I got sick of building spreadsheets, then exporting to CSV to use gam for various administrative tasks, so I just rolled my own simple tool.

This has grown to handle pretty much all of the classroom management tasks you'd need at a school level. Building it in a spreadsheet makes it very easy to just use spreadsheet functions to do other data massaging as needed to get what you need from your SIS into google.

Tasks it handles:

• Creating courses
• Adding teachers to courses
• Adding students to courses
• Inviting/Removing guardians
• Listing courses, teachers, students and guardians.
