Online XML to Schema Converter (XSD)

Paste an XML document and generate an XSD (XML Schema) instantly—offline in your browser. This tool infers common data types (string, integer, decimal, boolean, date/dateTime), includes attributes, and marks repeated child elements as maxOccurs="unbounded".

Runs locally. Nothing is uploaded.
 
XSD output Tip: this is a baseline schema inferred from one XML sample—review optional/required fields.
Privacy: runs locally in your browser. No uploads, no tracking scripts.

How to use

Use this converter to generate a baseline XSD from a representative XML sample.

  1. Paste your XML into the input box.
  2. Choose whether to infer data types.
  3. Click Convert → XSD.
  4. Copy or download the generated schema, then refine constraints as needed (optional/required fields, patterns, enums).

FAQ

What does this XML to schema converter generate?

It generates an XSD (XML Schema) based on the structure of your pasted XML sample, including child elements and attributes.

How does type inference work?

The tool infers common types from text values (integer, decimal, boolean, date, dateTime); anything else becomes xsd:string.

Does it support XML namespaces?

It uses each node’s local name and ignores namespace prefixes for simplicity, so you may need to add target namespaces manually afterward.

How are repeating elements handled?

If multiple sibling elements with the same name appear in your sample, the schema uses maxOccurs="unbounded" for that element.

Will it mark optional vs required fields correctly?

No—without multiple samples it can’t reliably infer optionality, so it defaults to a baseline structure you can refine.

Is my XML uploaded to a server?

No. Conversion runs locally in your browser; the JavaScript does not make network requests.

Why might the generated XSD not validate all real XML files?

The schema is inferred from one example and won’t capture all real-world variations, constraints, enums, or conditional rules.
