Why convert XML to YAML?
XML is self-describing with schemas, namespaces, and attributes, but sometimes you need YAML instead — human-friendly, supports comments and anchors. This tool parses your XML input, transforms the data structure, and serializes it as valid YAML. The entire conversion runs in your browser’s JavaScript runtime with no server round-trip.
Steps
- 1Paste or type XML into the left editor.
- 2Hit Convert.
- 3Read the YAML output on the right. Copy it, or keep editing the source and convert again.
What’s included
- Accurate parsing — The XML 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 XML and YAML. - Offline processing — No data leaves your browser. The conversion uses client-side libraries with zero network calls.
XML input → YAML output
// XML input:
<?xml version="1.0"?>
<root>
<name>Alice</name>
<age>30</age>
<active>true</active>
</root>
// Converted to YAML:
name: Alice
age: 30
active: trueQuestions
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 YAML back to XML?
Yes — open the YAML to XML 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.
