How this Python Beautifier works

This code beautifier reformats Python source code with proper indentation and structure. The algorithm analyzes each line for keywords that affect indentation level (def, class, if, for, while, try, etc.) and applies appropriate spacing.

The formatter preserves comments and docstrings while restructuring the surrounding code. Users can choose between 2-space and 4-space indentation to match project standards.

Processing uses JavaScript pattern matching rather than a full Python parser, making it suitable for quick formatting tasks without requiring a Python runtime. All processing runs entirely in your browser.
