Unable to convert blanks within CSV using NullDisplay

• All Qlik Sense versions

• Nulldisplay does not work with CSV files since these are containing empty strings (not null values)
• The use of Nulldisplay only affects data from an ODBC data source (as documented in the Help).

• Use a Map statement with a mapping load to map these null values into specific strings.

NullMap: 
Mapping load null() as Old, '' as New autogenerate 1; 
Map /CategoryName, Country, Discount, Fax/ * using NullMap; 

set nullinterpret=''; 
//set nulldisplay=''; 

T1: 
LOAD  
CategoryName,  
Country, 
Discount,  
Fax 
FROM ..\gettingstarteddata.csv (txt, codepage is 1252, embedded labels, delimiter is ',', msq);
