On this screen, you can select the XLS file to import and assign a Type of participation and Language version common across all registrations added this way.
If there are any agenda events configured in the Agenda tab, you can assign them to all imported registrations, too. Once everything is ready, hit Import.

Prepare the import file

• Make sure the file is a Microsoft Excel 97/2000/XP file. You can tell that by its extension: it should be .xls, as opposed to .xlsx.
• Get rid of the columns you do not want to import. They are obsolete but will increase the file size, which may slow down the import.
• If you want to import data into a select, radio, or checkbox field, use values field1, field2, field3, and so on. They correspond to successive positions in these fields. In the case of a checkbox, if you want to check more than one option, separate the values with commas without spaces, e.g. field1,field3,field4.
