About This Tool

This tool provides a web-based, language-aware code formatter that standardizes formatting across multiple programming languages. It processes raw code input and outputs a clean, style-consistent version suitable for review and collaboration. Conceptually, the formatter tokenizes code according to language grammar, applies canonical whitespace, line breaks, and indentation, and then reconstructs the code while preserving identifiers and semantics. Users benefit from a consistent style across a repository, which reduces review time and helps enforce internal guidelines. The system supports per-language presets and custom options, enabling teams to tailor indentation width, line length, quote style, and trailing comma rules. A diff-friendly output option helps reviewers spot changes without digging through lines. The tool is particularly useful before commits or pull requests, in CI pipelines, and when aligning legacy code with newer style guides. Its differentiators include language-specific handling, preservation of comments and string literals, and the ability to auto-detect language when not specified. Use cases include JavaScript/TypeScript standardization, Python PEP8 alignment, JSON pretty-printing, and YAML formatting, all while maintaining readability and consistency across a team's codebase.

How to Use

Provide inputs: paste code, select language, set line length and indentation.
Choose formatting style: canonical, compact, or custom presets.
Run formatting to produce formatted_code.
Review the output and, if needed, adjust presets and re-run.
Copy, download, or paste the formatted code into your project.

Frequently Asked Questions

Find Quick Answers

What languages are supported?
The tool supports a broad set of languages with language-aware formatting rules. If a language is not specified, the formatter will attempt autodetection and apply the most probable style. This yields consistent results across JavaScript, Python, JSON, and many others.
Will formatting alter comments or semantics?
Formatting preserves comments and string literals and does not execute code or alter runtime semantics. The goal is whitespace and style normalization while keeping the original behavior intact.
Can I integrate with IDEs or CI/CD?
The tool is web-based for on-demand formatting and can export formatted code for integration. API or IDE integrations can be planned as follow-ons to automate formatting in pipelines or editors.
What happens with syntax errors?
If syntax errors are detected, formatting proceeds with a best-effort approach and a diagnostic note is returned. Changes are conservative to avoid introducing instability, and users can reattempt after fixes.
