I am trying to create double and number format cells in excel using NPOI library. I used code like
Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
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
Then While opening file it is giving error and also taking so long to open. But Excel format showing in "Number" error showing is like below.

I have a web page which I have created to allow users to upload excel file sheet and thus these sets of data will be inserted into the database. However, as I was testing out, I realized that if the excel file is too large (i.e. mulitple sheets, > 5 sheets) , the portal may not be able to handle the large amount of data and displayed error message like the connection is reset. 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?
