Xml To Json Converter — Free Online Tool

An XML to JSON converter parses XML documents into structured JSON data. Developers use it to consume SOAP API responses in modern JavaScript applications, migrate legacy XML configs, or extract data from XML feeds for JSON-based processing pipelines.

Features

• Attribute preservation: XML attributes are preserved with an @_ prefix so they are not confused with child elements.
• Text node handling: Mixed content elements use #text for text nodes alongside child elements.
• Boolean and numeric parsing: Recognizes boolean and numeric values in XML and converts them to native JSON types.
• Pipeline chaining with other tools: Chain output directly into other Prism tools for multi-step workflows.
