Hi Akshay,
A slight modification in the structure of data. Actually the input file is in this format below
HTML Code:
"a1","b1","c1","d1"
"a2","b2","c2","d2"
"a3","b3","c3","d3"
"a4","b4","c4","d4"
The compare file will be
HTML Code:
C2,
C4,
The provided code doesn't work if it is enclosed in double quotes.
How can I check for only the text in upper case ignoring the double quotes?

Thanks

No surprise that code doesn't work, as your latest sample input is different from earlier one (case & double quotes).

Use this code

Code:
$ awk -F, 'FNR==NR{A[tolower(q $1 q)];next}!(tolower($3) in A)' q='"' compare.txt input.txt
