In the Creator App we have created a form for requesting test products. When this form is completed and submitted zoho creator generates an email with a .pdf copy of that filled out form and starts a workflow. Is there a way to change that auto generated pdf copy to .xls format? I am trying to have that auto-populate an excel document that we track all information on. I see that those pdfs might be a one time, not stored anywhere form. Are they really not stored anywhere?
