About This Tool

The tool provides a language aware code formatter extension that ensures consistent style across a codebase. It serves developers, code teams, and engineering managers who want predictable diffs and faster reviews. It formats code automatically without altering program logic.
Conceptually, formatting is achieved by language specific engines that parse code into tokens and reassemble it with defined rules. The process preserves comments and strings while normalizing indentation, line length, and spacing. It supports per language style files and global profiles.
Core value includes reduced code review time, improved collaboration, and easier onboarding for new contributors. Use cases include prep for PRs, pre commit checks, and CI formatting steps. Advanced features include custom style profiles, per language overrides, and batch formatting of multiple files.
