The standard Age Calculation workbooks with the extension *.AGE cannot be opened in Microsoft Excel 2000-XP-2003 without running ArArCALC. These files are password protected to circumvent the possibility of (unexpected) changes made to the workbooks, leaving these files unreadable by ArArCALC itself. However, if you save your calculations via the File # Save as Editable Excel File (Ctrl+E) option, the password protection and the Microsoft Excel macros are removed. Now you can open these newly-saved files with the extension *.XLS in Microsoft Excel and change the format of their data tables and diagrams manually. A progress bar appears, showing you the status while saving these editable files.
