Generate JSON Schema Automatically


What is JSON Schema?

JSON Schema describes your JSON data format. It defines what fields are required, what data types they expect (string, integer, boolean), and other validation rules.


Auto-Generation Workflow

Writing schema by hand is tedious. Instead:

1. Paste your "Golden Master" JSON example representing a valid object.

2. The tool infers the schema structure.

3. It detects types (e.g., ISO dates) and required fields.

4. Copy the resulting **Draft-07** schema for use in your backend validators.


Use Cases

  • API Documentation (Swagger/OpenAPI).
  • Automated Testing validation.
  • Frontend form generation.
