Add double quotes " " to text string and replace coma with pipes delimiter in CSV File

See below my Workspace to generate a CSV file from a SQL View:

The CSV looks good except I need to put double quotes (“ “) for certain text strings. For example under Ledger Type column, AA should be ‘AA’.

Please let me know which of the String Function(s) in AttributeManager I should use to put double quotes around text strings (or other Transformer you deem more efficient):

Also, how can I replace all the comma separators in the CSV file with pipes character ’|’ instead.

Many thanks!
