Replace() in SQL isn't working with "

Question

I'm receiving a JSON string into a database which I'm trying to convert into a comma delimited list. This is my current state:

My SQL currently looks like:

BEGIN TRANSACTION

SELECT  Id, 
        PriorityGroups ,
        REPLACE(
            REPLACE(
                REPLACE(PriorityGroups, '["', ''), 
                    '"]', ''), 
                    '"."', ', ') AS 'Updated to comma delimited'
FROM    dbo.CA
WHERE   Id= 51

ROLLBACK TRANSACTION

For whatever reason when I try to replace

"."

With a comma and a space it's not making any changes to the output. I've tried escaping the double quotes but I'm being told it's invalid syntax and I'm not too sure what else to try!

Its not "." to be replaced in string. The characters to be replaced are ","

SELECT  Id, 
        PriorityGroups ,
        REPLACE(
            REPLACE(
                REPLACE(PriorityGroups, '["', ''), 
                    '"]', ''), 
                    '","', ', ') AS 'Updated to comma delimited'
FROM    dbo.CA
WHERE   Id= 51

A valid JSON string is comma delimited and not delimited by period . character
