Changing the name from object to list.

$Name instanceof Array?$Name :[$Name]

Here name is the attribute which is reffered from csv generator and is converted to list from object.

Output of Mapper
[ { "Name": [ "Harish" ], "age": "26" } ]

Here added an JSON splitter to read the list from the output of mapper.

Below is the output of JSON splitter.
[ { "splitValue": "Harish" } ]
