An administrator can upload multiple cohorts from a CSV (comma separated values) formatted text file in Site administration > Users > Cohorts > Upload cohorts. Cohorts can be created in both the system (site-wide) context or in the course category context.
Once a cohort has been created, new users can be added to it from the Upload users page, using an appropriately formatted .CSV file.
Step 4: On the Cohorts page, click on the 'Upload cohort' tab. You can Drag and Drop the .CSV file containing cohorts for bulk upload into the Drag and Drop box or use the file picker to select .csv file from your computer.
