How to replace every server script in game with a local script?

It's possible to quickly convert every server script you have to a local script by using the script's Source property, which contains the code within the script.

Simply copy paste this code into your command bar in Studio and it should convert every server script you have (in ServerScriptService) into a local script:

--Please use this code with caution
for _,v in pairs(game.ServerScriptService:GetDescendants()) do -- You can change game.ServerScriptService to wherever else you want to convert your scripts.
	if v:IsA("Script") then -- Checks if instance is a server script.
		local LocalScript = Instance.new("LocalScript")
		LocalScript.Name = v.Name -- Sets local script name to script name.
		LocalScript.Source = v.Source -- Copies server script code into local script.
		LocalScript.Parent = game.StarterGui -- You can change where the local script is parented here.
		v:Destroy() -- Destroys server script. Remove if you don't want to remove your server scripts.
	end
end

Basically this code loops through ServerScriptService and copies every server script's code into a new local script, then parents the local script into StarterGui. Then the server script is destroyed.

If you don't know how to open the command bar, the button to toggle it should be located in View > Command Bar somewhere at the top of your screen. The command bar usually shows up in the bottom of your screen.

Please note this ONLY works in the Studio command bar and plugins. This script will not work in server and local scripts as the Source property is locked for those.

Hope this helped! If you have any questions, just comment!
