How to delete data?

Question

I want to remove all data checks from the sheet, tried to follow, but he does not get rid of them. Anyway, to do this through a script application?

var ss = SpreadsheetApp.getActiveSpreadsheet(); var accountSheet = ss.getSheetByName("Account A"); accountSheet.getRange(1,1,274,61).clear(); 

Answer 1

 accountSheet.getRange(1,1,274,61).setDataValidation(null) 

That should do the job.
