Why to use Code Beautifier?
Minified code is difficult to read and nearly impossible to debug. It lacks indentation, spacing, and structure. This tool helps restore the original formatting, making it easier to understand logic, fix errors, or learn from existing scripts. You can use the js unminify feature to reformat minified JavaScript, or the html beautify function to reveal the layout structure of a web page. Similarly, css beautify feature lets you inspect stylesheets, and json unminify and xml beautify allow you to work with structured data more clearly. These features make this tool ideal for debugging, code review, reverse engineering, and educational purposes.
