JSON → XML Translator

Convert a JSON API response into valid, properly nested XML — for the legacy systems, older enterprise APIs, or specific integrations that still require XML rather than JSON.

Plenty of modern tooling works exclusively in JSON, but a meaningful number of older enterprise systems, SOAP-based APIs, and specific industry integrations still expect XML, and hand-converting a nested JSON structure into correctly formed XML tags is tedious and easy to get subtly wrong, especially around how arrays should be represented (a detail JSON and XML handle very differently).

Paste your JSON, and it converts into valid XML with each object key becoming an element tag. Configure how arrays should be represented, since XML has no native array concept — options include repeating the same element tag for each array item (the most common convention) or wrapping items in a container element. Set a root element name, since XML requires exactly one top-level element while JSON can start with any structure.

Frequently asked questions

Why does XML need special handling for arrays when JSON doesn’t?

JSON has arrays as a first-class structure, but XML doesn’t — an array has to be represented as a convention (usually repeated sibling elements with the same tag name), which isn’t uniquely defined the way JSON’s array syntax is, so the conversion requires you to choose which XML convention to follow.

Does the conversion handle nested objects and arrays correctly, several levels deep?

Yes, nested structures convert recursively into correspondingly nested XML elements, preserving the full original structure regardless of depth.

Can this go the other direction too, XML back into JSON?

This tool is focused on JSON-to-XML specifically; converting XML back to JSON involves different structural ambiguities (like distinguishing attributes from child elements) that a dedicated XML-to-JSON tool would need to handle with its own specific configuration options.
