I recently completed making a page in HTML & JavaScript.
It is basically a template including various textfields, radio buttons, and dropboxes.
There is also a submit button at the bottom.
My goal is to have a user enter all the input information and then click "Submit."
After hitting submit, I want all of this input information to be sent to Excel.
Unfortunately, I do not know how to do this.
Any advice?

You can't realize how helpful this is. Thank you Daiva. I will uprate you when I am on a different computer that allows me to use a good browser so that I can actually SEE the uprate button LOL! :P
If anybody else has anything they could possibly contribute, I would be most grateful.
Thank you.
