I don't have a proper solution for you as of yet, but here's something you can try in the meantime that might help:
Open the CSV file in a text editor and do a search-and-replace of
,,
with
,"",
Thus, you'll change
0001,Title,Description,,Item,,,Item
into
0001,Title,Description,"",Item,"","",Item
...which should work.
You may need to repeat the search-and-replace to catch all the double commas.
Note that if you have any double commas in legitimate strings, such as
0001,Title,"My favourite punctuation characters are the comma,, doublecomma,, and the semi-colon.",,Item,,,Item
...you'll need to manually fix that line because after you do the search-and-replace, you'll have a line that isn't valid CSV:
0001,Title,"My favourite punctuation characters are the comma,"", doublecomma,"", and the semi-colon.","",Item,"","",Item
Hope this helps!
All the best,
Chris
