Steps to take when converting your Student Organization's Roster from Google Sheet to a CSV file or Microsoft Excel to a CSV file.
The only column needed to upload a roster to the Student Organizations App is a Username column or Email column. All others should be removed before exporting.
Under the Google Sheets File menu, select Download → Comma-separated values (.csv, current sheet).
Under the Microsoft Excel File menu, select Save As...
In the Save As pop up under File Format, select Comma Separated Values (.csv).
