Replacing the text in a row based on certain condition
Hi All,
I felt tough to frame my question. Any way find my below input. (.CSV file)

Code:
SNo, City
1, Chennai
2, None
3, Delhi
4,None

Note that I have many rows ans also other columns beside my City column.

What I need is the below output.
Code:
SNo, City
1, Chennai
2, Chennai_new
3, Delhi
4, Delhi_New

So in the 2nd column whenever I see "None" I should change it to immediate above row value_new(or any text).

I hope I made myself clear on requirement.

Thanks
Sid
