How to Organize Ugly JavaScript Code

Learn how to add neat spaces back into your squished JavaScript files.

If you ever download a JavaScript file from the internet, you might notice that it looks like one giant, never-ending word. This happens because the code was squished to save space.

Squished code is great for computers, but it is a nightmare if a human wants to read it or fix a bug.

You can unsquish the code using our JS Beautifier tool. It is the exact opposite of shrinking the code.

Just paste the ugly code in, and the tool will magically put all the spaces, line breaks, and colors back in the right spots so you can finally read it again.
