Beautify JavaScript by re-indenting minified or single-line code into a readable structure. When you are staring at a bundled or minified script trying to understand what it does, consistent indentation makes an enormous difference. This formatter reformats based on braces, brackets and statement boundaries, adding newlines and indentation for blocks while being careful not to break strings, template literals or comments. It is a lightweight structural beautifier meant for reading and quick edits rather than a full linter. Paste your JavaScript, click format, and copy the cleaned-up version. All processing happens in your browser, so proprietary or third-party code you are inspecting is never uploaded to any server.
