Add single quotes in comma separated string

Hello,

I have a scenario where the location name will come in 2 different scenarios from an API as mentioned below.

1. LOC1
2. LOC1, LOC2, LOC3

The expected output should be

1. ‘LOC1’
2. ‘LOC1’, ‘LOC2’, ‘LOC3’

I tried using the split and replace function but in vain. Appreciate any help provided here

Thanks
