phpspreadsheet setCellValue is not writing

问题

I am uploading a excel file, reading the contents and writing to a new excel file using phpspreadsheet.

I am trying to create a excel file.

I am writing into cells using the following code

$writesheet->setActiveSheetIndex(0)->setCellValue('A1','myemail@gmail.com');

these lines

        echo 'valid';
        echo $cell;
        echo $toemail;

print all the values correctly.

But this line of code is not working..

Full code:

<?php
include '../includes/common.php';
include "class.emailvalidator.php";

Try running $writer->setPreCalculateFormulas(false); - fixed it for me
