What are the potential pitfalls of processing Excel files in PHP instead of using CSV files?

Processing Excel files in PHP can be more complex and resource-intensive compared to CSV files. Excel files require additional libraries such as PHPExcel or PhpSpreadsheet, which can increase the complexity of the code and potentially slow down processing. Additionally, Excel files may contain formatting and formulas that need to be handled properly to avoid data corruption or loss. 

// Example of processing a CSV file instead of an Excel file in PHP

$file = 'data.csv';
$handle = fopen($file, 'r');

while (($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
    // Process each row of data
    // Example: echo $data[0]; // Output the first column of each row
}

fclose($handle);
