The JetEngine Repeater field lets you add content as a set of subfields, such as slides, team members, etc. Any JetEngine field type can be used in these subfields. The repeater field acts as a parent to the subfields.
For example, this Repeater field contains two subfields: a number and a text.
During an export, WP All Export will add a column for each subfield that the repeater field contains. In this example, this JetEngine repeater field would export:
A Repeater_number column that contains all repeated numbers separated by a pipe ( | ) character.
A Repeater_text column that contains all repeated text strings separated by a pipe ( | ) character.
Here's what that JetEngine export file would look like:
