I finally managed to import my data, except for 1 element - a 'Unique I

I finally managed to import my data, except for 1 element - a 'Unique ID' which is a hidden element and simply doesn't show in the excel headings. Any suggestions for a workaround?

Kindly share to us the URL of the form that you need to import data into the Unique ID field so we can give you the corresponding column name on your import file.

A word of caution though, if you'll be submitting data by filling out the actual form, all your imported data for the Unique ID field will not be checked for uniqueness.
