YAML To XML

What is YAML to XML Conversion?

YAML is a lightweight data format commonly used in configuration files and application settings. XML, while more verbose, is widely used in legacy systems, SOAP-based APIs, and enterprise-grade systems.

This tool helps convert YAML structures into valid XML—preserving hierarchy and values—without manual transformation or external scripts.

Example 1: Simple Key-Value Mapping

YAML Input:

name: Alice
age: 30

XML Output:

<root>
  <name>Alice</name>
  <age>30</age>
</root>

Great for converting straightforward YAML configs to XML format.

Example 2: Nested Structure

YAML Input:

person:
  name:
    first: John
    last: Doe
  age: 35

XML Output:

<root>
  <person>
    <name>
      <first>John</first>
      <last>Doe</last>
    </name>
    <age>35</age>
  </person>
</root>

Use this when dealing with hierarchical data like profiles or configuration files.

Example 3: YAML List

YAML Input:

users:
  - name: Jane
    age: 28
  - name: Mike
    age: 31

XML Output:

<root>
  <users>
    <name>Jane</name>
    <age>28</age>
  </users>
  <users>
    <name>Mike</name>
    <age>31</age>
  </users>
</root>

Lists in YAML are represented as repeated XML elements — ideal for data entries or multiple objects.

Example 4: YAML with Boolean and Null

YAML Input:

active: true
disabled: false
pending: null

XML Output:

<root>
  <active>true</active>
  <disabled>false</disabled>
  <pending/>
</root>

YAML booleans and nulls are preserved and correctly translated into XML — useful for status flags or feature toggles.

Example 5: YAML with Special Characters

YAML Input:

title: "Learning & Development"
description: "Train employees in <coding>, testing & automation."

XML Output:

<root>
  <title>Learning &amp; Development</title>
  <description>Train employees in &lt;coding&gt;, testing &amp; automation.</description>
</root>

Special characters are automatically escaped in XML — essential for rendering safe and valid markup.

How It Works

1. Paste your YAML content or upload a .yaml file

2. Click Convert to XML

3. Copy or download your XML instantly—no downloads or uploads involved

Everything runs locally in your browser for speed and privacy.

Use Cases

• API Payload Transformation: Convert YAML used in dev environments into XML for enterprise or SOAP-based APIs

• Configuration Migration: Switch configuration formats for older systems

• Data Reformatting: Clean and convert YAML data for legacy applications

• Combine with XML to JSON for nested pipeline support

• Use YAML to JSON or YAML to CSV for alternate flat or structured outputs

Pro Tips

• Wrap top-level lists in a root node when converting to ensure well-formed XML

• Use consistent indentation (2 spaces) in YAML to avoid structure errors

• You can reprocess the XML output through XML to YAML for round-trip verification

• Combine with YAML to JSON to support systems using both formats

• All conversions happen securely in your browser—no backend processing or data leaks
