Remove line feed from csv file column

Hi All,

i have a csv file .
In the 7th column i have data that has line feed in it.
Requirement is to remove the line feed from the 7th column whenever it appears

There are 11 columns in the file
C1,C2,C3,C4,C5,C6,C7,C8,C9,C10,C11

The value in C7 contains line feed ( Alt + Enter ), since the end of the line is also line feed value is C7 is pushed to different line .

1) 1,b2,c3,d4,e5,f6,here comes the line feed ,g8,h9,i10
                    this is pushed to second line 
 
the output is :
 
1,b2,c3,d4,e5,f6,here comes the line feed
this is pushed to second line , g8,h9,i10

kindly advice

 awk -F"," '{if(NF>7){for(i=8;i<=NF;i++){a=a","$i;$i=""};NF=7;print $0;getline;gsub(/^ */,"");OFS="";print $0,a}else{print $0}}' OFS="," file.csv
use Text::CSV;  
   
my $csv = Text::CSV->new({binary=>1});  
   
#NOTE: Replace input.txt with your actual filename  
open(my $in, "<input.txt") or die "input: $!\n";  
   
#NOTE: Replace output.txt with the name you want for your new file  
open(my $out, ">output.txt") or die "output: $!\n";  
   
while(my $colref = $csv->getline ($in)) {  
        s/[\r\n]//g foreach (@$colref);  
        $csv->combine(@$colref);  
        print $out $csv->string . "\n";  
}  
close($in);  
close($out);
