JSON → XML & YAML

Free Online JSON to XML / YAML Converter

Convert JSON to XML or YAML instantly — right in your browser, with no server involved.

JSON is the lingua franca of modern APIs, but XML and YAML remain widely used in configuration files, legacy systems, CI/CD pipelines, DevOps tooling, and enterprise integrations. Our free JSON to XML / YAML Converter bridges the gap without any server-side processing — your data stays on your device, always.

When Would You Need to Convert JSON to XML?

• Integrating with SOAP-based or legacy enterprise APIs that only accept XML
• Importing data into tools like Microsoft Excel, XSLT processors, or XML-based CMS platforms
• Generating Android resource files or Spring configuration files
• Working with RSS/Atom feeds, OPML, or SVG structures
• Transforming REST API responses for use with XML-native systems

When Would You Need to Convert JSON to YAML?

• Writing Kubernetes manifests, Helm charts, or Docker Compose files
• Creating GitHub Actions, GitLab CI, or CircleCI pipeline configurations
• Editing Ansible playbooks or Salt Stack states
• Setting up configuration files for tools like ESLint, Prettier, Jest, or Webpack
• Making JSON data more human-readable for documentation or review

XML vs YAML — Which Should You Choose?

How to Convert JSON in 3 Steps

1. Paste your JSON object or array into the input panel on the left.
2. Choose XML or YAML as the output format. For XML, optionally set a custom root tag name.
3. Click Convert — or just type and watch the output update live. Then Copy or Download your result.

Real Example — JSON to XML

JSON Input:

{
  "user": {
    "id": 1,
    "name": "Alice Johnson",
    "email": "alice@example.com",
    "active": true,
    "tags": ["admin", "editor"]
  }
}

XML Output:

<root>
  <user>
    <id>1</id>
    <name>Alice Johnson</name>
    <email>alice@example.com</email>
    <active>true</active>
    <tags>admin</tags>
    <tags>editor</tags>
  </user>
</root>

Real Example — JSON to YAML

YAML Output (same JSON):

user:
  id: 1
  name: Alice Johnson
  email: alice@example.com
  active: true
  tags:
    - admin
    - editor

Key Features

• Convert JSON to XML or YAML with one click
• Custom XML root tag name (root, data, response, or your own)
• Choose 2-space, 4-space, or tab indentation
• Live preview as you type
• Copy to clipboard or download as .xml / .yaml
• Handles nested objects, arrays, nulls, booleans, and numbers
• 100% browser-based — zero server calls
• Works on desktop and mobile

Pro Tips

• Use a meaningful XML root tag for better readability (e.g. <users> instead of <root>)
• For Kubernetes configs, always use YAML — it supports comments and is the standard
• Use JSON Validator first to ensure your input is valid before converting
• YAML output from this tool is compatible with PyYAML, js-yaml, and Go's yaml.v3
• XML arrays are expanded into repeated sibling elements (the standard XML pattern)
