A Complete Guide to using XML to JSON Converter
Transform XML documents into clean JSON objects, preserving attributes and nested elements.
What exactly is the XML to JSON Converter?
The XML to JSON Converter is a free, browser-native tool that parses any XML document and transforms it into a clean, well-structured JSON object. It handles all XML features including nested elements, repeated sibling elements (which become JSON arrays), element attributes (captured under a '@attributes' key), text nodes, and mixed-content elements.
XML-to-JSON transformation is a common requirement when integrating with SOAP APIs, RSS feeds, configuration files, or any legacy system that uses XML as its data format. The resulting JSON is lightweight, directly consumable by JavaScript, Python, and most modern languages and frameworks.
The converter uses the browser's built-in DOMParser API — no external libraries, no npm packages, and no network requests. Your XML data never leaves your device.
How to Use This Tool
Transforming XML to JSON takes just a moment:
- Paste your XML document into the left input panel, or click 'Load sample' to see a full example.
- Choose your preferred JSON indentation (2 or 4 spaces) using the indent buttons.
- The JSON output is generated automatically in the right panel.
- If the XML is malformed, a descriptive parse error is shown in the output area.
- Click Copy above the output to copy the complete JSON to your clipboard.
Attributes are stored under '@attributes' keys in the output JSON. Repeated sibling XML elements are automatically grouped into a JSON array. Primitive-looking text values (numbers, booleans, empty strings) are coerced to their proper JSON types.
Common Developer Use Cases
XML to JSON conversion is a core step in modernizing data pipelines:
- SOAP API Integration: Convert SOAP API XML responses into JSON for easy consumption by modern JavaScript, Python, or Go applications.
- RSS & Atom Feeds: Parse RSS feed XML into JSON to display news headlines, blog posts, or podcast listings in a web application.
- Config File Migration: Transform legacy XML configuration files (Maven pom.xml, Spring XML, Android Manifest) into JSON for modern toolchains.
- Data Migration: Convert large XML data exports from legacy enterprise systems (ERP, CRM) into JSON for import into modern cloud databases.
- SVG Processing: Parse SVG XML to a JSON representation for programmatic manipulation of paths, shapes, and attributes in JavaScript.
Key Features
- Nested Element Support: Recursively converts unlimited levels of nested XML elements into proper JSON object hierarchy.
- Attribute Capture: XML element attributes are captured under '@attributes' keys rather than being silently discarded.
- Array Grouping: Repeated sibling elements with the same tag name are automatically combined into JSON arrays.
- Type Coercion: Numbers, booleans, and empty text nodes are converted to proper JSON types for clean, usable output.
