About XML to YAML conversion

XML is the long-standing format for SOAP web services, Office document internals (docx/xlsx), and schema-validated enterprise data exchange — its attribute and namespace support has no direct JSON equivalent. YAML is what most infrastructure-as-config tools use under the hood, from Kubernetes manifests to CI pipeline definitions — its comment support and multi-document format are things JSON simply lacks.

YAML has no native attribute syntax, so this tool uses the same "@name" key convention as the JSON/XML converter — an XML attribute becomes an @-prefixed YAML key instead of disappearing, and converts back cleanly.

How to convert XML to YAML

  1. Paste your XML into the left editor, or click sample above it to try example data.
  2. Click Convert. The YAML result appears on the right instantly.
  3. Click copy to copy the result, or download to save it as a file.

Example

Input (XML):

<person>
  <name>Ada Lovelace</name>
  <role>Mathematician</role>
  <active>true</active>
  <skills>math</skills>
  <skills>programming</skills>
</person>

Output (YAML):

person:
  name: Ada Lovelace
  role: Mathematician
  active: 'true'
  skills:
    - math
    - programming

Frequently asked questions

How are XML attributes represented in YAML? As an "@name" key, the same convention this tool's JSON/XML converter uses — since YAML has no native attribute syntax either, an @-prefixed key is the least lossy way to carry an XML attribute across formats.
Do I need to create an account? No. There's no signup, login, or account required — paste your data and click Convert.
Is there a file size limit? There's no hard-coded limit, but very large inputs (multi-megabyte files) can slow down or briefly freeze the tab while converting. For big files, converting in smaller chunks works better.
Why did my conversion fail? Check the status line under the Convert button — it reports the exact line and column where the parser stopped, and the input editor highlights that line in red so you can jump straight to it.
