How do I add a form in an Excel sheet?
How can I add an input form in an Excel sheet. I want to insert values into an Excel cell using the form.
ALT+F11 starts the VBA editor in Excel. In there you can create UserForms (Insert | UserForm) which you can bind into their own modules or attach to worksheets.
I suggest you look at the Excel help or MSDN for details of what you can do with UserForms. There are also a lot of VBA tutorials on the web for exactly this sort of thing. Google is your friend.
