What is JSON to Haskell?
This tool transforms JSON into clean, idiomatic Haskell code. It generates data types with `FromJSON` and `ToJSON` instances, making it easy to work with JSON in Haskell.
Why use JSON to Haskell?
Haskell is a strongly typed language where JSON mapping is explicit. This tool automates the process, ensuring your Haskell models are perfectly aligned with your JSON data.
How to use JSON to Haskell
Paste your JSON to generate Haskell data types with `Aeson` instances. It handles nested objects by creating multiple data types.
Example Output
data User = User
{ id :: Int
, name :: String
, email :: String
, isActive :: Bool
} deriving (Show, Generic)
