I have a CVS file with thousands of lines and columns. I need to focus on column AM named or any column named  "EA-domain_list" in that row, I have several domains that are separated by commas in there.

Is there a way via perl, or some type of script that will feed this spreadsheet named master.csv in and take all the EA-domain_list that are in commas, and make new columns for each domain. Basically for example in summary

you look in the attached spreadsheet and look an AM you see mobi.sark.net, ne.sark.net,sark123.test.com I need what ever is in there to strip each domain into a new column like AS would be called EA-domain_list an in there would have ne.sark.net, the another one row AT would have sark123.test.com. Keep in mind some times there are 20 of  then in there. So then I would like to spit out a new file called adjusted_domain_list.csv

Also, I am sorry I didn't mention previously that I am using a Macbook
