How do I save the state of multiple instances?

Let's say I have 5 sprites that each have their own specific frame, how do I save the info for the 5 sprites and load it?

0 0 0 0 0

\/\/\/\/\/

0 1 1 0 1

(Restart program)

0 1 1 0 1

Store them in an array perhaps:

save:

event

For each sprite

action

push front of array, set x = sprite.asjson

load:

event

for 0 to array.width-1

action

create sprite on 0,0

set sprite from json string array.at(loopindex)

The array can be stored in a local storage if need be.

edit: subevent meant to be actions
