As you're using SQL Server 2016 and ordinal position doesn't matter, have a look at STRING_SPLIT() (Transact-SQL). Then, have a look at how to create a delimited string using T-SQL; there are literally 1,000's of answer out there if you use Google. Post what you've tried if you get stuck, and we'll be happy to nudge you in the right direction.

Ideally, however, don't store your values as a delimited string in SQL Server; store each item in it's own row.
