how to remove mass enrollments of learners from a course ?

Hello,

We would like to Remove enrollments of a mass learners from a course ,automatically .

we have a list of learners that have been enrolled to a course, and we would like to remove them from the enrollments

what is the best and efficient way to remove the enrollments ? 

(to enroll the mass employees we used a CVS file and Choose “person number list “)

is it possible to use the initiative to remove the enrollments ? i prefer not HDL if possible.

Thanks a lot
