Bidirectional XML and YAML converter. Convert XML documents to YAML format and generate XML from YAML configuration.
Format Converter
About This Tool
The XML YAML Converter is a bidirectional tool that converts between XML documents and YAML configuration format. XML to YAML mode parses XML documents and converts them to clean, readable YAML. YAML to XML mode takes YAML configuration and generates well-formed XML documents. XML attributes are preserved as @attr keys, and repeated elements are properly handled as YAML sequences.
Key Features
- Bidirectional conversion between XML and YAML formats
- Preserves XML attributes with @attr notation in YAML
- Handles mixed content with #text node key
- Repeated child elements automatically become YAML sequences
- Configurable root element name and attribute prefix
- Completely local processing, no data leaves your browser
Use Cases
- Convert XML configuration files to YAML for easier editing
- Generate XML documents from YAML configuration templates
- Migrate data serialization between XML and YAML formats
- Transform API response formats between XML and YAML
- Bridge configuration between legacy XML systems and modern YAML-based tools

Frequently Asked Questions
What is the XML YAML Converter?
The XML YAML Converter is an online bidirectional converter that allows you to convert XML documents to YAML format and generate XML from YAML configuration. It runs entirely in your browser with no data sent to any server.
How are XML attributes represented in YAML?
XML attributes are represented as keys with the @ prefix in YAML. For example, an XML attribute id="123" becomes @id: "123" in the YAML output. This convention clearly distinguishes attributes from child elements.
How is mixed content (text and child elements) handled?
Mixed content is handled using a #text key for the text portion. When an XML element contains both text and child elements, the text is stored under #text and child elements remain as nested keys, preserving the complete content structure.
How are repeated XML elements converted to YAML?
Repeated XML elements with the same tag name are automatically converted to YAML sequences (lists). For example, multiple <item> elements become a single item: [...] list in YAML, preserving all entries in order.
Can I customize the root element name and attribute prefix?
Yes. The converter provides options to set the root element name when converting YAML to XML, and to configure the attribute prefix character when converting XML to YAML. The default prefix is @ but you can change it to suit your needs.
