Sample would be like this:
Code:
column 1,column 2,column 3,column 4,column 5,column 6,column 7,column 8,column 9,column 10
12310,42324564756,"a simple string with a , comma","string with or, without commas",string 1,USD,12,70%,08/01/2013,
23455,12312255564,"string, with, multiple, commas,string with or, without commas",string 2,USD,433,70%,07/15/2013,
23525,74535243123,"string , with commas, and - hypens and: semicolans","string with or, without commas",string 1,CAND,744,70%,05/06/2013,
46476,15467534544,"lengthy string, with commas, multiple: colans","string with or, without commas",string 2,CAND,388,70%,09/21/2013,

Output expected:
Code:
column 1,column 2,column 3,column 4,column 5,column 6,column 7,column 8,column 9,column 10
12310,42324564756,"a simple string with a , comma","string with or, without commas",,USD,12,70%,08/01/2013,
23455,12312255564,"string, with, multiple, commas,string with or, without commas",,USD,433,70%,07/15/2013,

processcsv.py

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       processcsv.py - process virt-top CSV files

SUMMARY

	virt-top --csv data.csv
	processcsv.py < data.csv

DESCRIPTION

       virt-top is a top(1)-like utility for showing stats of virtualized domains.

       processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".

       It is used like this:

	virt-top --csv data.csv
	processcsv.py < data.csv

       The second command will overwrite the following files in the current directory:

       "global.csv"
	   This contains the global (host) statistics columns from the CSV file.

       "domainNN.csv" (multiple files)
	   For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
