How to insert " " in between column in a file

[faizalms]

Guys,

I'm quite new with awk and wanna do something like this:
let say i have a file with this content :
aaaa,bbbb,cccc,dddd

and i wanna do an insert of " " only on the third column. and the output to be like this :

aaaa,bbbb,"cccc",dddd

fyi, the file contains millions rows and i need to consistently insert " " on the third column.

Please help. Your solution really will save my time a lot!

Cheers,
Faizals

Not very familiar with awk myself, but you could try the following:
awk -F"," '{print $1","$2",\""$3"\","$4}' test.txt

This assumes you use the comma (,) as seperator and that there are 4 columns.
