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!
