my json data looks like this

Code:
[{"page":1,"pages":1,"per_page":"4000","total":240},[{"id":"ABW","iso2Code":"AW","name":"Aruba","region":{"id":"LCN","value":"Latin America & Caribbean (all income levels)"},"adminregion":{"id":"","value":""},"incomeLevel":{"id":"NOC","value":"High income: nonOECD"},"lendingType":{"id":"NC","value":"Not classified"},"capitalCity":"Oranjestad","longitude":"-70.0167","latitude":"12.5167"},{"id":"CDW", "iso2Code":"CH", .......}, {"id":"HGW", "iso2Code":"HD", .......}, ......... {"id": "WFE", "iso2Code":"FW"....}]]
I want to extract this part from above one.

Code:
[{"id":"ABW","iso2Code":"AW","name":"Aruba","region":{"id":"LCN","value":"Latin America & Caribbean (all income levels)"},"adminregion":{"id":"","value":""},"incomeLevel":{"id":"NOC","value":"High income: nonOECD"},"lendingType":{"id":"NC","value":"Not classified"},"capitalCity":"Oranjestad","longitude":"-70.0167","latitude":"12.5167"},{"id":"CDW", "iso2Code":"CH", .......}, {"id":"HGW", "iso2Code":"HD", .......}, ......... {"id": "WFE", "iso2Code":"FW"....}]
How can I read this data using JsonStore? As you can see, in the json format, there is no root key. so I can't define root key to read all the second array data. Is it possible to modify this json data to insert hash key into the original format before reader do their job?
