C/C++ formatter FAQs
Does this tool validate C or C++ syntax?
No. This tool is focused on formatting and beautifying code. Full syntax validation needs a proper compiler or server-side parser and may be added later.
Is my code uploaded to a server?
No. Formatting runs in your browser, so your pasted or uploaded source code stays on your device.
