YAML to XML

Some systems only accept XML: SOAP services, enterprise integrations, older CMS imports, Android resources and many government and banking APIs. If your data or configuration is in YAML, this converter turns it into well-formed XML with matching structure.

How to use it

1. Paste YAML.
2. Copy the generated XML.

Example

YAML input:

invoice:
  number: INV-2026-0042
  customer: Asha Rao
  lines:
    - sku: A1
      qty: 2
    - sku: B7
      qty: 1

XML output:

<invoice>
  <number>INV-2026-0042</number>
  <customer>Asha Rao</customer>
  <lines>
    <sku>A1</sku>
    <qty>2</qty>
  </lines>
  <lines>
    <sku>B7</sku>
    <qty>1</qty>
  </lines>
</invoice>

Mapping rules

• Each key becomes an element; nested mappings become nested elements.
• Each list item becomes a repeated element with the list's key name.
• XML needs exactly one root element. If the YAML has several top-level keys, they are wrapped in a root element.
• Special characters such as & and < in values are escaped automatically.

Things to check

• Element names: XML names cannot start with a digit or contain spaces. Keys like 2fa or first name must be renamed.
• Attributes vs. elements: if the target schema expects attributes, such as <line sku='A1'/>, adjust the output or use the converter's attribute convention.
• Validation: validate the result against the receiving system's XSD schema before sending.
