Cassandra stored JSON array parsing in tableau

I am working with tableau and need to parse JSON array which has stored in Apache Cassandra. I could able make connect tableau with Cassandra through spark as described here. I have succeeded to parse JSON object by using jsonpath, but I don't get a solution to parse JSON array.

Please see the sample structure of my data

[{ "name": "Obama" },{ "name": "Barak" }]

Any suggestion please, thanks in advance.
