@dlintw Thanks for your issue. This library just supports Excel's built-in formats currently. The built-in number formats index (numFmtId) in the attachment is out of this range. I will handle this exception by returning the raw value. You can use function SetCellStyle() with built-in number format index by number_format property before GetRows().
