At least one column must be present.
All columns must be filled to be able to map with useful information.
Having more columns than required is possible.
Only the first row will be read into the importer. It is possible to successfully upload 0 rows of information, as long as all required columns are present, the importer will still “succeed” in mapping the csv file.
Mapping will allow any column to be mapped to any column “header”.
A demo spreadsheet can be found here.
