How to spawn objects from CSV file

Hello,

I have been trying to work out a code for awhile now that reads a CSV file, parses the data, and then plots objects based on that data (x,z). Although I am able to parse the CSV file and print the array, I am not understanding how to instantiate objects based on this data.

I have hit a roadblock and really not sure what to do at this point. Does anyone have any suggestions please? Thank you

 var csvFile : TextAsset;
 var prefab : GameObject;
 
 
 var x = new Array();
 var y = new Array();
 var z = new Array();
 var count = new Array();
 var id = new Array();
 
 var j = 0;
 
 function Start(){
     Longitude();
     print();
 }
 
 function Longitude () {
 
     var stringArray = csvFile.text.Replace("\n"[0],","[0]).Split(","[0]);
     
     for(var i = 3; i < stringArray.length; i+=1){
 
 
         switch (i%3)
         {
             case 0:
                 x[j] = stringArray[i];
                 break;
             case 1:
                 y[j] = stringArray[i];
 
                 break;
             case 2:
                 z[j] = stringArray[i];
                 j = j + 1;
                 break;
         }
     }
 }
 
 // Test to see if the array in longitude can be accessed from without. Eventually this code needs to spawn the prefabs
 function print(){
 
     
     for(var t = 0; t < x.length; t+=1)
     
     {
         
         var block = Instantiate(prefab);
         block.transform.position = new Vector3(0+t, 0, 0+t);
         print("The coordinates for line " + x[t] + " are " + z[t] + "." + " Height = " + y[t]);
     }
 }
