About XML to YAML

This tool parses an XML document in the browser and converts its structure to YAML using the js-yaml library. Element attributes are prefixed with @. Nested elements become nested YAML mappings. All processing happens in your browser - no data is sent to a server.

How to Use This Free Online XML Mapping Tool

  1. Paste your XML document or fragment into the input area.
  2. Adjust any available options shown - the output updates as you type.
  3. The result updates instantly - no submit button required for most operations.
  4. Click Copy or Download to take the output to your next step.

XML to YAML Converter: convert XML documents to YAML format instantly for use in Kubernetes manifests, Ansible playbooks, and modern configuration management. This utility acts as a precise xml mapping tool, transforming hierarchical tag structures into clean mapping keys and sequences. Whether you're migrating legacy enterprise data or prepping a cloud-native deployment, our engine ensures high-fidelity conversion with proper indentation and type coercion.

Advanced XML Tree to YAML Transformation

Our devops data utility expertly manages complex structures, automatically collapsing repeated child elements into YAML sequences while preserving attributes with standard @-prefixed keys. It serves as a robust kubernetes manifest converter, ensuring that strings containing special characters are correctly quoted to maintain valid YAML syntax. The entire process runs locally in your browser, providing a secure ansible inventory tool that keeps your data private while delivering production-ready output.

Frequently Asked Questions

How are repeated children represented?

Two or more siblings with the same name become a YAML sequence (- ). A single child stays a scalar mapping. Force-sequence mode is available when downstream consumers expect a list even of one item.

How are attributes kept distinct from child elements?

They are prefixed with @ (e.g. "@id": 3) so they don’t clash with same-named child elements. When an element has both attributes and text content, the text lives under the "#text" key.

Are values automatically quoted?

Yes when needed. Strings that look like booleans (yes, no, on, off), numbers, dates, or contain special YAML characters (:, #, [, ]) are quoted to prevent the parser misreading them. Plain strings are left unquoted for readability.

Is the XML uploaded anywhere?

No - parsing uses the browser’s DOMParser and emission is local string assembly.
