What best practices can be followed to ensure correct formatting of font, color, and alignment in PHPExcel?

To ensure correct formatting of font, color, and alignment in PHPExcel, it is best to set these properties for cells individually. This can be done by accessing the cell object and then setting the desired formatting options using the appropriate methods provided by PHPExcel.

// Set font, color, and alignment for a specific cell
$sheet->getStyle('A1')->getFont()->setBold(true);
$sheet->getStyle('A1')->getFont()->setColor(new PHPExcel_Style_Color(PHPExcel_Style_Color::COLOR_RED));
$sheet->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
