Prefer scripting this in a pipeline? Here are the most common CLI and library approaches.
Python with dict2xml
from dict2xml import dict2xml
import json
xml = dict2xml(json.load(open('in.json')))
open('out.xml','w').write(xml)Node.js with xml-js
const xmljs = require('xml-js');
const json = require('./in.json');
const xml = xmljs.js2xml(json, { compact: true, spaces: 2 });Java (Jackson)
XmlMapper xml = new XmlMapper();
ObjectMapper json = new ObjectMapper();
JsonNode tree = json.readTree(new File("in.json"));
xml.writeValue(new File("out.xml"), tree);Frequently asked questions
Why do my array items become `<item>` tags?
XML elements require names, and JSON arrays don't provide one. We use `<item>` as a safe default. If your parent key is e.g. `books`, you can post-process the XML to rename `<item>` to `<book>` — or tell us in the options to singularize automatically.
How are attributes (`@foo`) handled?
If a JSON key starts with `@`, we emit it as an XML attribute on the parent element. So `{ "item": { "@id": "5", "name": "X" } }` becomes `<item id="5"><name>X</name></item>`. This follows the badgerfish / JsonML conventions most XML libraries already use.
Does it escape special characters correctly?
Yes. `<`, `>`, `&`, `'`, and `"` are escaped using standard XML entities (`<`, `>`, `&`, etc.) in text nodes and attribute values. The output is valid XML 1.0.
Can I add an XML namespace?
Include `"@xmlns": "http://example.org/schema"` on any object key; the converter emits it as a namespace declaration. For prefixed namespaces, use `"@xmlns:ns": "..."` and prefix child keys with `ns:`.
Is the output valid against an XSD schema?
We emit well-formed XML — not schema-valid XML. If you have an XSD you need to match, paste the result into our XML Validator to check conformance.
