If you have created an event and would now like to share it with a group of attendees, there are several ways to do this. You can use and share the public link that is automatically generated for your event. Alternatively, you can invite a restricted group of attendees by email and personal access code. You can find detailed instructions on how to do this in this article.
To invite attendees to your event, use the public link that is automatically generated for your event. Click Events in the left main menu, select your event from the list, and then click Invite Attendees. For detailed instructions on inviting attendees, see this article.
Importing attendee lists via CSV
Instead of entering attendees one by one, you can upload a CSV file. The fields you can import correspond to the registration fields you configure for your event under Registration → Available fields. Any fields that are not included in that list are silently ignored during import.
Supported columns
The following column names are recognized regardless of casing, spaces, dashes, or underscores (so "First Name", "first-name", "FIRSTNAME" all work):
| CSV header | Maps to | Notes |
|---|---|---|
| Mandatory. Used to detect duplicates | ||
| firstname | First name | |
| lastname (or name) | Last name | "name" is accepted as an alias |
| company | Company | |
| title | Salutation | Select field — values are defined in your event configuration |
| display_name | Display name | |
| attendance | Attendance | Select field — values are defined in your event configuration |
| role | Role | Select field — values are defined in your event configuration |
| department | Department | |
| language | Attendee language | Must match one of your event's configured languages, otherwise the event's main language is used |
The exact accepted values for select-type fields (Salutation, Attendance, Role) depend on how your registration fields are set up. Use the same values shown in the registration form.
Three example variants
1. Minimal — just email addresses (no header)
2lw18aus@example.com
fwqwtdr6@example.com
efhfaarb@example.com
Use this format when only email addresses are available. Note: the headerless variant only works if each row contains exactly one email address. If you want to include names or other fields, you need a header row.
2. Excel export with header
email;lastname
anna.schmidt@example.com;Schmidt
peter.becker@example.com;Becker
lisa.mueller@example.com;Müller
A typical Excel export with a header row. Any subset of the supported columns can be used, and their order does not matter.
3. Full dataset with all fields
email;firstname;lastname;company;title;display_name;attendance;role;department;language
anna.schmidt@example.com;Anna;Schmidt;Acme GmbH;ms;Anna S.;live;journalist;Marketing;de
peter.becker@example.com;Peter;Becker;Beta AG;mr;Peter B.;live;employee;Sales;en
This example includes every field recognized by the import.
Format details
- Separator: Both semicolon ";" and comma "," are supported. SlideSync automatically detects which separator your file uses.
- Encoding: UTF-8 (Excel tip: When saving from Excel, choose "CSV UTF-8 (Comma delimited)" to preserve special characters).
- Unknown columns: These are silently skipped. No error or warning is shown. Double-check your header spelling if a field does not appear after import.
- Select-field values: These must exactly match the values configured in your event's registration fields. Use the same values shown in the registration form.
What happens after upload
- New email addresses create new attendees with the values from the row.
- Existing email addresses are recognized. The attendee record is retained, and only the language is updated if it has changed. Other field values are not overwritten.
- Invalid emails are skipped and counted in the result message.
- No invitation emails are sent automatically. If you want to send invitations, use the single-attendee invite form.
