Google Code Formatter

This tool formats source code to Google's style guidelines across multiple programming languages. It is designed for developers, code reviewers, and engineering teams who aim to achieve consistent presentation in PRs, documentation, and published samples. Conceptually it tokenizes and parses input code, then rewrites indentation, line breaks, spacing around operators, and import organization to align with language-specific Google rules, while preserving comments and string literals to maintain semantics. It supports configurable line length and indentation preferences, enabling teams to enforce a uniform look across codebases. The formatter is language-aware and deterministic: the same input always yields the same formatted output, which simplifies diffs and audits. Its value lies in speeding up reviews, reducing stylistic disputes, and ensuring documentation examples remain readable. It is designed to be integrated into CI pipelines or pre-commit hooks for automated formatting, and to provide clean, ready-to-commit code snippets that reflect a shared Google-style baseline.
The tool focuses on formatting rather than semantic analysis; it does not change logic, replace identifiers, or introduce language-specific transformations beyond whitespace and structure. Its cross-language consistency helps teams scale code quality across repositories with minimal manual intervention.
Users range from individual contributors to large engineering teams requiring reproducible formatting standards for code reviews, educational materials, and internal tooling.
