A batch file could do that (amonsgst other things such as an excel macro). Tr this:
@Echo off
setlocal enabledelayedexpansion
del outfile.csv 2>NUL
REM NETWORK,000123,E,BEP,125.00,$,1
for /f "tokens=1-7 delims=," %%a in ('type RESPNET.csv') do (
set /A id=1%%b - 1000000
if not "%%c%%d%%e"=="" echo echo %%a,!id!,%%c,%%d,%%e,%%f,%%g >> outfile.csv
)
notepad outfile.csv
