What are the best practices for handling Excel files in PHP to avoid data corruption or loss?

When handling Excel files in PHP, it is important to use the appropriate libraries and functions to prevent data corruption or loss. One common approach is to use a library like PHPExcel or PHPSpreadsheet, which provide robust methods for reading, writing, and manipulating Excel files. Additionally, it is crucial to validate user input and sanitize data to prevent any malicious code from being executed. 

// Example using PHPSpreadsheet library to handle Excel files
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

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

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

// Save the spreadsheet to a file
$writer = new Xlsx($spreadsheet);
$writer->save('hello_world.xlsx');
