How can a text field be designated to belong to a specific column category when importing CSV data into Excel or Power BI?

When importing CSV data into Excel or Power BI, a text field can be designated to belong to a specific column category by specifying the data type for that column. This can be done by selecting the column in the import wizard and choosing the appropriate data type (e.g. text, date, number) from the dropdown menu. This ensures that the text field is correctly interpreted and displayed in the designated column category.

$worksheet->getStyle('A')->getNumberFormat()->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_TEXT);
$worksheet->getStyle('B')->getNumberFormat()->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_DATE_YYYYMMDD2);

// Save the modified spreadsheet
$writer = PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
