Conversion Details
XML → JSON
Converts XML elements to JSON objects, attributes to @ prefixed keys, and handles text nodes, nested elements, and arrays.
JSON → XML
Converts JSON objects to XML elements, @ prefixed keys to attributes, with proper escaping and XML declaration header.
All conversion happens locally in your browser. No data is sent to any server.
Technical Specification
XML-to-JSON Conversion Engine & Data Transformation
Overview
The ToolsForges XML-to-JSON converter transforms XML documents into clean, properly structured JSON objects, enabling developers to migrate data feeds, convert configuration formats, and bridge XML-based APIs with modern JSON-native applications. Paste your XML string and receive an instantaneous conversion that preserves element hierarchy, attribute mapping, and text content.
Feature Specifications
- Attribute PreservationConvert XML attributes to JSON properties using configurable naming conventions, ensuring that metadata stored in attributes is preserved in the converted output without data loss.
- Array Handling OptionsConfigure how repeated XML elements are converted — as JSON arrays or sequential properties — to match the conventions expected by your consuming application.
- Text Content ExtractionExtract text content from mixed-content XML nodes and map them to JSON properties, preserving the semantic meaning of elements that combine text and child elements.
- Pretty-Print OutputReceive the converted JSON with configurable indentation for immediate readability, or compact output for production use where file size is a priority.
Architecture
The converter uses React useState for XML input and the browser's DOMParser API for parsing. The conversion engine traverses the DOM tree, mapping element names, attributes, and text content to JSON properties following configurable conventions.
Frequently Asked Questions
How are XML namespaces handled in the JSON output?
Namespaced element names are preserved as-is in the JSON property names. You can configure whether namespace prefixes are included or stripped based on your conversion requirements.
Can I convert SVG files to JSON?
Yes. SVG is XML-based and the converter processes it like any other XML document. The resulting JSON represents the SVG element hierarchy as nested objects.
Does the converter handle CDATA sections?
Yes. CDATA sections are extracted as text content and mapped to the corresponding JSON property, preserving the original text without the CDATA wrapper.
Is my XML data stored?
No. All XML input and converted JSON output are processed entirely within your browser. No document data is transmitted to external servers.
