Get control's data in excelsheet without using database

Question

I want to fetch data in excel sheet directly from controls, i don't want to save data in database then use gridview.

Example - i have create a form and in that form i hace created a field like-

name - textbox

so after inserting name in this textbox when i click on submit button, without saving it in database it should generate a excel sheet with name field.

I want some suggestions please.
