I have a webform set up in Drupal 7.64 website into which users can register with their details for an exam. The webform uses a name field, which provides separate fields for First Name and Last Name. I need to import a large number of registrations for this form using CSV files from different institutions. Now, the Webform Import module allows me to download a "template" as a starter file for the CSV, with either Field Names or Field Codes in the header row. Neither format gives me the separate fields for inserting the names into, just a single column for 'Name'. Upon import, all goes fine, except that the name field does not get populated with the CSV data, because the separate fields are not available. How do I get this to work?
