JSON to XML Converter

What is JSON to XML conversion?

XML is still the backbone of many enterprise systems, SOAP APIs, RSS feeds, and configuration formats, even though JSON has become the default for modern web APIs. Converting JSON to XML takes your object or array structure and rebuilds it as nested XML elements, so data produced by a modern app can be handed off to an older or more XML-centric system without you writing the transformation by hand.

This kind of bridging comes up more often than you'd expect, especially at larger organizations where new services are built JSON-first but still need to talk to established systems, banking infrastructure, government platforms, and enterprise software, that were built around XML long before JSON existed.

How to convert JSON to XML online

Paste your JSON or upload a .json file, then click Convert to XML. Each key in your JSON becomes an XML tag, and each value becomes that tag's content. Arrays are handled by repeating the same element once for every item, and nested objects become nested elements, so the resulting XML mirrors the structure of your original JSON as closely as XML allows.

The output is properly indented and formatted, so it is easy to review by eye before handing it off, rather than a single dense line of tags that's hard to visually verify.

Common use cases

• Sending data to a legacy SOAP API or enterprise system that only accepts XML.
• Generating configuration files for tools and platforms that use an XML-based format.
• Producing an RSS or Atom-style feed structure from JSON data.
• Bridging a modern JSON-based service with an older system during a migration.
• Creating sample XML payloads for documentation or testing an XML-consuming endpoint.

Tips for best results

JSON keys that aren't valid XML tag names, like ones starting with a number or containing spaces, may need to be renamed in your source JSON first for the cleanest output. If your target system expects specific XML attributes rather than nested elements, you may need to adjust the generated XML slightly to match that system's exact schema.

The transformation happens entirely in your browser, so JSON payloads containing API keys, customer data, or internal configuration never leave your device. It is free with no sign-up, produces clean, properly indented XML, and works instantly regardless of how deeply nested your JSON structure is.

Because XML has stricter rules than JSON about what counts as valid content inside a tag, it's good practice to skim the generated output for anything unusual, like text containing characters that need escaping, before sending it on to a strict XML-consuming system that might reject malformed markup.

It's also worth deciding upfront whether you need a specific root element wrapping the whole document, since different systems expect different top-level tag names. If your JSON is an array at the top level rather than a single object, consider wrapping it in a named object first, so the generated XML has a sensible single root element rather than multiple top-level siblings, which isn't valid XML on its own.
