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 SAVED IN THE FORMAT OF: CSV UTF-8
Use “CSV UTF-8 (Comma delimited) (*.csv)” — it’s clean, modern, and works well across platforms.
DO NOT USE
❌ CSV (Comma delimited): The BOM (encoding breadcrumb) causes issues.
❌ CSV (Macintosh): Often problematic in modern systems.
❌ CSV (MS-DOS): Doesn’t support special or non-ASCII characters well.
✅ At minimum, you need these two columns:
Email Address: Required for attendee communication and mobile app access.
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.).
Recommended Fields:
Company – Useful for badge printing.
City and State – Optional but may help in organizing attendee details.
Registration Level – Helps categorize attendees for event activities.
Badge Type – Typically includes options like “Exhibitor” or “Default.”
Conference Type – If applicable to your event.

Log into Expo Pass and open your event.
In the menu, click Attendees, then select Upload Attendee CSV
