JSON Schema Studio is a desktop developer toolkit for inferring, validating, and generating mock payloads from JSON Schema Draft-07 and Draft 2020-12 specifications.

Key Features:

• Schema Inference Engine: Infers complete JSON Schema Draft-07 or 2020-12 definitions from single or multiple JSON objects and arrays, computing type, required keys, nested properties, additionalProperties, array items union merges, string format detection (email, uri, uuid, date-time), and numeric min/max or enum inference.
• Strict Batch Validator: Pure-Python recursive JSON Schema validator reporting exact $.path pointer errors (type mismatch, missing required key, pattern, minimum, maximum, enum, format, additionalProperties) across live editor input and batch JSON folders.
• Sample Mock Generator & Exporter: Synthesizes valid sample JSON matching any schema and exports .schema.json files, Markdown API documentation, and batch validation CSV reports.
