Frequently Asked Questions

JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It defines the structure, data types, and constraints for your JSON data, making it easier to validate and document APIs.
Paste your JSON data into the input field, choose your formatting preferences, and click 'Generate Schema'. The tool will automatically create a JSON Schema that describes your data structure.
Type inference automatically detects the data types in your JSON (string, number, boolean, object, array, null) and creates appropriate schema definitions for each field.
When enabled, all fields in your JSON will be marked as required in the schema. When disabled, all fields are optional, giving you more flexibility in validation.
Draft-07 is a version of the JSON Schema specification. It's widely supported and includes features like if/then/else conditionals, readOnly/writeOnly properties, and more robust validation keywords.
Yes, all schema generation happens locally in your browser. Your JSON data is never sent to any server, ensuring complete privacy and security.
