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 the XML to YAML Converter

  1. Paste or enter your input into the text field.
  2. Configure any options (format, delimiter, encoding, or mode) using the controls above the output.
  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.

Convert XML into YAML — the format used by Kubernetes manifests, Ansible playbooks, and most modern config files. The converter parses the XML with the browser’s DOMParser, then emits YAML with each element as a mapping key. Repeated children collapse into YAML sequences, and attributes are preserved under @-prefixed keys to avoid colliding with child element names.

How the XML to YAML Converter Works

When an element has both attributes and text content, the text lives under #text alongside the @-prefixed entries (the standard convention shared with XML→JSON converters). Strings that could be misread by a YAML parser — numbers, dates, booleans, anything with a colon or hash — are auto-quoted; plain strings stay unquoted for readability.

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.
