lobjExcelApp = New Excel.Application
lobjExcelApp.Visible = False

lobjExcelWrkBk = lobjExcelApp.Workbooks.Open(strSourceFilePath, , ReadOnly:=True)

lobjsht = lobjExcelWrkBk.Sheets("Sheet1")
lobjExcelWrkBk = lobjExcelApp.ActiveWorkbook

lobjsht.Range("A2").CopyFromRecordset(ors)
lobjExcelWrkBk.SaveAs(strDestinationFileName)
lobjExcelApp.Quit()

Catch
End Try

The whole point of Excel Interop is that you interoperate with Excel. If Excel is not installed then there's nothing to interoperate with, hence the error. If you want to make use of Excel functionality then you need Excel installed. If you can't install Excel then you can't make use of its functionality. In that case you might have to use CSV files, which can be opened in Excel, instead of XLS files.

Thanks jmcilhinney,

I am using xlsx (Excel 2007). so I am not able to csv as xlsx. The exporting should be xlsx only.

Then you'll need to have Excel 2007 installed.

If you want to create a XLSX file then you need something that understands the XLSX format to do it. The obvious choice there is Excel itself.

Alternatively, you could use a component that is specifically designed to interact with XLSX files. I'm sure there are .NET components that will do it but I doubt that they're cheap.

The final option would to research the XLSX format, which is open, and write code to create the file yourself. That's not going to be a trivial exercise though, which is why components to do it for you would not be cheap.

Thanks jmcilhinney,

I will do some analysis regarding this.
