This is unfortunately not possible with openpyxl. You'll have to use xlwt (for the legacy Excel format) or xlsxwriter (for the current Excel format).

See https://foss.heptapod.net/openpyxl/openpyxl/-/issues/1503 for confirmation that openpyxl does not (and likely will never) support this functionality.

For more information on xlwt see https://pypi.org/project/xlwt/.

For more information on xlsxwriter see https://pypi.org/project/XlsxWriter/.
