The Roblox LUA Script Formatter is a dedicated developer-grade beautification and static syntax analysis utility tailored for Roblox Studio creators. Unlike generic JavaScript or JSON prettifiers that break on Luau-specific syntax such as compound operators (+=, *=) and strict type assertions (plr: Player?), our engine employs a compiled WebAssembly binary of Luau's native tokenizer.
Everything you need to know
Does this tool support Roblox's Luau dialect?
Yes! The parser supports all Luau syntax additions, including type annotations, compound operators, and string interpolations.
Is my code sent to any server?
No, the entire formatting and parsing engine runs client-side in WebAssembly inside your browser. Your proprietary code remains completely private.
Can this tool minify LUA code for production?
Yes, you can toggle between 'Beautify' mode for readability and 'Minify' mode to compress file size for faster execution.
