Frequently Asked Questions
Which programming languages does the formatter support?
The formatter supports HTML, CSS, JavaScript, TypeScript, JSON, SQL, XML, and Markdown. Simply paste your code and select the language from the dropdown.
Can I configure the indentation style?
Yes. You can choose between 2-space, 4-space, or tab indentation to match your project's coding style guide.
Does it work with minified code?
Absolutely. Paste minified JavaScript or CSS and the formatter will expand it into properly indented, readable code — perfect for debugging third-party scripts.
Is it safe to paste sensitive code here?
Yes. The formatter runs entirely in your browser. Your code is never transmitted to any server.
Can I use this instead of Prettier?
For quick formatting of individual files without a local setup, yes. For team projects, we recommend Prettier with a shared config. Our tool is best for one-off formatting tasks.
