database

We're using oracle EE v19 and I know that with the upcoming v23c we can now extract tabular data in json format, but does that require the database be 23c or can we get the same output with an v23c oracle client (SQL*Plus) connecting to a v19 DB?

Basically we need to extract tabular data using SQL*Plus from a script, where some column(s) are large varchar and might contain formatting including [\n, \t, \,] that would "throw off" a csv format extract.
