If you find that when you export a Ragic form as an Excel file, the ROC date format is displayed as AD date format in Excel, it may be because your Excel does not currently support the ROC date format. Therefore, the exported data from Ragic will be automatically converted into AD date format.
If your computer is a Windows system, you can refer to this webpage (or search for other solutions online) to set up Excel to support the ROC date format: https://it-help.tips/windows-10-excel-install-microsoft-windows-internationalfeatures-taiwan-package
If you are using WPS Excel or Mac version of Microsoft Excel, both do not currently support the ROC date format.
