Hi Karthik,

 

[ {"id":1,"countryname":"India","zoneid":"1","countryid":"1","zonename":"South","stateid":"1","zid":"1","statename":"Karnataka"}, {"id":1,"countryname":"India","zoneid":"1","countryid":"1","zonename":"South","stateid":"2","zid":"1","statename":"Karnataka"}, {"id":1,"countryname":"India","zoneid":"1","countryid":"1","zonename":"South","stateid":"3","zid":"1","statename":"Karnataka"}, {"id":1,"countryname":"India","zoneid":"2","countryid":"1","zonename":"East","stateid":"4","zid":"2","statename":"Karnataka"}, {"id":2,"countryname":"UK","zoneid":"3","countryid":"2","zonename":"West","stateid":"5","zid":"3","statename":"Karnataka"}, {"id":3,"countryname":"Australia","zoneid":"3","countryid":"3","zonename":"West","stateid":"6","zid":"3","statename":"Karnataka"}, {"id":3,"countryname":"Australia","zoneid":"4","countryid":"3","zonename":"North","stateid":"7","zid":"4","statename":"Karnataka"}, {"id":4,"countryname":"Sweedan","zoneid":null,"countryid":null,"zonename":null} ]

Did you try a google search?
Show me a plunk with whatever you tried and is not functioning, then there is probably someone who might help you.

I would start off with JSON.parse()

Hi Sander Elias,

Thanks for your reply. I want to convert json data into tree format (like angularjs tree view). The below one is flat model json data. i need hierarchy json data.
