How to convert JSON to array of strings

Is it possible to use for json path to format rows in a JSON array format?

I have a column like this

Col1
====
abc
def
ghi
jkl

and I want to format it like this

{"Col1":["abc","def","ghi","jkl"]}

I have so far gotten it to look like this

{["Col1":"abc","Col1":"def","Col1":"ghi","Col1":"jkl"]}

using this code

select col1 from table for json path
