Frequently Asked Questions
How are JSON arrays converted to XML?
Each item in a JSON array is converted into an XML element that repeats the same tag name. For example, items in an items array are listed as consecutive <item> tags.
How are XML attributes and elements converted to JSON?
XML attributes are converted to keys prefixed with @ by default, and text nodes are converted to a configurable special key (e.g., #text). You can adjust the conversion rules via options to produce the shape you need.
Can this be used when integrating a REST API and a SOAP API?
Yes, REST APIs typically use JSON while SOAP APIs use XML. When you need to convert data between the two systems, you can use this tool to quickly check and transform the format.
Is bidirectional conversion supported?
Yes, both JSON to XML and XML to JSON are supported. Enter your source data in the left panel and the conversion result appears immediately in the right panel.
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.
