My need is in the exported excel, if change the amount means i should able to get the corresponding amount in the next column.
(i.e) in the exported excel, if i edit the "Amount" ->1000 to 500 means the next column "Out Of 10 Percent" should change as 100 -> 50. I mean it should be auto calculated in the exported excel.

I know 07 probably handles data a little bit different than 03 but I don't have a lot of time to dedicate to reworking this app if possible.

In excel numbers are aligning right but when I check format it is showing in "General"
then I changed my code to like below
Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString)) Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#,#0.0") cell.CellStyle = cellStyle

I tried it with only less than 5 sheets it will be fine. Any idea if there are any codes or mechanism which could solve this problem?
