33    Only required file is this script C<< sql2xls.cgi >>
34    
35    If your server is configured to execute C<.cgi> files, you can

41    
42    To configure default database, user, password and other settings create
43    C<config.pl> file in same directory in which C<sql2xls.cgi> is with something
44    like this:
45    
46      $dsn      = 'DBI:mysql:dbname=';
47      $database = 'database';
48      $user     = 'user';
49      $passwd   = 'password';
