  The problem with searching for ,, and replacing them with ,'', is that
blank number cells are also quoted. SQL does not like that. :-)

Perhaps in Calc add an unusual combination of characters in thse empty

  The first thing I did was save the freshly-opened .csv as .ods. I get
client data as exports from their Excel spreadsheets (sigh) which I save as
.ods, then clean up. When I save the .ods file as .csv the text fields --
even the blank ones -- are quoted. That's not working with these files.

  I'm trying (with C-h) to replace all blank cells with NA. However, with
105000 rows and about 50 columns it takes a very long time ... I gave up for
today. But, I'll try again tomorrow. Then I can block number columns and
replace the NA with blanks.

Quite the hassle,
