Live data from a file? That's hardly the definition of live.

Live data from a people counter. The Arduino counts the number of people in a room. I want to send this data live to web page via FTP

I guess, then, that FTP - File Transfer Protocol - means something different to you.

You can't FTP a file to a web page. You can use HTTP to send data in response to a client request. Part of that response can be meta tags to cause the client to re-issue the request periodically.
