Questions
Does formatting change what the code does?
No. Only spaces and line breaks change, so the code behaves exactly as before.
Are my files uploaded?
No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
