• EncodeJSON()
• DecodeJSON()

Example

How to save complex statistics to a player:

local Utils = assert(LoadLibrary("RbxUtility"))	-- The library we need
local character_stats = {	-- Some epic stats.
	money = 123456;
	title = "1337 h4x04";
	is_epic = true;
	awards = {
		kills10 = true;
		died20 = false;
	};
}

local JSON = Utils.EncodeJSON(character_stats)	-- Convert the table to a string
local player = game.Players:FindFirstChild("Telamon")	-- Find someone to save the stats to

if player then
	player:WaitForDataReady()	-- Make sure it's safe to save first	
	player:SaveString("Stats", JSON)	-- Save the stats
end
