Is there a work-around that allows missing data to equal NULL for LOAD DATA INFILE in MySQL?

load-data-infile

I have a lot of large csv files with NULL values stored as ,, (i.e., no entry). After a lot of searching I found that this is a known "bug", although it may be a feature for some users. Is there a way that I can fix this on the fly without pre-processing? These data are all numeric, so a zero value is very different from NULL.

Or if I have to do pre-processing, is there one that is most promising for dealing with tens of csv files of 100mb to 1gb? Thanks!
