Convert Excel file into interactive website

We have an excel file that we use to place orders with our supplier. It is complex and unnecessarily time consuming. We want the system to ask a series of questions to make the process simpler. We then want the system to email resulting information in three different files in excel format. It is vital that the format of the order file is kept EXACTLY the same. Due to the excessive number of blind bids being placed on this site, we must ask that your bid starts with the first word in the txt file in the attached zip file. Without this, your bid will NOT be considered. If the zip file does not appear, please be patient as it needs to be scanned by freelancer for compliance purposes.
