Are you asking whether you can place the form data into a certain file format (txt, doc, etc.) and include that as an attachment on the e-mail? While that's not impossible, it is rather involved and would require quite a bit of code.
If you simply want to display the form data differently in your e-mail from the way it looks in your form, what you can do is use a toggleable field and conditional formatting to display the format you want just while the e-mail is being sent.
