Understanding Lua Formatting
What is Lua Formatting?
Lua formatting is the process of restructuring Lua scripting files (.lua) with consistent indentation, proper spacing around operators, organized sections, and clean line breaks — while preserving all data and semantics.Lua is widely used for game development (Roblox, Love2D), embedded systems, plugin scripting, and application automation. Our free Lua formatter online tool handles this instantly in your browser. Whether you need to format Lua for game scripts, embedded scripting, configuration scripts, and automation workflows, our tool does it accurately and privately.

What Gets Formatted
- Consistent Spacing: Normalizes whitespace around operators like
=for a clean, uniform appearance throughout the file. - Section Organization: Ensures proper blank lines between sections and table headers for better visual separation and readability.
- Comment Preservation: All comments are preserved exactly as written. Formatting never removes or modifies your annotations and documentation.
- Trailing Whitespace Removal: Removes unnecessary trailing whitespace from all lines while maintaining blank lines for structure.
