The XML to JSON Converter bridges legacy XML data with modern JSON workflows. All processing is 100% browser-based — your sensitive business logic, user data, and configurations remain completely private.
What is XML and Why Convert?
XML is highly structured but verbose. JSON is lightweight and maps directly to modern programming language data structures. Converting XML to JSON typically reduces file size by 30-50% while making data easier to parse and transmit.
How to Use
- 1Paste XML: Copy your XML data into the input text area.
- 2Click Convert: The tool parses XML and generates JSON instantly.
- 3Review output: See formatted JSON with file size comparison.
- 4Copy result: Use the Copy button for your code editor or project.
Conversion Rules
Tag name → key, text content → value.
Placed in
@attributes object to preserve metadata.Children become nested JSON objects preserving hierarchy.
Siblings with same tag name become JSON arrays.
The Conversion Logic
Uses the browser's native DOMParser to build an XML Document Object Model. A recursive function traverses every node — elements become JSON keys, nested elements become objects/arrays, and attributes go in @attributes. This structural approach ensures zero data loss.
Common Use Cases
Convert legacy SOAP XML responses to JSON for modern APIs.
Convert XML feeds to JSON for array-based manipulation.
Import old XML settings into modern NoSQL databases.
View raw XML API responses as clean, hierarchical JSON.
