Using Flow to Grab Lines of Text Area Into Individual Variables

In a custom object, I have a Text Area(255) field in which a user can input stock numbers, one per line. What I would like to do with a flow is take those lines and assign them into individual variables with the purpose of iterating through each of those stock numbers assigning them to a campaign specified earlier in the object. The flow will be an auto-flow kicked off by a Process Builder process. I know how to accomplish everything except pulling the lines of the text area into individual variables. I would like to avoid any Apex code if possible, as our org is getting fairly close to the limit there. Thank you in advance for any help!

Hi Brad,

I suggest Apex trigger to perform the above operation
 
List<String> lstStockNumber = stockNumberField__c..split('\n')

You can use this apex code in Process builder as well in Execute Apex section.

Thanks
