Luau Formatter
Format and beautify Luau code for Roblox with type annotations and full syntax support
Luau Formatting Tips
- Use tabs for indentation, as recommended by the official Roblox Lua Style Guide that StyLua follows.
- Annotate function signatures with Luau types — the formatter keeps them aligned and readable.
- Prefer compound assignments (+=, -=, ..=) and string interpolation (`hello {name}`) for cleaner Luau code.
- Working with plain Lua (5.1-5.4) instead? Our Lua Formatter handles standard Lua scripts. Lua Formatter →
