Split file on import

hi, i am trying to migrate my xls notes to DT pro. I have a large xls/csv file with one note per line. If I understand the DT architecture correctly, i need to split the file per line on import, so that DT can start working with each note separately. Is this correct and how do i do it?
Many thanks

You don’t have to, DEVONthink is able to display .xls files and DEVONthink Pro is able to import (and edit) .csv files.
