What are the steps to save an excel spreadsheet to the internet so others can view

I have an excel spreadsheet on my C: drive that I want to save on the internet for others to view. When I save it, it always gets saved to my C:drive.

My question: how do I save it so the file name is preceded by http (as other web pages are). Can someone please set out the specific steps I am to take as I am so totally not literate in this area. Someone already asked me if I have a web page - I do not. I also tried saving the file as a PDF but it still gets saved to my C: drive.

I saved it as a "Web page" but only I can view it (my MFP friends cannot connect via the link I sent to their MFP profile page (like a Facebook page).

Thank you.
