what are the relevant differences between this libs ? also can tell me anyone about the license of this products ?
i need to generate large files .xlsx files. Until now i used jxl lib in for .xls with a a formated header using jxl.write.WritableCellFormat.
1) JXL is now JExcel.
2) You can get all list of differences between JExcel and Apache POI here
3) Both are free.
4)You should use Apache POI because JExcel does not support .xlsx format.
