Why convert JSON to XML?
JSON is native to JavaScript and most REST APIs, but sometimes you need XML instead — self-describing with schemas, namespaces, and attributes. This tool parses your JSON input, transforms the data structure, and serializes it as valid XML. The entire conversion runs in your browser’s JavaScript runtime with no server round-trip.
Steps
- 1Paste or type JSON into the left editor.
- 2Hit Convert.
- 3Read the XML output on the right. Copy it, or keep editing the source and convert again.
What’s included
- Accurate parsing — The JSON parser validates your input before conversion — you’ll see a clear error if the source is malformed.
- Syntax-aware editors — Both panels use
CodeMirrorwith language-specific highlighting for JSON and XML. - Offline processing — No data leaves your browser. The conversion uses client-side libraries with zero network calls.
JSON input → XML output
// JSON input:
{
"name": "Alice",
"age": 30,
"active": true
}
// Converted to XML:
<?xml version="1.0"?>
<root>
<name>Alice</name>
<age>30</age>
<active>true</active>
</root>Questions
Is any data sent to a server?
No. Parsing and serialization both happen in JavaScript inside your browser tab. There is no backend involved.
Can I go from XML back to JSON?
Yes — open the XML to JSON converter from the navigation menu. It uses the same parsing pipeline in reverse.
What happens if the input is invalid?
The parser will surface a specific error message explaining what’s wrong — missing bracket, unexpected token, etc. Fix the source and convert again.
