I have an Excel workbook with 5 sheets. 4 sheets have scorecards running on macros and I need to feed data to one sheet using my application. The macros will then take data from data sheet and create the scorecards. I am usinf HSSF for this and after writing data to the sheet, I am unable to open the excel sheet. I get an error "Unable to open File". Can anyone help regarding this.
This is a question for the list. Too little information provided.
