If you want to keep commas as part of a string in any CSV file, you have to delimit the whole string column with double quotes. In fact, it's a good idea to always use double quotes around any string in a CSV file:
1,"abc","140 abc,xyz,delhi",10001,"xxx","sss"
To include double quotes in a double quoted string, double them:
1,"abc","140 abc,""xyz"",delhi",10001,"xxx","sss"
Will give you these columns:
1
abc
140 abc,"xyz",delhi
10001
xxx
sss
