Lua Beautifier: Format and Clean Up Lua Code Online
Lua Beautifier formats Lua code with StyLua compiled to WebAssembly, helping make source easier to read and review. Paste Lua, then configure indentation, column width, and quote style before copying the formatted result. The tool runs in your browser, so your code is processed on your device rather than sent to a server. After the page loads, it also works offline.
Lua Beautifier is a browser-based Lua formatter that uses StyLua compiled to WebAssembly. It helps you make Lua source code easier to read, review, and share, with configurable indentation, column width, and quote style.
Paste or drop in Lua code, select the formatting options, and copy the formatted output. StyLua applies a consistent style to the code; the available controls let you adjust indentation, the preferred line width, and quote style. If input does not parse cleanly, the tool can help you find the line where the issue occurs.
Lua is a programming language, and formatting changes how its source code is laid out without changing the purpose of the code. Consistent formatting makes long or machine-generated files more approachable and helps code reviews focus on meaningful changes rather than inconsistent whitespace. Use the formatter when you want a uniform presentation before committing code, comparing files, or sharing a snippet.
Lua Beautifier runs entirely in your browser, and your input is processed on your device rather than sent to a server. Once the page has loaded, it works without a connection, so you can format code offline. It is useful for developers and DevOps engineers who want a quick way to format Lua, whether they are reviewing a file they did not write or preparing a small excerpt for others.
Step 1: Paste or drop your Lua code into the input area. The tool accepts Lua input for formatting.
Step 2: Choose the indentation, column width, and quote style you want. These options control the formatting of the result.
Step 3: Run the formatter to produce a cleaned-up version of your Lua code.
Step 4: Review the formatted output. If the input does not parse cleanly, use the reported line to locate the issue.
Step 5: Copy the result for your editor, code review, commit, or bug report.
Use case: Make an unreadable, machine-generated Lua file easier to review before you commit it.
Use case: Check Lua code you did not write against the formatting requirements you need to follow.
Use case: Create consistently indented output so diffs highlight code changes instead of whitespace noise.
Use case: Format a snippet before adding it to a bug report or code review.
Use case: Check whether Lua input parses cleanly and locate the line where formatting fails.
Use case: Standardize Lua snippets from different sources before comparing or discussing them with your team.
