Hi, you have a bug in your code.

In the xlsx parsing portion the code fragment here:

if ($cell) {
$aggregated_x .= $cell->{Val}.',';
}
}
$aggregated_x .= "\n";

should actually read:

if ($cell) {
$aggregated_x .= $cell->{Val}.',';
}

else {
$aggregated_x .= ',';
}

}
$aggregated_x .= "\n";
}

Otherwise the xlsx parsing function will ignore blank cells, a huge problem for CSV files!

Kind regards,

JB.

where i must send my file pl and eccel in my cpanel root?

but to use this script i must install xls2csv in my server ??? how can i do in shared hosting with cpanel ?
