[Haskell-beginners] capital letter name in record syntax (parsing json)

Hi, please,...is it possible to use a capital letter in record syntax data definition? For example data Car = Car { CarName :: !Text ,CarColor :: !Text } deriving (Show,Generic) When I try this I get: parse error on input `CarName' The thing is that I'm trying to parse a json file (with Aeson package) that has records starting with capital letter. After that I would like to parse the JSON file with following code: d <- (eitherDecode <$> getJSON) :: IO (Either String [Car]) where getJSON gets the json file from url If not, what alternative do I have? thanks, m.
