I'm a teacher, and I use Excel to record student grades for my courses. Each row corresponds to a single student, and each column is the grade for a single assignment.
I would like to share the sheet with my students in such a way that each student is only able to view their own row. Ideally, this would be accomplished with a single sheet, so that I could a mass email with a single attachment. Less ideal, but still acceptable, would be a quick way to break up the single sheet by row into separate files, one per student. I would be receptive to any other creative ideas to efficiently accomplish this task (e.g., using something other than Excel).
