If you have a Windows computer, there is a way to import a CSV file, using PowerShell command line tools
And there’s also info on Installing PowerShell on a Mac, but it requires several steps and you also have to install MacPorts then openSSL
I followed the instructions and it actually does work - I didn't use it in my actual course, but I successfully added people I know to my “test team”. If you’re comfortable with the command line I’d say it’s definitely worth it - I will probably use this in the future even for 20 students.
One modification to the installation of MacPorts - after installing, before you can run the port command you need to run the following command in a Terminal window:
echo 'export PATH=/opt/local/bin:/opt/local/sbin:$PATH' >> .zshrc
Then open a new Terminal window for it to take effect.
One modifications to the instructions in the first link - in Step 6 the correct command is not just Get-Team but Get-Team -User your_netID@dal.ca (Subbing in your own netID)
