How do I convert XML to YAML?

Paste your XML into the converter on this page and pick YAML as the output. Conversion happens instantly in your browser — nothing is uploaded. You can also call the free API: POST /api/v1/convert with { from: "xml", to: "yaml", data }.

Is the XML to YAML converter free?

Yes. The on-page XML-to-YAML converter is free and runs locally in your browser. The developer API is also free during beta, with a per-call paid tier for bulk and large payloads.

Convert XML to YAML

Paste your Extensible Markup Language (XML) and convert it to YAML Ain't Markup Language (YAML) in one click. Runs entirely in your browser — no upload, no signup.

Input (XML)

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <item>
    <id>1</id>
    <name>Ada Lovelace</name>
    <role>Engineer</role>
    <active>true</active>
  </item>
  <item>
    <id>2</id>
    <name>Alan Turing</name>
    <role>Researcher</role>
    <active>false</active>
  </item>
</root>

Output (YAML)

Convert this via the API (curl)

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"xml","to":"yaml","data":"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<root>\n  <item>\n    <id>1</id>\n    <name>Ada Lovelace</name>\n    <role>Engineer</role>\n    <active>true</active>\n  </item>\n  <item>\n    <id>2</id>\n    <name>Alan Turing</name>\n    <role>Researcher</role>\n    <active>false</active>\n  </item>\n</root>"}'

Free conversion API — no key during beta. POST { from, to, data }, get back the converted string. All conversion runs server-side; nothing is stored.

XML vs YAML

XML

A verbose, tag-based markup format common in enterprise systems, SOAP, RSS, and legacy feeds.

YAML

An indentation-based, comment-friendly format used heavily for config (Kubernetes, CI, Docker Compose).

How to convert XML to YAML

FormatForge parses your XML into an in-memory data structure, then serializes it as YAML. Numbers, booleans, and null values are preserved, and nested structures are mapped to YAML's native shape.

Example

XML in

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <item>
    <id>1</id>
    <name>Ada Lovelace</name>
    <role>Engineer</role>
    <active>true</active>
  </item>
  <item>
    <id>2</id>
    <name>Alan Turing</name>
    <role>Researcher</role>
    <active>false</active>
  </item>
</root>

YAML out

'?xml':
  '@_version': '1.0'
  '@_encoding': UTF-8
root:
  item:
    - id: 1
      name: Ada Lovelace
      role: Engineer
      active: true
    - id: 2
      name: Alan Turing
      role: Researcher
      active: false

Convert XML to YAML in code

Send the conversion to the free API and get the result back as a string:

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"xml","to":"yaml","data":"...your XML as a string..."}'

FAQ

Does converting XML to YAML change my data?: No — the conversion is structural. Your values are preserved; only the serialization format changes.
Is my data uploaded anywhere?: The on-page converter runs locally in your browser. The API processes your payload server-side and stores nothing.
