I want to make a form fillable PDF with a working excel spreadsheet. Is that possible? Is there a way to embed an excel sheet into a PDF and have the formulas still make the calculations? I don't want to attach the excel to the PDF as I've seen in other posts. The excel calculates the total of a wine order.
No, it's not. You will need to re-create all the cells from the Excel file as form fields in Acrobat to be able to perform calculations or accept user input.
