Frequently asked questions
Which languages can it format?
It cleans up and consistently indents common web and data formats such as JavaScript, JSON, HTML, and CSS, turning messy code into something easy to read and review.
Is my source code uploaded to a server?
No — formatting happens entirely in your browser, so your code never leaves your device. That makes it safe to use even with private or proprietary snippets.
Does formatting change what my code does?
No — it only adjusts whitespace, indentation, and layout for readability. Your code’s behaviour stays exactly the same.
Is it free?
Yes — formatting is completely free with no sign-up and no limits.
