I was playing around with reading password protected spreadsheets in ColdFusion 21 with cfspreadsheet(), and of course discovered that it can't read them. At least the error message acknowledges the need for the password (which is kind of maddening). More importantly, if you use isSpreadsheetFile() on a password protected excel file, it returns false, which is not true. The spreadsheet is a valid spreadsheet, it just can't be opened by ColdFusion which can already tell that it is a valid file that is password protected. This is a bug, no?
