How It Works

The converter parses YAML input using a robust YAML parser, validates the structure, and transforms it into a well-formed XML document while preserving the data hierarchy and types.

Steps

  1. Paste or upload your YAML content
  2. YAML is parsed and validated
  3. Data structure is analyzed and mapped
  4. XML structure is generated
  5. Output is formatted and validated
  6. Final XML document is produced

Limitations

  • Maximum file size: 10MB
  • YAML merge keys are flattened
  • Custom YAML tags not supported

Examples

Simple YAML to XML Conversion

Converting a basic YAML structure to XML

Input:

name: John Doe
age: 30
email: [email protected]
address:
  street: 123 Main St
  city: Boston
  country: USA

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>John Doe</name>
  <age>30</age>
  <email>[email protected]</email>
  <address>
    <street>123 Main St</street>
    <city>Boston</city>
    <country>USA</country>
  </address>
</root>

Frequently Asked Questions

How does YAML to XML conversion work?

The converter parses YAML input, preserves the hierarchical structure, and generates equivalent XML elements while maintaining data types and relationships.

Are YAML comments preserved in XML?

By default, YAML comments are converted to XML comments. This behavior can be toggled in the converter settings.

How are YAML arrays handled in XML?

YAML arrays are converted to repeated XML elements with appropriate parent-child relationships maintained.
