You may use a powerful command line tool, Microsoft
Log Parser 2.2[
^], to transform CSV and other files to a desired file.
Also you may try the
gwebcmd[
^] command line tool.
It allows you to transform different csv formats into several unified formats for futher import into databases.
For example, to change the separator, run:
gwebcmd texttocsv src.csv dest.csv /separator=;
In addition, you may combine multiple csv files into a one big file before importing to reduce import time.
