What JavaScript Pretty Print does
The JavaScript Pretty Print tool on CodeBeautify converts raw or minified JavaScript code into a clean, readable format by automatically adding standard indentation and line breaks. Users input their code and receive an instantly formatted version that makes complex scripts easier to review and understand. Beyond basic formatting, the tool includes validation to check if the input is valid JavaScript before prettifying, and supports loading code via URL or uploading a file.
