And what have you tried?[^]

This is not really "format", just the sample of something.

If you simply define A and B, you could use it in JavaScript immediately:
var A, B
var array = [[A,150,500,6000],[B,160,700,7000],[B,200,633,9000],[B,210,633,9000]]
// now you can access members directly:
var second = array[1]; // returns [B,160,700,7000]
var element = array[1][1]; // returns first number, 140
Alternatively, you can parse string, and so on, but you can simply use it as the argument of the call to eval and do all of the above.
