Two options are available, to import new users and to update existing user's roles.
Users may be imported by uploading a CSV containing appropriate details. The following columns are available:
The format of the downloaded user CSV is the same as the format for imports.
To make mass changes to users' roles, upload a CSV with the following columns:
Different actions may be mixed in the same upload file. A user may appear more than once in the file, for example to add roles and remove roles in the same run.
For both operations, if there are errors the import/update is completed for u=items with no errors, but a CSV is downloaded to your browser that is a copy of the uploaded file but with a column added called 'Errors' which identifies line not executed and why. You can edit this file and reload directly.
