How this service works

Convert XML to JSON (attributes prefixed with @, text as #text, repeated tags become arrays) or JSON back to XML. Give from/to and the source string.

Output

Returns the converted string in the target format. XML→JSON output uses @ prefix for XML attributes, #text for text node content, and collapses repeated sibling tags into arrays. JSON→XML output reconstructs the XML document from the JSON structure.

Example use cases

Parse SOAP API XML response

“I got this XML back from a SOAP endpoint and need it as JSON so my app can process it — convert it from XML to JSON: '<response><status code="200">OK</status><items><item>foo</item><item>bar</item></items></response>'”

Feed legacy system with XML

“My legacy system only accepts XML — take this JSON object '{"order":{"id":"42","product":"widget","qty":3}}' and convert it to XML for me.”

Normalize RSS feed data

“I have an RSS feed payload in XML and I want to work with it as JSON — can you convert this XML to JSON: '<rss><channel><title>My Blog</title><item><title>Post 1</title></item><item><title>Post 2</title></item></channel></rss>'?”

When to prefer

Choose this endpoint when you need a simple, reliable XML↔JSON round-trip conversion with consistent conventions (@ for attributes, #text for text nodes, arrays for repeated tags). Ideal for agents processing legacy XML APIs, RSS/Atom feeds, SOAP responses, or configuration files that need to be converted for downstream JSON-first systems — or vice versa.

Side effects

Malformed XML input causes parse error with descriptive message
Invalid JSON input returns parse error
Missing 'from' or 'to' direction parameter returns validation error
Deeply nested or extremely large documents may hit size/depth limits
Unsupported encoding or non-UTF-8 characters may cause transformation errors
