In the CSV file, enter the names of the groups, separated by colons (“:”) in the “group” row of the user you wish to let belong to multiple sections, and the user will belong to the groups you entered the names of.
e.g., You wish to enter this user to three groups, namely “Castalia”, “Goocus development group”, and “Test group”.
In the CSV file, enter
Castalia:Goocus development group:Test group
in the “group” row of the user in question.
Import the CSV file, and now the user belongs to:
Goocus development group
Unfilled columns are not used, but they are left for compatibility with the existing CSV file.
