How to Use JSON Schema Generator

1. 1

   Provide example JSON

   Paste one or more representative JSON objects. The tool analyzes the structure and infers types. Include examples showing all possible property types you want to allow.

2. 2

   Review generated schema

   The tool generates a JSON Schema (Draft 7 or later). Check that all properties are present, types are correct (string, number, boolean, object, array), and array items are properly typed.

3. 3

   Add constraints and validation

   Manually edit the schema to add minLength, maxLength, pattern (regex), enum values, minimum, maximum, required fields, and description fields for documentation.

4. 4

   Validate against your data

   Use the schema with a validator library (e.g., Ajv in Node.js) to validate incoming data. Test with both valid and invalid examples to ensure the schema catches errors correctly.
