Hi Nathan, You can only import Microsoft Project files that are an xml formatted file. That said, there are often little nuances that get most folks. The best option would be to go and download a blank kickstart of the object type you're importing (project in this case) and see what columns are bolded, as those are usually the required columns. If you can get the file to Eric to look at, he's a great resource to use for help, or you can contact our support folks and open a ticket with our Customer Care team, then one of our Tier 1 support reps will take a look at and help out. Best of luck! Dustin Martin Tier 2 Assigned Support Engineer Workfront
