Hello, When exporting to excel, i need excel to detect cell type as format hh:mm and [h]hh:mm, it's basically a time interval., so I can perform excels SUM on selected fields and get result in format [h]hh:mm. This is possible when doing manully in excel. My input data is also of format hh:mm.cell type detection is turned on. tried sending it as string, ofc excel detects that as string. tried parsing it using SimpleDateFormat("HH:mm").parse("15:35")[/code] , excel detects that as date and time (something like "1/1/1970 15:35"), while I just need the time. tried using net.sf.jasperreports.export.xls.pattern, that gives nice look of data, but nature of data in cell is still date and time. So is there a way to export to excel and have excel cell data to be excels time hh:mm and /or [h]hh:mm format? Thank you
