Open XLSX file that protected by a password with PHPSpreadsheet - php

Question

I'm trying to open an Excel file (.xlsx) that is protected by a password with PHPSpreadsheet (documentation). I know the password but I don't find a way to open it.
The load()method of \PhpOffice\PhpSpreadsheet\Reader\Xlsx doesn't give the possibility to insert a password and when I try to load the file it returns an error (of course).
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
$spreadsheet = $reader->load('hello world.xlsx');
$sheet = $spreadsheet->getActiveSheet();
echo $sheet->getCell('A1')->getValue() . "\n";
And here is the error
Warning: ZipArchive::getFromName(): Invalid or uninitialized Zip object in /PHPOffice/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Reader/Xlsx.php on line 311
Warning: ZipArchive::getFromName(): Invalid or uninitialized Zip object in /PHPOffice/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Reader/Xlsx.php on line 313

How can this code deal with passwords?

Answer 1

I welcome you to check out my PHPDecryptXLSXWithPassword repo.
It also works for DOCX/PPTX files, but this answer is specific to your question: first decrypt the file with password, and then use the decrypted file with PHPSpreadsheet.
Here is an example:
require_once('PHPDecryptXLSXWithPassword.php');
$encryptedFilePath = 'hello world.xlsx';
$password = 'mypassword'; // password to "open" the file
$decryptedFilePath = 'temp_path_to_decrypted_file.xlsx';
decrypt($encryptedFilePath, $password, $decryptedFilePath);
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
$spreadsheet = $reader->load($decryptedFilePath);
$sheet = $spreadsheet->getActiveSheet();
echo $sheet->getCell('A1')->getValue() . "\n";
Note: This is an experimental code, so use with caution. DO NOT use in production!

Answer 2

At this moment i can't try but, I suppose that you have to do something like this:
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Xlsx();
$spreadsheet = $reader->load('hello world.xlsx');
$sheet = $spreadsheet->getActiveSheet();
$sheet->getProtection()->setSheet(true);
$sheet->getProtection()->setPassword('THEPASSWORD');
echo $sheet->getCell('A1')->getValue() . "\n";
I'm not sure, tomorrow I will be to the office and can try.
