Free XML to YAML Converter — Transform XML Files Online

What Is XML to YAML?

If you've ever tried to write a Kubernetes manifest or Docker Compose file from an XML config, you know the pain — tags, namespaces, and angle brackets everywhere when you just want clean indented keys. This tool converts any XML into human-friendly YAML instantly. The YAML 1.2 spec defines the target format; yaml.org has the full reference. XML elements become YAML keys, nested elements become nested mappings, and repeated elements become sequences. The W3C XML spec defines the source format. Everything runs in your browser — your XML never touches a server. For browser XML parsing, see MDN DOMParser.

How to Use This Tool

Paste or Upload XML

Paste XML or upload a file. Use Sample for example data.

Review YAML Output

The right panel shows converted YAML. Elements become keys; attributes may be inlined or nested.

Copy or Download

Use Copy or Download. For JSON to YAML, use JSON to YAML. For XML formatting, use XML Formatter.

When XML to YAML Helps

When migrating from XML to YAML for Kubernetes, Docker Compose, or CI/CD, convert here. XML from SOAP, feeds, or enterprise APIs becomes human-friendly YAML.

Conversion Example

Example: Convert an XML config to YAML

XML input:

<config>
  <database>
    <host>localhost</host>
    <port>5432</port>
    <name>myapp</name>
  </database>
  <server>
    <port>8080</port>
    <debug>true</debug>
  </server>
</config>

YAML output:

config:
  database:
    host: localhost
    port: 5432
    name: myapp
  server:
    port: 8080
    debug: true

Frequently Asked Questions

When should I use YAML instead of XML?

YAML is better for human-edited config files — Kubernetes manifests, Docker Compose, Ansible playbooks, GitHub Actions. XML is still common for SOAP APIs, RSS feeds, Maven builds, and enterprise data exchange. If your tool outputs XML but your system needs YAML, convert here.

How does XML map to YAML?

XML elements become YAML keys, nested elements become nested mappings (indented), text content becomes the value, XML attributes are often inlined as sibling keys, and repeated sibling elements with the same tag become YAML sequences (lists).

Can I use this for Kubernetes or Helm chart migration?

Yes. Paste XML config — from Spring Boot XML beans, Maven settings, or legacy CI configs — and get YAML output you can clean up and adapt for Kubernetes or Helm. The converter handles nested structures and repeated elements automatically.

What happens with XML attributes during conversion?

XML attributes don't have a direct YAML equivalent. This tool adds them as sibling keys alongside the element's text content. You may need to adjust the output depending on your target schema.

Is my XML data sent to a server?

No. The entire conversion runs locally in your browser using JavaScript. Your XML never leaves your device — there's no server, no account, and no upload.
