I can give you the cheap answer, which is to do a tools|import\export wizard, but I get the impression you have a greater need than that. I can help, but alot depends on the whats and wheres of your file.
The first thing is that GoldMine does not import excel.
What kind of a file do you have, and where do you want things to go?
Importing into contact1 and contact2 is a relative breeze, but you'll need some serious help if you need to put things anywhere else like additional contacts, history, or details. Michael Phipps
