What is a JSON to JSON Schema Generator?

A JSON to JSON Schema generator is a tool that automatically converts your raw JSON data into a valid JSON Schema. JSON Schema is a format used to describe the structure and validation rules of a JSON document. It ensures your data is correctly structured and meets predefined rules.

For example:

• Ensures required fields are present
• Validates data types (string, number, boolean, etc.)
• Defines patterns, lengths, and value constraints
