About YAML (YAML Ain't Markup Language)

YAML is a human-friendly data serialization language designed for readability and ease of use. It uses minimal punctuation and relies on indentation to represent structure, making it ideal for configuration files, data exchange, and documentation.

YAML is more readable than JSON or XML for many use cases and has become popular in DevOps, containerization (Docker, Kubernetes), and infrastructure-as-code tools. It supports lists, mappings, and scalar values with a clean, intuitive syntax.

About XML (Extensible Markup Language)

XML is a markup language designed to store and transport data. It focuses on what data is, using descriptive tags to define both the structure and content. XML documents are human-readable and widely used for configuration files, web services, and data exchange.

XML uses a hierarchical structure with nested elements, attributes, and text content. Each XML document must have a root element, and elements can contain other elements, creating a tree-like structure. XML is the foundation for many enterprise systems and data exchange protocols.

Example (from YAML above):
<?xml version="1.0" encoding="UTF-8"?>
<store>
  <name>TechStore</name>
  <location>New York</location>
  <products>
    <product id="1">
      <name>Laptop</name>
      <price>999.99</price>
      <inStock>true</inStock>
    </product>
    <product id="2">
      <name>Mouse</name>
      <price>29.99</price>
      <inStock>true</inStock>
    </product>
  </products>
</store>

How to Use This Converter

  1. Prepare your YAML: Paste your YAML document into the input area. Ensure proper indentation using spaces (not tabs) - YAML is very sensitive to indentation.
  2. Convert: Click the "Convert to XML" button to transform your YAML data.
  3. Review: The converted XML will appear in the output area with proper formatting and XML declaration.
  4. Copy or Download: Use the "Copy" button to copy the result to your clipboard, or click "Download" to save as an XML file.
  5. Use the XML: Integrate the XML into your web services, configuration systems, or data processing pipeline.

Important Notes

YAML Indentation:

YAML is highly sensitive to indentation. Use 2 spaces (not tabs) for each indentation level. Incorrect indentation will cause conversion errors.

Data Types:

YAML interprets unquoted values like 'true', 'false', and numeric values as their respective types. Use quotes to treat values as strings.

Lists in YAML:

YAML lists (starting with '-') are converted to multiple XML elements with the same tag name.

XML Root Element:

Your YAML must have a root-level key that becomes the XML root element. The converter will fail if there's no root element.
