LESS Beautifier: Format and Beautify LESS Code Online
The LESS Beautifier formats LESS code with Prettier’s postcss parser, making stylesheets easier to read and review. You can configure indentation and print width to shape the output. Paste or drop your LESS, choose your options, and copy the formatted result. This tool beautifies LESS; to compile it into CSS, use the LESS to CSS Compiler.
The LESS Beautifier is an online LESS formatter that uses Prettier with the postcss parser. It makes LESS code easier to read and review without turning the stylesheet into CSS. If you need compiled CSS rather than formatted LESS, use the LESS to CSS Compiler.
To format code, paste or drop your LESS into the tool, then set the indentation and print width options. The beautifier applies those settings to the output. If the input does not parse cleanly, it can help you find the exact line to check. Copy the formatted result when you are ready to use it in your project or share it with others.
LESS is a stylesheet language that extends CSS with features such as variables and nesting. Formatting changes the presentation of the source code; compilation is a separate step that produces CSS. A LESS to CSS converter is useful when a project or workflow needs CSS output, while a LESS formatter helps make the original LESS source consistent and reviewable.
The LESS Beautifier runs entirely in your browser. Your input is processed on your device and is not sent to a server, and no signup is required. Once the page has loaded, the tool works offline, so you can format LESS without an active connection.
This browser-based LESS formatter is useful for developers and DevOps engineers who maintain stylesheets, review changes, or need to tidy a code snippet. Whether you are preparing a commit or investigating unfamiliar LESS, configurable indentation and print width help you produce output that is easier to inspect.
Step 1: Paste or drop your LESS into the tool. Start with a complete stylesheet or a smaller code snippet.
Step 2: Choose the indentation and print width options. These settings control how the formatted LESS is laid out.
Step 3: Review the formatted output. If the input does not parse, use the reported line to find where to check your code.
Step 4: Copy the result and use it in your project, code review, or bug report. For CSS output, use the LESS to CSS Compiler.
Use case: Make an unreadable, machine-generated LESS file easier to review before committing it.
Use case: Check a LESS document you did not write against the formatting expectations for your project.
Use case: Produce consistently indented output so a diff highlights code changes instead of whitespace noise.
Use case: Format a LESS snippet before adding it to a bug report or code review.
Use case: Check whether LESS input parses cleanly and use the reported line to locate a problem.
Use case: Prepare a stylesheet for sharing with teammates by choosing indentation and print width that make it easier to read.
