Generate sample XML from an XSD schema

Constructing a valid sample XML message from an XSD by hand is tedious and error-prone. This tool reads your schema and generates a well-formed sample document with type-appropriate placeholder values for every element and attribute. The result is immediately usable as a starting point for testing SOAP services, validating parsers, or onboarding to a new XML-based integration.

Every xs:element defined in the schema appears in the output. Built-in types like xs:date produce "2024-01-01", xs:boolean produces "true", xs:anyURI produces "https://example.com". Enumeration values use the first declared option. Required xs:attribute entries are included; optional ones are included with a placeholder so you can see the full structure.

Who generates XML from XSD?

This pattern is most common in regulated industries where the schema is the authoritative specification and you must conform to it exactly.

Fintech: ISO 20022, FpML, and SWIFT MX schemas define payment, settlement, and derivatives messages. Generating a sample message is the first step in any integration.
Healthcare: HL7 v3, C-CDA, and FHIR XML schemas define clinical documents. Generate a sample to understand the structure before writing a parser.
Government: IRS, HMRC, and other tax authorities publish XSD schemas for electronic filings. Generate a sample before implementing the submission client.
Supply chain: PEPPOL, UN/EDIFACT, and GS1 XML schemas define order and invoice formats. Generating samples accelerates partner onboarding.

Capabilities

Everything in the XSD to XML Converter

Free XSD to XML generator. Paste any XSD schema and get a well-formed sample XML document with type-correct values for every element and attribute.

Sample generation

Produces well-formed, indented XML with realistic sample values for every element and attribute.

All XSD types

xs:string, xs:integer, xs:decimal, xs:boolean, xs:date, xs:dateTime, xs:anyURI all get appropriate sample values.

Attribute support

xs:attribute definitions are included in the sample output with their inferred type values.

Enumeration-aware

xs:enumeration values are sampled from the first defined option, not a generic placeholder.

Frequently asked questions

It reads your XSD schema and generates a sample XML document that matches the schema's structure. Every element and attribute defined in the schema appears in the output with a type-appropriate value — empty string, 1, true, 2024-01-01, etc. The result is ready to validate against the original XSD.

Developers integrating with SOAP APIs, HL7/FHIR feeds, ISO 20022 payment messages, or government e-submission schemas often receive only an XSD and need to construct a sample message to understand the format and begin testing. This tool automates that bootstrapping step.

The output is structurally correct — every required element and attribute is present. However, xs:restriction facets (like minLength, pattern, minInclusive) are not enforced in the sample values, so validation against a strict XSD may flag those. Use the sample as a starting point and adjust constrained fields.
