Code Beautification & Indentation Mechanics
The formatter tokenizes your source code into keywords, operators, strings, comments, and blocks. It normalizes indentation depth, enforces consistent spacing around operators, aligns nested braces and brackets, and wraps long expressions to conform with standard language style guides. This eliminates formatting inconsistencies, simplifies team pull requests, and highlights syntax errors before execution.
