shuchkin/simplexlsxgen, how to prevent Decimal dott from changing to comma

i am using (shuchkin/simplexlsxgen) to generate xlsx file which works fine. My data contain decimal numbers such as (0.19) which are written in the SQL DB, but instead writting them with dott, the (simplexlsxgen) convert them to (0,19) php error comma decimal numbers. is there a way to prevent changing the decimal Dott to comma, before generating? Thanks in advance.

//convert test_bulk.csv to Xlsx function csvToArray($csvFile) {     $file_to_read = fopen($csvFile, 'r');    while (!feof($file_to_read))    {        $lines[] = fgetcsv($file_to_read, 1000, ';');    }    fclose($file_to_read);    return $lines; } //read the csv file into an array $csvFile = 'test_bulk.csv'; $csv = csvToArray($csvFile); Shuchkin\SimpleXLSXGen::fromArray($csv)->saveAs('final_bulk.xlsx');
