Datastore, how could I manage, save and load more data without Instance.new() [?]

#Goal:# My Current goal it to save an inventory. The inventory is those that contain an ImageLabel with an image and a Text label to display the quantity of that item.

#Problem:# My problem is that currently when I save things such as "money" I use Instance.new() to hold the value and save/load from that. But say I wanted to make a system where it has a quantity of an item? I don't want to create more Instance.new() and based on how many different items there are there will be a lot of IntValues in a folder. So I want to learn a different way of doing this.

#Script (This is a section):# This is a ServerScript in ServerScriptService

game.Players.PlayerAdded:Connect(function(plr)
	local Stats = Instance.new('Folder')
	Stats.Name = 'Stats'
	Stats.Parent = Player

	local ExampleStat = Instance.new('IntValue')
	ExampleStat.Name = 'ExampleStat'
	ExampleStat.Value = 0
	ExampleStat.Parent = Stats
end)

local function Print(message) -- Ignore my for fun stuff
    if PRINT_OUTPUT then print(message) end
end

local function SaveData(player)
    if player.UserId < 0 then return end
    player:WaitForChild("Stats")
    wait()
    local Stats = {}
    for i, stat in pairs(player.Stats:GetChildren()) do
        table.insert(Stats, {stat.Name, stat.Value})
    end
    leaderboardData:SetAsync(player.UserId, Stats)
	Print('Printing Report From: '..script.Name)
    Print('Report: '..player.Name.." ["..player.UserId.."]".."'s data was Saved!")
end

local function LoadData(player)
    if player.UserId < 0 then return end
	wait()
    player:WaitForChild("Stats")
    wait()
    local leaderboardStats = leaderboardData:GetAsync(player.UserId)
	print(leaderboardStats)
    for i, stat in pairs(leaderboardStats) do
        local currentStat = player.Stats:FindFirstChild(stat[1])
        if not currentStat then return end
        currentStat.Value = stat[2]
    end
	Print('Printing Report From: '..script.Name)
    Print('Report: '..player.Name.." ["..player.UserId.."]".."'s data was Loaded!")
end

players.PlayerAdded:Connect(LoadData)
players.PlayerRemoving:Connect(SaveData)

if SAFE_SAVE then
    game.OnClose = function()
        for i, player in pairs(players:GetChildren()) do
            SaveData(player)
        end
        wait(1)
    end
end

while AUTO_SAVE do
    wait(TIME_BETWEEN_SAVES)
    for i, player in pairs(players:GetChildren()) do
        SaveData(player)
    end
end

Chances are I will have to deal with tables. Basically, I don't want to Instance.new() spam. Or else If a game had 50 items I would need 50 IntValues. and 50 Instance.new()'s

So how could I do this? Can someone please provide a template or an example? Thank you for reading and I appreciate any helpful feedback.
