You can always export your submission data to use as part of the judging process or to access all of the data your hackathon has collected. Once projects have been submitted you can export the submission data by going to the metrics section in your hackathon's dashboard.
Note: if your export is empty that may mean you didn't set the visibility of your submissions. Read about moderating submissions here.
Using submission data for judging
Every hackathon runs judging differently, with the most popular method being a science fair style expo. Most in-person events that run judging this way need a way to show hackers, judges and sponsors where each project is located.
Devpost has a built-in feature to auto-assign table numbers and share them with your hackers, judges and sponsors. Read more about assigning table numbers through Devpost.
