Merging Research Methods: Tips for Integrating User Insights and Observations

I need some support to figure out how best to merge different research types into one project. For my current research incentive, I've interviewed users, have made observations by watching users interact with our product (all of which was noted in a google spreadsheet), and sent out surveys via another platform. Currently I have all the interviews in Dovetail with highlights created, but I'm struggling how best to import the spreadsheet notes so I can use the one column of "observations" as highlights to add to my insights canvas. Any advice?
