Question

I have table consist of column(“file as pdf”) which stores the bills.

my problem is i want to export that table to excel sheet.

is it possible?

So far i tried this..

 Dim xapp As New Microsoft.Office.Interop.Excel.Application
    Dim wb As Workbook = xapp.Workbooks.Add
    Dim ws As Worksheet = wb.Worksheets(1)
    ws.Activate()

    'Fill header of the sheet----------------------------------

    For i As Integer = 1 To dgvcustomer.Columns.Count
        ws.Cells(1, i) = dgvcustomer.Columns(i - 1).HeaderText
    Next

    'End header------------------------------------------------

    Dim Dgrow, Dgcell, Dgcol As Integer
    Dgrow = 1
    Dgcell = 1

    'Fill Sheet -----------------------------------------------------------------------

    While (Dgrow <= dgvcustomer.Rows.Count)
        Dgcol = 1
        While (Dgcol <= ws.UsedRange.Columns().Count)
            ws.Cells(Dgrow + 1, Dgcol).value = dgvcustomer.Rows(Dgrow - 1).Cells(ws.Cells(1, Dgcol).value).Value
            Dgcol += 1
        End While
        Dgrow += 1
    End While

    'End fill sheet--------------------------------------------------------------------

    wb.SaveAs(dlgSaveFile.FileName)
    wb.Close()
    xapp.Quit()

This code works for non blob data type columns but for blob it raises exception.

Answer 1

No. Excel does not support storing data blobs in cells of worksheets.

You should probably export these PDFs each to individual files, and specify the file name in the exported worksheet.
