🔄 JSON ↔ XML Converter

What Is JSON to XML Conversion and Why Do Developers Need It?

JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are the two most widely used data interchange formats. While JSON dominates modern web APIs and JavaScript applications, XML remains critical in enterprise systems, SOAP APIs, Android layouts, RSS feeds, SVG graphics, and configuration files like Maven's pom.xml and .NET's Web.config.

Key Features of This Free JSON ↔ XML Converter

• Bidirectional conversion — Convert JSON to XML or XML to JSON with a single click
• Proper XML generation — Creates well-formed XML with correct nesting, indentation, and a root element
• Attribute handling — XML attributes are mapped to @attribute keys in JSON
• Array support — JSON arrays are converted to repeated XML elements; repeated XML siblings become JSON arrays
• Syntax validation — Instant error detection for both invalid JSON and malformed XML
• File upload support — Upload .json or .xml files for instant conversion

Common Use Cases

• API migration — Converting REST JSON APIs to SOAP XML format or vice versa
• Configuration files — Translating between JSON config (package.json) and XML config (pom.xml, Web.config)
• Data exchange — Converting between systems that use different formats
• RSS and Atom feeds — Parsing XML feeds into JSON for JavaScript applications
• Legacy system integration — Bridging modern JSON APIs with legacy XML-based enterprise systems
