What is XML to JSON Converter?
XML to JSON & JSON to XML Converter is a bi-directional data transformation tool designed to convert XML structures into JSON objects and vice-versa. Modern web applications and microservices rely primarily on JSON APIs, whereas legacy systems, enterprise SOAP services, Android applications, and financial portals often communicate via XML. Converting data structures manually between these formats can lead to missing properties, array serialization bugs, and broken data pipelines. Our converter parses the source format into an internal object model and serializes it cleanly into the target format according to standard mapping specifications.
How to use XML to JSON Converter
Select your desired conversion direction: 'XML to JSON' or 'JSON to XML'. Paste your raw payload into the input panel. The tool automatically parses the syntax and produces the transformed data structure in real time. Configure structural settings, such as preserving XML attributes as '@' prefixed keys in JSON, or customizing the root element tag name when converting JSON to XML. Copy the converted string or download it directly as a file.
Key features
- Bi-directional instant conversion: XML to JSON and JSON to XML
- Configurable XML attribute mapping (@attribute keys vs property attributes)
- Automatic array detection for repeated XML element tags
- Configurable root tag naming for JSON to XML output
- Syntax color-highlighted dual editor layout
- Instant copy to clipboard and file download export
- 100% private client-side processing
Common use cases
- Migrating legacy SOAP XML backend services to modern JSON REST API endpoints
- Transforming JSON API payloads into XML for enterprise system consumption
- Parsing XML RSS/Atom feed items into JSON objects for web frontend components
- Converting Android manifest XML configurations to JSON for automated scripting
- Preparing multi-format test fixtures for automated API integration suites
Technical details & standards
The conversion engine leverages a fast DOM parser and JSON tree generator. When converting XML to JSON, element attributes, child nodes, CDATA blocks, and repeated tag lists are mapped into JSON arrays and objects. When converting JSON to XML, primitives (strings, numbers, booleans) and nested arrays are wrapped in valid XML tags. All processing operates 100% client-side within your browser sandbox, guaranteeing that enterprise database dumps, API payloads, and configuration files remain completely private.
Frequently asked questions
How are XML attributes represented when converting XML to JSON?
XML attributes can be configured to map as '@' prefixed properties (e.g., '@id': '123') or merged as direct key-value pairs inside the JSON object.
What happens to repeated XML tags during XML to JSON conversion?
Multiple sibling XML tags with the same name (e.g., <item>A</item><item>B</item>) are automatically converted into a clean JSON array (['A', 'B']).
Is my data safe?
All processing happens entirely in your browser. Your data never leaves your device and is never sent to or stored on a server.
Does it work offline?
Yes. Once the page has loaded, most tools keep working without an internet connection.
