You can get an object keys this way

var obja = [{USER:"bob",  SCORE:2000, TIME:32,    AGE:16, COUNTRY:"US"}, {USER:"jane", SCORE:4000, TIME:35,    AGE:16, COUNTRY:"DE"},{USER:"tim",  SCORE:1000, TIME:30,    AGE:17, COUNTRY:"UK"}, {USER:"mary", SCORE:1500, TIME:31,    AGE:19, COUNTRY:"PL"}];

for(var key  in obja[0]){
