What alternative PHP libraries or tools can be used to generate Excel files without encountering issues related to unreadable content in Excel?

When generating Excel files using certain PHP libraries or tools, issues may arise where the content in the Excel file becomes unreadable due to formatting or encoding problems. To avoid this, one alternative solution is to use the PHPSpreadsheet library, which is a more reliable and feature-rich tool for generating Excel files in PHP. PHPSpreadsheet provides better support for various Excel features and formats, reducing the likelihood of encountering unreadable content issues.

// Include the PHPSpreadsheet library
require 'vendor/autoload.php';

// Create a new Excel spreadsheet
$spreadsheet = new PhpOffice\PhpSpreadsheet\Spreadsheet();

// Add data to the spreadsheet
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello');
$sheet->setCellValue('B1', 'World');

// Save the spreadsheet as an Excel file
$writer = new PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
$writer->save('hello_world.xlsx');
