XML ⇄ JSON
Convert between XML and JSON
100% free. Runs entirely in your browser - your files and data never leave your device and nothing is uploaded to any server.
About this tool
XML and JSON are both structured data formats used across different systems - XML is common in older enterprise systems, RSS feeds, and config files, while JSON is the standard for modern web APIs. This tool converts between the two, useful when you need to feed XML data into a JSON-only system or vice versa.
How to use this tool
- Choose conversion directionSelect XML-to-JSON or JSON-to-XML based on integration requirement.
- Paste source payloadInput well-formed structured data from your source system.
- Convert and inspect structureReview arrays, attributes, and nested nodes after mapping.
- Copy validated outputUse converted payload in API, ETL, or middleware workflow.
Converting an RSS feed to JSON
Paste the feed’s XML and convert it: each <item> becomes an object in an array with its title, link, description and publication date as fields, ready for a script or a no-code tool.
Repeated tags become arrays, but a tag that appears only once can come out as a single object, so code that reads the result should handle both.
Key features
- Bridges legacy XML systems and modern JSON APIs quickly.
- Reduces manual transformation errors in integration work.
- Speeds debugging of payload format incompatibilities.
- Useful for developers, analysts, and data engineers.
Common uses
- Transforming XML feeds for JSON-only services.
- Converting API responses for legacy enterprise consumers.
- Testing middleware mapping rules during system migration.
- Preparing sample payloads for technical documentation.
Tips for better results
- Validate source syntax before conversion to avoid cascading errors.
- Review attribute mapping conventions after XML-to-JSON conversion.
- Check array handling for repeated sibling elements.
- Run round-trip tests for critical schemas before production use.
Mistakes to avoid
- Expecting perfect one-to-one round-trip for complex schemas.
- Ignoring namespace nuances in heavily structured XML.
- Treating all values as strings without post-conversion typing.
- Deploying transformed payloads without downstream schema validation.
Frequently asked questions
XML attributes are typically represented as special keys in the resulting JSON (since JSON has no native concept of "attributes" vs "content"), so the structure will look slightly different even though the data is preserved.
For straightforward data, yes. XML's attribute/element distinction doesn't map perfectly one-to-one with JSON's simpler key-value structure, so a round trip through both formats can shift some structural details.
Basic namespace prefixes are generally carried through as part of element names, though highly complex namespace setups may need manual review after conversion.
Paste the feed's XML here: each <item> becomes an entry with its title, link, description and date. That makes a feed easy to use in JavaScript or to import into a tool that only reads JSON.
Common causes are an unescaped & (write &), a tag that is opened but never closed, mismatched capitalisation between opening and closing tags, or more than one root element.
Elements that contain both text and child tags, like <p>Hello <b>world</b></p>, do not map neatly to JSON. Converters usually put the text in a special key such as #text, so check those fields after converting.
