JavaScript Formatter
Format and beautify JavaScript code with proper indentation and syntax highlighting. Minify JS to reduce file size. Supports ES6+ including arrow functions, async/await, and modules.
How to Format JavaScript
Paste minified or messy JavaScript into the input panel and click Format to beautify it with proper indentation. Choose between 2-space or 4-space tabs. The formatter handles ES6+ syntax including arrow functions, template literals, destructuring, and async/await. Use the Minify button to compress code for production. Need to format JSON instead? Use our JSON Formatter.
Why Format Code?
Properly formatted code is easier to read, debug, and maintain. Consistent indentation reveals the logical structure of nested blocks, callbacks, and conditional chains. Minified JavaScript from build tools or CDNs is nearly impossible to debug without formatting first. Format SQL queries with our SQL Formatter.
Common Use Cases
Beautify minified production code for debugging. Format copied snippets from Stack Overflow or documentation. Clean up auto-generated JavaScript before code review. Minify code to reduce bundle size for deployment. Test patterns in your code with our Regex Tester. All formatting runs in your browser — your code never leaves your device.
