In what scenarios would using CSV as an alternative to xlsx be more suitable when working with Excel files in PHP?

When working with Excel files in PHP, using CSV as an alternative to xlsx may be more suitable in scenarios where compatibility with different versions of Excel is important, when the file size needs to be minimized, or when the data does not require complex formatting or formulas. 

// Read data from a CSV file
$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');
if ($handle !== false) {
    while (($data = fgetcsv($handle, 1000, ',')) !== false) {
        // Process each row of data
        print_r($data);
    }
    fclose($handle);
} else {
    echo 'Error opening file';
}
