Hello, not sure what you want. 

But i think you looking for the Array.prototype.map()-function.

You can iterate over an array and create a new one like:

var array= [[1,2,3],[4,5,6]];
   var jsonObject = array.map(function(value,index,arr){
       var generateNewJson = {
           "first":value[0],
           "second":value[1],
           "third":value[2]
       };
       return generateNewJson;
   });
   
   //jsonObject contains now:
   //[{first:1,second:2,third:3},{first:4,second:5,third:6}]

More information about how to use the map-function you can get here:

Hope that helps you.

Thanks a lot for your answer ;)
