I'm trying to get datastore to save a table of values but it only saves one?

Hi, I'm trying to create a for loop that gets variables inside the players folder but every time I try I get and error or I only get one. For what I'm doing I can't use json it needs to be a global variable because I need to be able to script adding new values.

game.Players.PlayerRemoving:Connect(function(player)--player leaving the game
    local save = {}--the table of data

    for _, Child in pairs(player.chars:GetChildren()) do --gets the children of the chars folder
        table.insert(save, Child.Value) --should insert the children in but it only inserts one
    end

    dataStore:SetAsync(player.UserId, save)--saves the table 
end)
