Tool Calling JSON Schema Generator

Schema Generator converts example JSON data into JSON Schema — a specification for validating structured data. JSON Schema describes the shape of a JSON object: which fields exist, what types they are (string, number, boolean, array, object), which are required, and what constraints apply. It's widely used for API documentation, validation, and — increasingly — for structured outputs in LLM tool-calling architectures with OpenAI and Anthropic.

The generator analyzes example JSON data, inferring the type of each value (string, number, boolean, array, object). It examines array items to determine if they're all the same type (to add `items` constraints) and checks for common patterns like emails or dates. The output is a valid JSON Schema draft-07 document that validates the given data structure.
