YAML to XML
Free online YAML to XML converter. Paste YAML and instantly get well-formatted XML output with support for nested objects, arrays, and custom root elements.
How does YAML to XML conversion work?
YAML keys become XML element tags, and values become element text content. Nested YAML objects are recursively converted into nested XML elements. Arrays are wrapped in repeated elements using the parent key name.
What YAML features are supported?
The converter supports objects (maps), arrays (sequences), strings, numbers, booleans, null values, and nested structures of arbitrary depth. Multi-line strings are also handled correctly.
What is the root element of the generated XML?
By default, the root element is named <root>. You can customize the root element name through the settings panel to match your specific XML schema requirements.
How are arrays handled in the conversion?
YAML arrays are converted to repeated XML child elements. For example, a YAML list 'items: [a, b]' becomes <items>a</items><items>b</items> in the XML output.
Is this tool free to use?
Yes, this YAML to XML converter is completely free. There are no usage limits, no registration required, and no data is sent to any server. All conversion happens locally in your browser.
Can I convert large YAML files?
Yes, the converter handles large YAML files efficiently. Since all processing is done client-side in your browser, there are no file size limits imposed by the tool.
What is the difference between YAML and XML?
YAML is a human-friendly data serialization format that uses indentation and minimal syntax. XML is a markup language that uses tags and attributes. YAML is more concise, while XML is more verbose but widely used in enterprise systems.
Does the converter validate YAML input?
Yes, the converter parses and validates your YAML input in real time. If there are syntax errors, you will receive an error message indicating the issue so you can correct it.
Is my data safe when using this tool?
Absolutely. All YAML to XML conversion is performed entirely in your browser using JavaScript. No data is transmitted to any server, ensuring complete privacy and security of your configuration files.
Can I use this tool offline?
Once the page is loaded, the conversion functionality works without network access since all processing is client-side. However, you need an initial internet connection to load the page.
How are special characters handled?
Special XML characters such as <, >, &, ', and " are automatically escaped in the XML output to ensure the generated XML is well-formed and valid.
What programming languages use YAML and XML?
YAML is widely used in DevOps tools (Docker, Kubernetes, Ansible), while XML is common in enterprise Java, .NET, SOAP web services, and configuration files across many platforms.
