Use this JavaScript Prettify tool to format compact or messy JavaScript into a more readable structure. It is useful for debugging copied snippets, inspecting generated code, reviewing minified-looking samples, cleaning simple scripts, and making JavaScript easier to scan before editing or sharing.
