YAML to XML Converter Online

What Is a YAML to XML Converter?

A YAML to XML converter transforms YAML configuration files and data documents into Extensible Markup Language format. YAML is the preferred configuration format for modern DevOps tooling, while XML remains the standard for enterprise integration, SOAP services, and many industry-specific data interchange formats. Converting between these formats is necessary when bridging modern infrastructure tools with legacy enterprise systems.

This converter first parses YAML into an intermediate JavaScript object representation using the js-yaml library, then recursively serializes that structure into well-formed XML with proper element nesting and indentation. YAML mappings become nested XML elements, sequences are represented as repeated elements, and scalar values become text content. Special characters are escaped to ensure valid XML output. The entire pipeline runs in your browser with zero server involvement, keeping your configuration data private.

How to Convert YAML to XML

1. Paste your YAML content into the input panel. Configuration files, data definitions, and any valid YAML document are accepted.
2. Click Convert to parse the YAML and generate a well-formed XML document with proper element hierarchy and indentation.
3. Review the XML output in the right panel. YAML mappings become nested elements, sequences become repeated elements, and scalars become text content.
4. Copy or download the XML file for use in enterprise systems, SOAP service integrations, or any platform that requires XML input.

Why Use PinusX YAML to XML Converter?

Integration engineers and DevOps professionals often need to convert YAML configurations into XML format for enterprise middleware, legacy SOAP services, and industry-standard data feeds. PinusX processes your YAML with 100% client-side conversion — your configuration files containing database credentials, API endpoints, and infrastructure secrets never leave your browser. After the November 2025 jsonformatter.org breach that leaked 80,000 credentials, using server-based conversion tools for infrastructure configuration is a significant security liability that PinusX completely eliminates.

Frequently Asked Questions

How are YAML sequences represented in XML?

YAML sequences (lists) are converted to repeated XML elements sharing the same tag name. For example, a YAML list under the key 'servers' produces multiple <servers> child elements, one for each list item. This is the standard convention for representing collections in XML.

Are YAML comments preserved in the XML?

No. YAML comments are discarded during parsing because the intermediate JSON representation does not support comments, and XML comments have different semantics. If you need to preserve annotations, add them manually to the XML output as XML comments.

Does this handle multi-line YAML strings?

Yes. YAML block scalars using pipe (|) or greater-than (>) notation are parsed into their full string content and placed as text content within the corresponding XML element. Line breaks and indentation are preserved according to YAML block scalar rules.

What root element name is used?

The converter uses 'root' as the XML root element name. All top-level YAML keys become child elements of this root element. You can rename the root element in the output if your target system requires a specific root element name.

Is this safe for DevOps configurations?

Completely safe. All YAML to XML conversion runs locally in your browser. Your infrastructure configurations, environment variables, database connection strings, and deployment secrets are never transmitted to any server during the conversion process.
