PHPExcel Make first row bold

January 24, 2023 by Tarik

Try this for range of cells:

$from = "A1"; // or any value
$to = "B5"; // or any value
$objPHPExcel->getActiveSheet()->getStyle("$from:$to")->getFont()->setBold( true );

or single cell

$cell_name = "A1";
$objPHPExcel->getActiveSheet()->getStyle( $cell_name )->getFont()->setBold( true );
