Which JSON Schema specifications are supported?

The visualizer renders JSON Schema Draft-04, Draft-07, Draft 2019-09, and Draft 2020-12, including allOf, anyOf, oneOf, $defs, and nested object definitions.

Can this tool generate sample mock JSON from a schema?

Yes. Click the Generate Mock Data button to produce a valid JSON instance conforming to all required properties, types, patterns, and enum constraints.

Are my private enterprise schemas kept secure?

Yes. All schema parsing and tree rendering occur 100% locally inside your web browser. No schema data is ever transmitted to an external server.

Demystifying JSON Schema Hierarchies

JSON Schema provides a powerful contract for validating incoming REST API bodies, configuration files, and database records. However, large enterprise schemas spanning hundreds of lines with nested properties, definitions, and validation rules quickly become impossible to comprehend in raw JSON.

The JSON Schema Viewer transforms dense JSON Schema files into an intuitive, color-coded interactive documentation tree highlighting field names, primitive types, required flags, pattern regexes, and allowed enum values.

Visual Indicators

Type Badges: Easily differentiate strings, numbers, booleans, arrays, and objects at a glance.
REQUIRED Badge: Highlights required fields mandated by the parent schema.
Validation Constraints: Displays minimum, maximum, minLength, pattern, and enum restrictions cleanly below each field.

Frequently Asked Questions

Can I use this with OpenAPI / Swagger parameter schemas?

Yes! Simply copy the schema: { ... } block from your OpenAPI 3.0 or Swagger 2.0 definition, and the visualizer will render all components seamlessly.

How does Mock Data generation work?

The mock generator inspects property types, titles, formats (e.g. date-time, email), and enums to synthesize a compliant sample JSON instance conforming to your validation contract.
