Ignore null's in exported .csv file, bcp utility - sql-server

Question

How can I ignore null's in my exported .csv file, I used bcp utility
within sql server, here it is how this looks like altogether.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
IF OBJECT_ID ('[dbo].[generateCSV]') IS NOT NULL
DROP PROCEDURE [dbo].[generateCSV]
GO
CREATE PROCEDURE [dbo].[generateCSV]
(
#table varchar(100),
#output varchar(100),
#date varchar(12),
#server varchar(30)
)
AS
DECLARE #sql varchar(8000)
SELECT #sql = 'bcp "select * from ' + DB_NAME() + '.dbo.' + #table + '
where reportingdate = ''' + #date + '''"' + ' queryout ' + #output + ' -c
-C65001 -t";" -r"\n" -T -S' + #server
exec master..xp_cmdshell #sql
-- Main EXEC
EXEC dbo.generateCSV #table = 'Clients', #date = '2017-10-31', #output =
'//172.18.16.109/share/Test.csv (server with export target location ) ',
#server = '172.18.16.108(server we are connected to and from which we are
taking the data)'
After exporting and opening my file in notepad++ empty columns end up filled with NULL's.
What I want it to look like is...
Edit:
I included ISNULL() in my select clause but still notepad will read those columns as null valued.
SELECT #sql = 'bcp "select
ReportingDate,uniqClientID,registrationNumber,name,ISNULL(vatNumber,'''') as
vatNumber,ISNULL(entityStatusCode,'''') as entityStatusCode,
maximumLifetimeDPD from ' + DB_NAME() + '.dbo.' +
#table + ' where ReportingDate = ''' + #date + '''"' + ' queryout ' +
#output + ' -c -C65001 -t";" -r"\n" -T -S' + #server

SELECT #sql = 'bcp "select * from ' + DB_NAME() + '.dbo.' + #table +
' where reportingdate = ''' + #date + '''"' + ' queryout ' + #output
+ ' -c
-C65001 -t";" -r"\n" -T -S' + #server
Instead of SELECT * write the specific column names.
Wherever you feel NULL can appear you can write like following.
....
SELECT
Column1,
ISNULL(Column2,'') AS Column2,
Column3,
....
from ' + DB_NAME() + '.dbo.' + #table
.....
Note: If you have INT as datatype, you need to slightly change your select according to following query.
DECLARE #INTVAL INT
SET #INTVAL = NULL
SELECT
ISNULL(LTRIM(NULLIF(#INTVAL, 0)), '') AS ColumnName
