If you don't know what type of file it is (commas or tabs) then you may have a problem because if you convert all the commas to tabs in a file you could end up converting legitimate commas to tabs. I'm not certain if the reverse would be true. (but I would assume so). But the conversion is pretty easy:
open(FILE,"+<tabs.txt") or die "Couldn't open tabs.txt: $!";
my @file = <FILE>;
seek(FILE,0,0);
foreach(@file) {
s/\t/,/g;
print FILE $_;
}
close(FILE);
Now for putting quotes around your values:
open(FILE,"+<tabs.txt") or die "Couldn't open tabs.txt: $!";
my @file = <FILE>;
seek(FILE,0,0);
foreach(@file) {
chomp();
my $line = "";
my(@values) = split(/\,/,$_);
foreach my $value(@values) {
$value = "\"$value\"" if $value !~ /^\".*?\"$/;
$line .= "$value,";
}
chop($line);
print FILE "$line\n";
}
close(FILE);
Hope that helps
