Lua Code Formatter

Lua Code Formatter

Paste your Lua code and get a cleanly indented, evenly spaced version in one click. The formatter understands Lua block structure (if/then/end, do/end, function/end, repeat/until) and normalizes operator spacing without sending your code anywhere — everything runs in your browser, so it works for proprietary game scripts, embedded device firmware, and config snippets.

Comment utiliser

1. Paste your Lua source into the input area, or click Essayez un exemple pour charger un exemple.
2. Pick your indent style: 2 spaces (default), 4 spaces, or tabs.
3. Basculer Preserve comments if you want to strip both line and block comments instead of keeping them.
4. Basculer Réduire plusieurs lignes vides to merge runs of empty lines into a single break.
5. Cliquez Format. Use the copy or download icon to grab the result.

Caractéristiques

• Block-aware indentation – Tracks Lua keywords (then, do, repeat, function, end, until, else, elseif) to produce consistent nesting.
• Espace autour des opérateurs – Normalizes spacing around =, ==, ~=, .., arithmetic, and comparison operators while leaving table indexing (t.x) and method calls (obj:m()) tight.
• Sécurité des chaînes et des commentaires – Long strings ([[...]], [=[...]=]) and block comments are preserved verbatim; nothing inside them is reformatted.
• Indent style choice – 2 spaces, 4 spaces, or tabs.
• Comment control – Keep your comments or strip them all.
• Blank-line cleanup – Optional collapse of long stretches of empty lines.
• Privacy by default – 100% client-side, no upload, no AI round-trip.

Who It Is For

Lua shows up in game scripting (Roblox, Love2D, World of Warcraft addons, Garry’s Mod), embedded environments (OpenWrt, Redis modules, Neovim configs), and many CI pipelines. If you write or review Lua often, you want a fast, deterministic formatter that does not need a local toolchain. Drop in a snippet from a forum post, a co-worker’s pull request, or a generated config and clean it up instantly.
