FAQ

Does this tool validate the generated XML against the XSD?

No. It generates a best-effort sample instance based on common XSD constructs; use an XML validator if you need strict validation.

Which XSD features are supported?

Common ones: global elements, named/inline complexType, sequence/all/choice (first option), attributes, and simpleType restrictions with enumerations.

Can it generate multiple items for maxOccurs or unbounded?

To keep output small, it generates a single instance per element even if maxOccurs is greater than 1.

How are values chosen for xs:string, xs:int, xs:boolean, dates, etc.?

It uses deterministic placeholders (e.g., example, 0, false, 2000-01-01) so outputs are predictable.

Does it handle namespaces and qualified elements?

The generator keeps output simple and typically omits namespaces; if your schema requires strict qualification, validate and adjust the instance as needed.

Is my XSD sent to a server?

No. The parsing and generation run locally in your browser (no network calls from the tool).

Why are some optional elements missing?

By default, elements with minOccurs="0" (and non-required attributes) are omitted; enable Include optional to add them.
