If you've managed registration outside of Expo Pass, you’ll need to import your attendee list by uploading a CSV file. Here’s exactly how to do it!
Before You Start
✅ Make sure your file is a CSV UTF-8 format.
✅ At minimum, you need these two columns:
First Name
Last Name
✅ Prepare any custom fields in advance if you need to upload information beyond the standard Expo Pass attendee fields (like T-shirt size, meal preferences, etc.).
Steps to Upload Your Attendees
1. Navigate to the Attendees Section
Log into Expo Pass and open your event.
In the menu, click Attendees, then select Upload Attendee CSV
2. Prepare Your CSV File
Ensure you have separate columns for each data field.
First Name and Last Name are required.
If you have custom data points outside of the Expo Pass Standard fields that you need to upload, you will first need to do one of the following:
If you are not using Expo Pass for registration, Create Your Custom Attendee Fields.

❗ Important: When saving your CSV file, use the CSV UTF-8 file format. This format will help support special characters in your data upload.
❗ Important: If you plan to allow editing attendee information during Check-In or Onsite Registration, you must include an Email Address column in your upload.
No Email Address? Use a dummy email like name@expopass.io
3. Upload and Map Your Data
Drag your file into the upload area.
Match each column from your CSV to the correct Expo Pass attendee field.
Click Save.
If there are any errors, you’ll be prompted to fix them before the upload can be completed.
