Suggestion to support and/or document empty cells in csv importer

[Former user]

I cannot seem to find out how to properly import csv spreadsheets with empty cells.

Suppose I have two items, Q1 and Q2. I want to set P3=Q3 for the former and P4=Q4 for both items. Hence my csv would look like this:

qid,P3,P4
Q1,Q3,Q4
Q2,,Q4

This would result in the following error message for Q2:

{"type":"unknown","text":""}

I cannot seem to find out how to properly mark the field as deliberately being empty. The documentation does not seem to cover this subject.

I would strongly suggest that the importer tool would just silently skip the transaction for any empty cell.
