Online XML to XSD Schema Converter

Convert your XML documents into valid XSD (XML Schema Definition) structures instantly. XSD Generator is a free online XML to XSD schema converter and generator that automatically analyzes the hierarchy, elements, attributes, and data types of your raw XML input to generate a precise, standards-compliant XSD blueprint. Everything runs entirely in your browser — no upload, no signup, and your data never leaves the page.

How to Convert XML to XSD

  1. Paste your code: Copy your raw XML payload and paste it directly into the code editor on the left, or click Load sample to try a ready-made document.
  2. Generate the schema: The converter infers element types, attributes, and occurrence rules automatically as you type. Click Convert or press Ctrl/⌘ + Enter to re-run the analysis.
  3. Refine the types: Use the Type Definitions panel to switch the inferred interpretation (Enum, Pattern, Range, or List), edit values, regex, or bounds, and the XSD regenerates live.
  4. Copy the XSD: Review the generated XML Schema Definition in the output panel on the right and click Copy XSD to copy it to your clipboard.

Conversion is live — every edit to the XML regenerates the schema, so you can iterate quickly without re-uploading or re-running a command-line tool.

What is the Difference Between XML and XSD?

While XML (eXtensible Markup Language) is used to store and transport data, an XSD (XML Schema Definition) acts as the rulebook for that data. An XSD defines the exact elements, attributes, data types, and structural orders that an XML document must follow to be considered valid.

Using an XSD generator ensures that your automated systems, APIs, and configuration files communicate without format errors by establishing strict data validation boundaries. This online XML schema converter inspects the structure of your document and produces a schema that matches it, so you can validate other documents against the same contract without writing boilerplate.

What This Online XSD Schema Converter Detects

  • Simple types: xs:string, xs:integer, xs:decimal, xs:boolean, xs:date, and xs:dateTime.
  • Occurrence constraints from repeated siblings (maxOccurs="unbounded") and optional elements (minOccurs="0").
  • Attributes with use="required" or use="optional".
  • Mixed content elements modelled with xs:simpleContent.
  • Named simpleType definitions for Enum, Pattern, Range, and List interpretations.

Example Conversion Map

An input structure like <user><id>1</id></user> will automatically map to an XSD complex element, declaring the inner child node configurations cleanly and accurately. Repeated siblings become unbounded sequences, and text-plus-attribute elements use xs:simpleContent extensions.

Why Use an Online XML Schema Converter?

Generating an XSD schema by hand is tedious and error-prone. An online XML converter inspects the structure of your document and produces a schema that matches it, so you can validate other documents against the same contract without writing boilerplate. Because this tool runs 100% client-side, it is safe to use even with sensitive documents — your XML never leaves your browser.
