Answer 1

You can do a column like this:

$objPHPExcel->getActiveSheet()->getStyle('M:M')
    ->getNumberFormat()
    ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_GENERAL);

A complete working example. The result in column A has two 2, column B two 2.00

$sheet = $objPHPExcel->getActiveSheet();

$sheet->getStyle('A:A')
        ->getNumberFormat()
        ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_GENERAL);

$sheet->getStyle('B:B')
        ->getNumberFormat()
        ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_NUMBER_00);

$sheet->setCellValue('A1', 2);
$sheet->setCellValue('A2', 2.0);
$sheet->setCellValue('B1', 2);
$sheet->setCellValue('B2', 2.0);

A few more examples for column and row selections that I pulled from my actual base:

$objPHPExcel->getActiveSheet()->getStyle('1:1')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->getStyle('A:A')->getNumberFormat()->setFormatCode('yyyy/mm');
$objPHPExcel->getActiveSheet()->getStyle('D:D')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('E:E')->getNumberFormat()->setFormatCode('$#,###');

Answer 2

PHPExcel doesn't support column or row styling: you need to set the style for a range of cells, exactly as you are doing with

$objPHPExcel->getActiveSheet()->getStyle('M1:M97')
->getNumberFormat()
->setFormatCode('0');

if you want General format rather than '0', then set it to General Instead:

$objPHPExcel->getActiveSheet()->getStyle('M1:M97')
    ->getNumberFormat()
    ->setFormatCode('General');

or

$objPHPExcel->getActiveSheet()->getStyle('M1:M97')
    ->getNumberFormat()
    ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_GENERAL);
