMParser engine entirely on your client device.
