About JSON Schema Generator
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. This tool analyzes your JSON data and automatically generates a JSON Schema that describes its structure, types, and constraints. It supports JSON Schema Draft 7 and Draft 2020-12, with smart detection of string formats like email, URL, date, and UUID.
How to Use
Paste your JSON into the input panel. The schema is generated automatically. Adjust options like marking all fields as required, adding titles, or enabling additional properties. Switch between Draft 7 and Draft 2020-12 formats. Use Validate mode to check if a JSON document matches a given schema. Copy the generated schema for use in your projects.
