Hello. I edit xls file using PHPSpreadsheet and then I want to save it to pdf using mPdf.
Here is the code:

$spreadsheet = IOFactory::load(public_path('form_3.XLS'));
$worksheet = $spreadsheet->getActiveSheet()->setCellValue('N16', $data);
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf($spreadsheet);
$writer->writeAllSheets();
$writer->save("file.pdf");

What I get as a result:

What I plan to see:

Perhaps I need to transfer some other settings, but I don’t know which ones and how.
I also tried with DomPDF, but it's even worse there.
