How Would I Re-Assemble This Script To Save And Change Values In Tables?

So, I've created a table using HTTP Service and JSON:Encode and JSON:Decode.

I can't figure out how to save this table and change the values inside of it?

ServerScript inside ServerScriptService:

game.Players.PlayerAdded:Connect(function(player)
	local swordData = Instance.new("Folder",player)
	swordData.Name = "SwordData"
	
	local ns = Instance.new("BoolValue",swordData)
	ns.Name = "NS"
	
	
	local http = game:GetService("HttpService")
	
	local items =
	{
		Swords = 
		{
		["Normal Sword"] = true,
		["Cool Sword"] = false
		}
	}	
	
	wait()
	
	local savedTable = http:JSONEncode(items)
	
	print(savedTable)
	
	local loadedTable = http:JSONDecode(savedTable)
	
	print(loadedTable.Swords["Normal Sword"])
	
	player.SwordData.NS.Value = loadedTable.Swords["Normal Sword"]
end)

Any help would be appreciated!
