Hi
I have a certificate as a template and I want to add first name and last name to the certificate from excel sheet. I managed to do the mail merge. What I want to do is to show all the certifications in one page. so lets say I have 12 certification then i want to see them all in one page like this

[] [] [] []
[] [] [] []
[] [] [] []

I googled it and someone suggested to execute it to a file. So I tried to print them and the click print to [] File. but could not show them in one word file. How can I do that?
Any idea/video show how to do that? Thank you so much
