Convert XML to YAML Online

Moving configuration from XML-based tools to YAML-based ones? This converter turns XML into idiomatic YAML in one step. It keeps attributes, turns repeated elements into lists, and quotes any value YAML might misinterpret.

Features

  • Readable output

    Nested elements become indented YAML mappings, and repeated elements become lists.

  • Attributes included

    Attributes are kept as @-prefixed keys, so no information from the XML is lost.

  • Type detection

    Optionally turn numeric and true/false values into YAML numbers and booleans.

  • Safe quoting

    Strings that YAML would misread, such as yes, no, or dates, are quoted automatically.

  • Strict validation

    Malformed XML is reported with the exact line and column before conversion.

  • Private by design

    The conversion runs entirely in your browser. Your data is never uploaded.

Frequently Asked Questions

Why convert XML to YAML?

YAML is easier to read and edit than XML and is the standard for tools like Kubernetes, Docker Compose, Ansible, and CI pipelines. Converting XML configs to YAML is common when migrating to these tools.

How are attributes represented in YAML?

Attributes become keys starting with @, for example "@env": production. They are quoted because @ has a special meaning at the start of a YAML value.

How are repeated elements converted?

Elements with the same name inside one parent become a YAML list. A single element becomes a plain value.

Is my XML uploaded anywhere?

No. The converter runs entirely in your browser using JavaScript. Your XML never leaves your device.
