JSON to XML Converter

How to convert JSON to XML

1. Paste JSON or open a file. The XML updates as you type.
2. Set Root (default root), switch XML declaration on or off, and pick the Indent.
3. Press ⇄ to check the round trip in XML to JSON.

Invalid JSON stops with the line and column of the mistake. JSON repair removes comments and trailing commas in one click; common JSON errors covers the rest.

Example

{
  "invoice": {
    "@number": "INV-77",
    "customer": "Kai Tanaka",
    "lines": [
      { "item": "Hosting", "amount": 20 },
      { "item": "Domain", "amount": 12 }
    ],
    "2fa enabled": true,
    "notes": null
  }
}

<?xml version="1.0" encoding="UTF-8"?>
<invoice number="INV-77">
  <customer>Kai Tanaka</customer>
  <lines>
    <item>Hosting</item>
    <amount>20</amount>
  </lines>
  <lines>
    <item>Domain</item>
    <amount>12</amount>
  </lines>
  <_2fa_enabled>true</_2fa_enabled>
  <notes/>
</invoice>

The note under the output lists 2fa enabled as renamed.

How the mapping works

• Root. An object with a single key, like invoice, uses that key as the root and ignores Root. Several top-level keys, a top-level array or a lone value are wrapped in the Root name; array items become <item> elements.
• Attributes and text. @number became number="INV-77", and a #text key becomes the element’s text, matching what XML to JSON produces.
• Arrays. Each item becomes an element named after the key, so <lines> appears twice. For a wrapper, nest it: {"lines": {"line": [...]}} gives one <lines> with two <line> children. An empty array becomes an empty element such as <tags/>, and an array inside an array is wrapped in <item> elements.
• Empty values. null and {} become an empty element such as <notes/>.
• Names. A name cannot start with a digit or contain spaces, so 2fa enabled became _2fa_enabled; symbols such as $ and / also become _.
• Escaping. <, & and " in values are written as <, & and ".
