I forgot to post this, I made an enhanced example from the great Einhugur JSON III plugin.

it helped me understand about how the plugin works,
Plus, I posted before, I opened a 7 gigabytes json file with it in couple minutes, incredible !
I will add couple more things to test later
I use JSONMBS too, depends on cases, I made an enhanced example too, might post it too.
