About XML to YAML Converter

Convert XML data to YAML (YAML Ain't Markup Language) format, a human-readable data serialization format used for configuration files, data exchange, and more.

Key Features

  • Automatic Type Detection: Recognizes strings, integers, floats, booleans, dates, and null values
  • Block & Flow Styles: Choose between readable block style or compact flow style
  • Custom Indentation: Configure indent size (2-8 spaces)
  • Comments: Optional comment headers and item labels
  • Key Sanitization: Converts XML tags to valid YAML keys
  • File Upload: Upload .xml files directly
  • Copy & Download: Easy export as .yaml or .yml file

How to Use

  1. Input XML Data: Paste your XML data or upload an .xml file
  2. Configure Options: Choose indentation, style, and comment preferences
  3. Review Output: The YAML data generates automatically
  4. Copy or Download: Use the Copy or Download button to save your YAML file

YAML Styles

  • Block Style (Default): Multi-line, readable format with proper indentation
  • Flow Style (Compact): Inline JSON-like syntax for compact representation

Example Conversion

XML Input:

<?xml version="1.0" encoding="UTF-8"?>
<employees>
  <employee>
    <name>Alice Johnson</name>
    <position>Software Engineer</position>
    <salary>95000</salary>
    <active>true</active>
  </employee>
  <employee>
    <name>Bob Smith</name>
    <position>Product Manager</position>
    <salary>105000</salary>
    <active>true</active>
  </employee>
</employees>

YAML Output (Block Style):

employees:
  - # Item 1
    name: Alice Johnson
    position: Software Engineer
    salary: 95000
    active: true
  - # Item 2
    name: Bob Smith
    position: Product Manager
    salary: 105000
    active: true

YAML Output (Flow Style):

employees:
  - {name: Alice Johnson, position: Software Engineer, salary: 95000, active: true}
  - {name: Bob Smith, position: Product Manager, salary: 105000, active: true}

Common Use Cases

  • Configuration Files: Docker Compose, Kubernetes, Ansible, CI/CD pipelines
  • Data Exchange: API responses, data serialization
  • Documentation: OpenAPI/Swagger specifications
  • Infrastructure as Code: CloudFormation, Terraform
  • Application Config: Rails, Spring Boot, and other frameworks

Type Detection

The converter automatically detects and formats data types:

  • Strings: Quoted if they contain special characters
  • Integers: Whole numbers without quotes (e.g., 42)
  • Floats: Decimal numbers without quotes (e.g., 3.14)
  • Booleans: true or false (case-insensitive input)
  • Dates: ISO 8601 format (e.g., 2024-01-15)
  • Null: Empty values become null

YAML Benefits

  • Human-Readable: Clean, intuitive syntax
  • Minimal: Less verbose than XML or JSON
  • Comments: Native support for comments
  • Type-Safe: Automatic type inference
  • Widely Supported: Used by many modern tools and frameworks
  • Flexible: Supports complex data structures

Privacy & Security

All conversions happen locally in your browser. Your XML data is never uploaded to any server, ensuring complete privacy and security.
