Question

Hello, I'm spitting out data from Access into Excel that has multiple records with the same Primary Key (company name) some of these companies have multiple members. I'm trying to do a mail merge with a PDF document and I need the names all on the same row, each name has multiple columns associated with it ie: shares, address.

Is there a way to combine the rows if the primary key is the same with this program?
