see foreach loops in perlsyn. Your foreach loop iterates over the list values of 0 to 9 and sets the scalar variable $data to be each element of the list in turn. Because the variable is preceded with the keyword my, then it is lexically scoped, and is therefore visible only within the loop.

Try

#!/usr/bin/perl
use strict;
use Spreadsheet::Read;

my $excel = ReadData("TEST.csv");

my $maxrow = $excel->[1]{maxrow};
for my $row (1 .. $maxrow){
  my $url = $excel->[1]{'A'.$row};
  # do something with url
  process($url);
}

sub process {
  my ($url) = @_;
  print "Processing $url\n";
}
