Frequently Asked Questions
Does this Lua beautifier support Luau?
Yes. Luau is a Lua dialect used in Roblox. The formatter indents functions, if/then, do/end, and repeat/until blocks the same way, so most Luau snippets format cleanly. Review generated output for unusual macros.
Is this a Lua formatter or a Lua interpreter?
It is a formatter only. Code is never executed. Use it to beautify Lua before review or paste. It will not run scripts or catch runtime errors.
How do I beautify Lua online?
Paste Lua into the input panel. The output indents after function, then, do, and else, and outdents on end, elseif, and until. Copy the result with Copy Output.
Does the Lua formatter upload my code?
No. Beautifying runs in your browser. Nothing is sent to a server.
