Lines 588 to 604 in b791041

	function checkFile(file) {
	console.log(file.type);
	if (
	file.type === 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' ||
	file.type === 'application/wps-office.xlsx'
	) {
	readExcel(file);
	} else if (
	file.type === 'text/csv' ||
	file.type === 'application/vnd.ms-excel' ||
	file.type === 'text/comma-separated-values'
	) {
	readCSV(file);
	} else {
	pushToast($t('wish.excel.errorInvalidFile') + ` [${file.type}]`, 'error');
	}
	}

The following MIME types are valid for excel

application/haansoftxlsx
application/kset
application/vnd.ms-excel.12
 x-softmaker-pm

The rest of these are unclear whether they should be handled as CSV or XLSX, but are valid:

application/excel
application/x-excel
application/x-msexcel
application/docxconverter
