Use the export meeting stats report to generate a list of individual attendance for the group's meetings plus all custom stats recorded for those meetings.
Note: Here, there are two "Attendance" stats; the first is individuals' attendance. The second is a custom attendance stat; it simply is a headcount.
There are two formats you can pick from when exporting a meeting stats: CSV and Web Page Format. CSV will export all the selected stats to a simple spreadsheet that you can use in Microsoft Excel and many other programs. The Web Page format will display all the stats in tabular format, which is handy if you want to print the report quickly.
