よくある質問

Quick answers.

Which Haskell libraries are supported?

The generator focuses on the `Aeson` library, producing `FromJSON` and `ToJSON` instances compatible with modern Haskell development.

How does it handle nested objects?

Nested JSON objects are converted into separate Haskell data types, with the parent record referencing these types as fields.

Are Haskell naming conventions followed?

Yes. The tool converts snake_case or camelCase JSON keys into valid Haskell record fields, typically prepending the type name to avoid namespace collisions.

Can I use this for complex arrays?

Arrays of objects are mapped to Haskell lists of a specific type, while mixed-type arrays may require manual adjustment into a Sum type or `Value`.
