Conversor JSON ↔ XML

JSON ↔ XML Converter

JSON and XML have different structures, so conversion has a few choices. This tool converts both ways in real time, with two tweakable rules.

Two options

• Attribute prefix (default @_) — prefix used in JSON keys for XML attributes. Example: <book id="1"> → {"@_id": "1"}
• Text key (default #text) — JSON key holding the text content of an element when it also has attributes. Example: <title lang="en">Gatsby</title> → {"title": {"@_lang": "en", "#text": "Gatsby"}}

How to use

• Type in either side — the other converts automatically
• Sample button loads example data
• Swap button exchanges left and right
• Copy or download each format separately

Conversion rules

• Arrays — multiple child elements with the same name become a JSON array
• Attributes vs child elements — distinguished by the prefix
• Empty elements — <br /> → {"br": ""}
• Comments — stripped during conversion (not lossless)

Client-side only

Your data never leaves the browser. Safe for SOAP responses, API keys, internal configs.
