Frequently Asked Questions
Will the schema exactly match my data?
The inferred schema is based on the types and structure of the provided sample. It sets all observed properties as required by default and does not add arbitrary constraints (like enum or minLength).
What if my root value is an array or a primitive?
The tool still generates a valid schema with the correct root type – for example 'array' with inferred items, 'string', or 'number'.
Can I relax the strictness (additional properties, required fields)?
Yes, a settings panel lets you allow additional properties and make all fields optional, giving you control over the generated schema.
