I’ve been trying to help a friend code a simulator, trying to save a table of data to datastore, yet I have forgotten how to do so, the error and code is below.



local DataStoreService = game:GetService("DataStoreService")


local function leaderboardSetup(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local Coins = Instance.new("NumberValue")
	Coins.Name = "Coins"
	Coins.Value = 0
	Coins.Parent = leaderstats
	
	local Rebirths = Instance.new("NumberValue")
	Rebirths.Name = "Rebirths"
	Rebirths.Value = 0
	Rebirths.Parent = leaderstats
end

------------

local function dataSaver(player)
	local dataTable = { 
		
	}
	for _,value in player:WaitForChild("leaderstats"):GetChildren() do
		dataTable[value.Name] = value.Value
	end
	
	print(dataTable)
	local data = DataStoreService:GetDataStore("PlayerData")
	data:SetAsync(player.UserId.."_Stats", dataTable)
end


game.Players.PlayerRemoving:Connect(dataSaver)
game.Players.PlayerAdded:Connect(leaderboardSetup)

ERROR:

Unable to cast to Array  -  Server - leaderstats:32

This is because you need to use some type of dictionary, you should also use pcall functions to make sure the function is “protected”

Try out this script

local DataStoreService = game:GetService("DataStoreService")

local function leaderboardSetup(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local Coins = Instance.new("NumberValue")
	Coins.Name = "Coins"
	Coins.Value = 0
	Coins.Parent = leaderstats

	local Rebirths = Instance.new("NumberValue")
	Rebirths.Name = "Rebirths"
	Rebirths.Value = 0
	Rebirths.Parent = leaderstats
end

local function dataSaver(player)
	local dataStore = DataStoreService:GetDataStore("PlayerData")
	local leaderstats = player:FindFirstChild("leaderstats")

	if leaderstats then
		local dataTable = {}

		for _, value in ipairs(leaderstats:GetChildren()) do
			if value:IsA("NumberValue") then
				dataTable[value.Name] = value.Value
			end
		end

		local success, error = pcall(function()
			dataStore:SetAsync(player.UserId.."_Stats", dataTable)
		end)

		if success then
			print("Player data saved successfully.")
		else
			warn("Error saving player data:", error)
		end
	end
end

game.Players.PlayerRemoving:Connect(dataSaver)
game.Players.PlayerAdded:Connect(leaderboardSetup)
