About YAML to XML conversion

YAML is the format of choice for configuration — Kubernetes manifests, Docker Compose, GitHub Actions, Ansible playbooks — it supports comments and multi-document files that JSON doesn’t. XML is still the standard for RSS/Atom feeds, SOAP APIs, and Office file formats under the hood — features like attributes and XSD schema validation go beyond what JSON's plain key-value model can express.

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 YAML to XML

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

Example

Input (YAML):

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

Output (XML):

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>Ada Lovelace</name>
  <role>Mathematician</role>
  <active>true</active>
  <skills>math</skills>
  <skills>programming</skills>
</root>

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.
