Bidirectional JSON and XML Conversion Tool
Convert between JSON and XML formats with flexible options:
Convert between XML-based SOAP services and JSON-based REST APIs. Transform SOAP responses to JSON for modern web applications, or convert JSON data to XML for legacy SOAP integrations.
Migrate application configurations between XML and JSON formats. Convert legacy XML config files to modern JSON format, or transform JSON configs to XML for systems that require it.
Exchange data between systems that use different formats. Convert XML from enterprise systems to JSON for web applications, or transform JSON data to XML for business process automation tools.
Transform structured documents between formats. Convert XML documents like RSS feeds, sitemaps, or SVG files to JSON for easier processing in JavaScript applications.
Bridge modern JSON-based applications with legacy XML systems. Convert data formats seamlessly for enterprise integration platforms, middleware, and data migration projects.
Develop and test web services that support both XML and JSON. Quickly convert test data between formats, validate API responses, and ensure compatibility across different client requirements.
JSON and XML are two fundamental data interchange formats, each with unique strengths for different applications.
JSON (JavaScript Object Notation) is a lightweight, text-based data format that uses human-readable text to store and transmit data objects. It supports hierarchical structures with nested objects and arrays, using simple syntax with curly braces {} for objects and square brackets [] for arrays. JSON is the preferred format for modern web APIs, configuration files, and data storage due to its simplicity and native JavaScript compatibility. It's compact, easy to parse, and widely supported across all programming languages.
XML (eXtensible Markup Language) is a flexible, self-descriptive markup language designed for storing and transporting data. XML uses tag-based syntax with opening and closing tags (like <element>content</element>), supporting complex features including attributes (<element attr="value">), CDATA sections for unparsed content, namespaces for avoiding naming conflicts, and XML schemas for validation. XML excels at representing document-oriented data and is widely used in enterprise systems, SOAP web services, configuration files, and data exchange where schema validation and human readability are important. While more verbose than JSON, XML's extensibility and metadata capabilities make it ideal for complex data structures.
Select 'XML to JSON' mode, paste your XML data into the input area, configure how you want attributes handled (@ prefix or separate object), then click Convert. The tool will automatically transform your XML structure into JSON format, preserving the hierarchy and data.
When converting JSON to XML, you can specify a custom root element name in the 'XML Root Element' field. If left empty, it defaults to 'root'. The root element wraps all your JSON data, as XML requires a single root element.
You have two options: (1) @ Prefix notation - attributes become JSON properties prefixed with @ (e.g., <element id="1"> becomes {"@id": "1"}), or (2) Separate Object - attributes are grouped in a special _attributes object. Choose the option that best fits your application's needs.
Yes, the converter fully supports nested XML elements and converts them to nested JSON objects. Deep hierarchies are preserved in both directions, maintaining the complete structure of your data.
CDATA sections (used for unparsed text content in XML) are converted to regular JSON string values. When converting back from JSON to XML, special characters are automatically escaped to ensure valid XML output without requiring CDATA sections.
Yes, XML namespaces are supported. Namespace prefixes are preserved in element names when converting to JSON (e.g., <ns:element> becomes a JSON property 'ns:element'). When converting back to XML, the namespace prefixes in JSON keys are preserved in the XML output.
The converter uses UTF-8 encoding for both JSON and XML, ensuring full support for international characters, special symbols, emoji, and non-Latin scripts. This provides maximum compatibility across different systems and languages.
Absolutely. All conversion happens entirely in your browser using JavaScript. Your data is never uploaded to any server or transmitted over the network. This ensures complete privacy and security for sensitive or confidential data.
