🗂️ JSON to XML Converter
Convert JSON into XML in your browser. Name the root element, decide how arrays are wrapped, and switch pretty-printing, CDATA and the XML declaration on or off. Keys that start with @ become attributes, so output from an XML-to-JSON converter can be turned back into XML. Nothing leaves your device.
Paste JSON, get XML. Object keys become elements; keys prefixed with @ become attributes on the surrounding element; a #text key becomes the element's text. Arrays either repeat their key or nest inside it under an item name you pick. Characters XML forbids in element names are replaced with an underscore and the renamed elements are listed under the output. The practical limit is about 1 MB of input.
Array wrapping off repeats the key per item; on nests the items inside it.
What Is a JSON to XML Converter?
This tool converts JSON to XML — the format still required by SOAP services, RSS and sitemap feeds, Android and Java resource files, and plenty of enterprise config. Paste a JSON object or array and the tool walks it, turning keys into elements, @-prefixed keys into attributes, and #text into element text. That naming convention is the one most XML-to-JSON converters emit, so a document can survive the round trip. Everything runs client-side.
📋 When to Use
Use it when a system on the other end speaks XML and your data is JSON: posting to a SOAP endpoint, generating an RSS or sitemap fragment, filling an Android strings.xml, or preparing a payload for a legacy integration. It also helps when you have JSON that came from XML and need the original shape back.
⚙️ How It Works
The tool JSON.parse()s your input, then walks the value recursively. Objects become elements, @key pairs become attributes on the parent, #text becomes text content, and null becomes an empty element such as <note/>. Text is escaped for &, < and >; with CDATA on, values containing markup are wrapped in <![CDATA[…]]> instead, and a literal ]]> inside the value is split so the section stays valid.
Limitations
- Element names are sanitised, not rejected. Characters XML forbids become
_and a leading digit gets an_prefix; the tool lists every rename under the output. - No namespace handling. A key like
ns:tagkeeps its colon only if the rest of the name is valid; the tool does not declare prefixes for you. - No XML to JSON. This direction only — the reverse is a separate tool.
- ~1 MB practical limit. Larger input is rejected before parsing to keep the tab responsive.
Privacy
All conversion runs entirely in your browser. No data is sent to any server. Your JSON input is processed in memory and never persisted.
Frequently Asked Questions
How do I get XML attributes instead of child elements?
Prefix the JSON key with @. The pair "@id": "b1" becomes id="b1" on the surrounding element. A key named #text becomes that element's text content.
What happens to JSON arrays?
With array wrapping off, the array's key repeats once per item. With wrapping on, the items are nested inside the array key using the item element name you choose.
What if a JSON key is not a valid XML name?
Characters XML does not allow are replaced with an underscore, and a leading digit gets an underscore prefix. Every rename is listed under the output so nothing changes silently.
Is my data sent anywhere?
No. All conversion happens in your browser using standard JavaScript.
