I'm trying to fetch the data from database using the query and then print it into excel. so,for that, we need to set format for the field dynamically. I've tried all the cases but it is not working.I'm sharing the part of the code.

my $row2=1;

         while(my @field=$sth2->fetchrow_array){
                my $col2=0;
                my $arr_ref=\@field;
               # print "$field[19]\n";--> This is my field and this is
+ where I need to set the custom format.
                $worksheet2->write_row($row2,0,$arr_ref);
                $row2++;
}
