¿Qué es JSON to XML?
A JSON to XML converter translates between two of the most common structured data formats on the web: JSON, which represents data as nested objects, arrays, and primitive values, and XML, which represents the same information as nested tags and attributes. This matters because plenty of systems — SOAP APIs, legacy enterprise integrations, RSS/Atom feeds, configuration formats used by older tooling — still speak XML exclusively, while most modern APIs and JavaScript codebases speak JSON. Converting between them isn't a purely mechanical exercise: JSON allows a document with several top-level keys or a bare array, while XML requires exactly one root element, so a converter has to make a sensible choice about how to wrap or group data so the result is both valid XML and easy to read. This tool handles that automatically in both directions.
Cómo usar JSON to XML
- Pick a direction using the JSON ⇄ XML toggle at the top (or click the swap button to reverse it, carrying today's output into the other side as new input).
- Paste or type your source document into the left panel.
- The converted result appears instantly on the right, syntax-highlighted for its format.
- Click "Load sample" to see a worked example, or copy the result once you're happy with it.
Ejemplos
Object with a single root-shaped key
Entrada
{"user": {"name": "Ada", "id": 1}}
Salida
<user> <name>Ada</name> <id>1</id> </user>
Multi-key object (wrapped in a synthetic root)
Entrada
{"name": "Ada", "active": true}
Salida
<root> <name>Ada</name> <active>true</active> </root>
Errores comunes
- Expecting XML output with no wrapping root tag when the source JSON has multiple top-level keys or is a bare array — XML's single-root rule makes some wrapping unavoidable.
- Assuming attribute output is supported symmetrically in both directions — XML → JSON preserves attributes, but JSON → XML does not currently produce them.
- Forgetting that empty XML tags (<a></a>) become an empty string in JSON, not null — XML has no native null representation.
Por qué usar esta herramienta
- Runs entirely client-side — no document you convert is ever sent to a server.
- Automatically picks a sensible root element instead of forcing you to manually restructure JSON before conversion.
- Reversible in one tool — swap direction and immediately feed today's output back in as the next input.
