PHPOffice/PhpSpreadsheet: Reset cell style

In the docs

• https://phpspreadsheet.readthedocs.io/en/develop/
• https://phpoffice.github.io/PhpSpreadsheet/master/PhpOffice.html

i didn't find any useful function for my need.

Is it possible to "reset" / "delete the entire formatting" of a single cell? Return the cell to its original state.

explicitly undoing the previous format should work:

$ws->getStyle('A1')->applyFromArray(array(
    'font' => array('bold' => false)
));

when importing, one can also skip formats altogether: $reader->setReadDataOnly(true);
