Please use Matrix Fieldtype & Inputfield Or the ProFields. FieldtypeJson (module) Álpha I've been busy last 2 weeks with a new fieldtype. I needed a fieldtype that generates JSON strings from CSV (excel data). I needed a way to handle a variable amount of columns & needed a way to manage that data. Wanze & Kongondo already worked on a excel crud module with the excellent Excel-like data grid editor Handsontable and I loved that piece of software. Thank you guys. Handsontable is
