How to Convert XML to JSON Online for Free

Plenty of legacy systems and APIs still return data as XML, but most modern code, especially JavaScript and web APIs, is built around JSON. Converting XML to JSON makes that data far easier to parse, manipulate, and pass around in current tooling.

When you need XML to JSON conversion

• Integrating a legacy XML API response into a modern JavaScript or web application
• Making an XML config or data file easier to work with in code that expects JSON
• Simplifying a deeply nested XML document into a more code-friendly structure
• Preparing XML data to be consumed by a tool or library that only accepts JSON

How to convert XML to JSON, step by step

1. Open the XML to JSON tool.
2. Paste or upload your XML content.
3. The tool converts the tags, attributes, and content into JSON structure.
4. Preview the result to confirm the mapping looks correct.
5. Copy or download the JSON output.

Tips for a clean conversion

• Validate the XML first. If the source XML isn't well-formed, run it through the XML Formatter first to catch and fix errors.
• Review how attributes are represented. XML attributes don't have a single universal JSON equivalent — check the output convention matches what your code expects.
• Watch for repeated tags. Repeated sibling tags in XML typically become an array in JSON — confirm that's reflected correctly in the result.

Common questions

Do XML attributes convert cleanly to JSON? Yes, though the exact representation (as a nested key or a prefixed field) depends on the conversion convention used — check the preview against what your code expects.

Will nested XML elements be preserved? Yes — nested structure carries over into nested JSON objects and arrays.

Can I convert the JSON back to XML later? Most JSON-to-XML libraries can reverse the process if you need to send the data back to an XML-based system later.
