Use the following page to import event attendees.
Import limit: Event attendee CSV imports are capped at 1,000 data rows per file. If your file contains more than 1,000 attendee rows, the upload is rejected.
If you need to import more than 1,000 attendees, split the CSV into smaller files, keep the header row in each file, and upload each file separately.
The import engine doesn't check for duplicates. If the contact already exists in LeadCenter, a new contact with a different contact ID will be created. You can use the merge feature to merge old and new contacts together.
