JSON to JSON Schema

The SON to JSON Schema tool is a utility designed to convert SON (Schema Object Notation) into a JSON Schema, which defines the structure and validation rules for JSON data. JSON Schema is widely used for validating API requests/responses, configuration files, and other JSON-based data structures.

This tool automates the process of transforming a human-readable schema format (SON) into a standardized JSON Schema, saving developers time and reducing manual errors.

Key Features

1. Automated Conversion – Quickly translates SON structures into valid JSON Schema (Draft 7 or later).

2. Validation Rules Support – Preserves constraints like required, type, minLength, maxLength, pattern, and more.

3. Nested Object Handling – Accurately converts complex nested SON objects into corresponding JSON Schema definitions.

4. Type Inference – Detects and applies appropriate JSON Schema types (string, number, boolean, array, object).

5. Customizable Output – Allows modifications to the generated schema for specific use cases.

6. CLI & Web Interface – Available as a command-line tool or web-based converter for flexibility.

Why Use SON to JSON Schema?

• Standardization – Ensures compatibility with tools that rely on JSON Schema (e.g., Swagger/OpenAPI, AJV validator).

• Developer Productivity – Eliminates manual schema writing, reducing errors and speeding up development.

• Improved Data Quality – Enforces strict validation rules to maintain data consistency.

• Integration-Friendly – Works seamlessly with API documentation tools and validation libraries.

Example Conversion

Input (SON)

{
  "user": {
    "name": string (required),
    "age": number (min: 18),
    "email": string (pattern: "^[^@]+@[^@]+\\.[^@]+$"),
    "is_active": boolean,
    "roles": string[] (minItems: 1)
  }
}

Output (JSON Schema)

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "user": {
      "type": "object",
      "required": ["name"],
      "properties": {
        "name": { "type": "string" },
        "age": { "type": "number", "minimum": 18 },
        "email": { 
          "type": "string", 
          "pattern": "^[^@]+@[^@]+\\.[^@]+$" 
        },
        "is_active": { "type": "boolean" },
        "roles": {
          "type": "array",
          "items": { "type": "string" },
          "minItems": 1
        }
      }
    }
  }
}

Use Cases

• API Development – Generate JSON Schemas for request/response validation.

• Configuration Management – Ensure structured and validated config files.

• Data Pipelines – Validate JSON data before processing.

• Documentation – Auto-generate schema docs for APIs.

Available Implementations

Several tools and libraries support SON-to-JSON-Schema conversion:

• Online Converters – Web-based tools for quick conversions.

• Node.js Libraries – Programmatic conversion in JavaScript/TypeScript.

• CLI Tools – Command-line utilities for scripting and automation.

Conclusion

The SON to JSON Schema tool bridges the gap between a simple schema definition (SON) and a standardized JSON Schema, making data validation and API development more efficient. By automating schema generation, developers can focus on building robust applications without worrying about manual schema errors.
