JavaScript Formatter
Don't let ugly code slow you down. Instantly beautify your JavaScript, fix indentation, and turn minified chaos into readable logic.
Clean Code is Better Code
JavaScript is forgiving. You can write it on one line, omit semicolons, and mix tabs with spaces. But forgiveness is not a virtue when you are trying to debug a critical error at 2 AM.
Our JS Formatter enforces discipline. It parses your code and rebuilds it with consistent rules, making logical structures (loops, if-statements, function blocks) visually apparent.
Why Standards Matter
Programming is communication—not just with the machine, but with other humans (and your future self).
Readability
Proper indentation allows your eye to scan code structure instantly. You can see where a for loop starts and ends without tracing braces manually.
Debugging
Standard formatting highlights syntax errors. If your code won't format correctly, it often means you have a missing bracket or quote somewhere.
De-obfuscation
Reverse engineering or learning from a library? Paste the minified source here to expand it into a readable format.
Code Reviews
90% of code review comments are about style. Use a formatter to fix style automatically so you can focus on logic.
Legacy Code
Inherited a project from 2015 with no indentation? Run it through the formatter to make sense of the mess instantly.
Minified Libraries
Need to verify what a third-party script is doing? Unpack the compressed code to audit it for security or functionality.
Snippet Sharing
Before pasting code into Slack, StackOverflow, or a blog post, format it. People are more likely to help if they can read your request.
Frequently Asked Questions
Does this support TypeScript?
Yes, basic TypeScript syntax is supported since it is a superset of JavaScript. However, very complex TS-specific features might format as standard JS.
What style do you use?
We use a standard style similar to Prettier, favoring clarity. This typically means 2 or 4 spaces for indentation, semicolons, and spaces inside braces.
Will it fix my syntax errors?
No. A formatter changes the appearance of code, not the logic. It cannot add missing variables or fix logic bugs, though it might make them easier to spot.
Backup First
While formatting is generally safe, always keep a backup of your original code before overwriting it.
Local Processing
Your intellectual property is safe. We do not store, analyze, or even see the code you paste into the window.
