Haskell possible make own type instance of Text

Question

Noob here again. Getting my feet wet in making my own Haskell 'programs'. Stumbled across this. Made my own type:

data Action = Action 
  { idN         :: IdN
  , description :: Desc 
  , duedate     :: Due 
  , donedate    :: Done 
  } deriving (Ord, Show, Read, Eq) 

Imported Data.Text.IO. Want to write concrete info in Action to file using

TIO.appendFile "./Dbase.txt" typedAction

where typedAction is the concrete representation of the Action type. Now Action is not of type Text. So how would I go about this?
