Hello,
It's a matter of a few hours to add the necessary formulas into your sheet and the fields needed to mail merge the Excel sheet with the Word document. If you prefer, I can add a macro so that to send the email messages directly from the Excel sheet.
A few words about me: I'm developing VBA programs for more than 15 years and I'm a trainer for Excel and VBA for 12+ years. As you can guess, I have done a plethora of similar projects, as well as much more difficult, for both training purposes and business.
Looking forward to hear from you,
Kind regards,
chriskerpini
