What is XML to JSON Schema Converter?

This tool converts an XML document structure into a JSON Schema (draft-07) document. JSON Schema is a standard for describing the structure and validation rules of JSON data, defined at json-schema.org. The converter walks the XML DOM tree, infers data types (string, number, boolean, object, array), and generates a valid JSON Schema with properties, types, and required fields.

The tool supports both plain XML and XSD (XML Schema Definition) as input. For plain XML it infers the schema from the document structure. For XSD it parses xs:element, xs:complexType, and xs:simpleType declarations. All processing is browser-based using the native DOMParser API. Your data never leaves your device.

How to Convert XML to JSON Schema

Follow these steps to generate a JSON Schema from your XML.

Paste or Upload XML

Paste your XML or XSD into the Input XML panel, or click Upload to load a file. Click Sample to load example XML.

View Generated Schema

The JSON Schema Output panel shows the generated JSON Schema instantly. Types are inferred from element content: numeric text becomes number, true/false becomes boolean, nested elements become objects, repeated elements become arrays.

Download or Copy

Click Download to save the schema as a .json file, or Copy to copy it to your clipboard.

When You'd Actually Use This

API Documentation

Convert your XML data structures to JSON Schema to document your REST API request and response bodies using tools like OpenAPI / Swagger.

Data Validation Setup

Generate a JSON Schema from sample XML to use as a validation baseline for JSON data that mirrors your XML structure.

Schema Migration

Migrating from XML-based systems (SOAP, XSD) to JSON-based APIs? Generate a starting JSON Schema from your existing XSD files.

Code Generation

Use the generated JSON Schema as input to code generators that produce TypeScript interfaces, Java classes, or other language models.

Frequently Asked Questions

Is my XML data stored?

No. Everything happens in your browser. Your XML never leaves your device.

What JSON Schema draft does it generate?

The tool generates JSON Schema draft-07, which is widely supported. See the draft-07 specification.

How are XML attributes handled?

XML attributes are mapped to properties in the JSON Schema with type "string" by default.

How does it detect arrays?

Repeated XML elements with the same tag name at the same level are inferred as arrays.

Does it support XSD input?

Yes — paste an XSD document and the converter will parse xs:element and xs:complexType declarations to generate a JSON Schema.
