Once you have saved the file as an Excel file on your own hard drive, you can use that file to produce your own reports. You can also use it as a Data file in Microsoft Word or most other word processing programs to produce letters, emails or merge to badges, name tents, etc.
Note that the csv file will be saved on the system for 48 hours only, so if you need the data, please keep a copy on your own system.
