JSON to XML

How the JSON to XML works

The converter parses your JSON with a strict parser and writes the whole document inside one root element, named root unless you choose another name. Each object property becomes a child element with the property name, and strings, numbers and booleans become the element text. Numbers are copied exactly as written.

Arrays inside an object can be written in two ways. Repeat writes one element per item with the property name, for example <tags>a</tags><tags>b</tags>. Wrap writes a single <tags> element that contains one child per item, named item by default. Items of a top-level array and of arrays nested directly in arrays always use the item element name. null, empty objects and empty arrays become self-closing elements such as <note/>.

Property names that are not valid XML element names are changed: characters that are not allowed become _, and a name that starts with a digit, -, . or the reserved letters xml gets a leading _, so first name becomes first_name and 1st becomes _1st. In text, &, < and > are escaped, carriage returns are written as 
, and control characters that XML 1.0 cannot contain are replaced with U+FFFD. The status message tells you when either change was made.

How to use the JSON to XML

1. Paste your JSON into the input box, open a .json file, or select Load example.
2. Set the root element name, choose how arrays are represented and the array item element name, pick the indentation, and tick or untick Add XML declaration.
3. Select Convert to XML, or press Ctrl + Enter (Cmd + Enter on a Mac).
4. Copy the XML or download it as an .xml file. The status message tells you if any element names had to be changed.

Example

This input:

{"id": 7, "name": "Tom & Jerry", "tags": ["a", "b"], "address": {"city": "Oslo"}, "note": null}

is converted with the default options to:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <id>7</id>
  <name>Tom &amp; Jerry</name>
  <tags>a</tags>
  <tags>b</tags>
  <address>
    <city>Oslo</city>
  </address>
  <note/>
</root>

With Wrap items in child elements, the tags are written as:

  <tags>
    <item>a</item>
    <item>b</item>
  </tags>

Common use cases

• Sending data from a JSON API to a SOAP service or another system that only accepts XML.
• Creating XML test data or configuration files from existing JSON samples.
• Feeding JSON data into XSLT transformations or XML-based reporting tools.
• Comparing how the same data looks in JSON and XML when designing an integration.
