Questions fréquentes

Quick answers.

How does inference work?

The tool inspects the data types of your values, such as identifying strings, integers, or arrays. It builds a corresponding `type` definition and maps out the hierarchy of your data.

Can it handle nested objects?

Yes. The generator recursively traverses objects and arrays to create a complete schema including nested `properties` and `items` definitions.

Is the generated schema valid?

The output follows the JSON Schema Draft specification. While it provides a structural foundation, you may need to manually refine specific constraints like `format` or `pattern` for strings.

Is my data safe?

Yes. No data is sent to a server. The conversion logic runs entirely in your browser session for maximum privacy.
