Export data from VB.Net Dataset to Excel without using Datagrid/DataTable




Export the data's to Excel of Microsoft office is currently need in many concern. But many of them used very complicated coding for simple export either from Datagrid or DataTable. I used simple Dataset to export the data.


Introducing the way of sending data's from datagrid or by Datatable. I used Dataset which is easy to use. But for code optimization dataset is not advisable compare to Reader and DataTable

Using the code

In current available code for export the data to Excel are given. Which are so completed and not in straight forward. Because they used the Datagrid and DataTable. Which are given below.

From DataTable to Excel sheet,

          Dim dt1 As New DataTable
          Dim I1, J1 As Integer
          For I1 = 0 To dsmas1.Tables(0).Columns.Count - 1
           For I1 = 0 To dsmas1.Tables(0).Rows.Count - 1
                Dim DR As DataRow = Nothing
                DR = dt1.NewRow
                For J1 = 0 To dsmas1.Tables(0).Columns.Count - 1
                    DR.Item(J1) = dsmas1.Tables(0).Rows(I1).ItemArray(J1)
           Dim dt As New DataTable
           Dim I, J As Integer
           For I = 0 To dschd1.Tables(0).Columns.Count - 1
           For I = 0 To dschd1.Tables(0).Rows.Count - 1
                Dim DR As DataRow = Nothing
                DR = dt.NewRow
                For J = 0 To dschd1.Tables(0).Columns.Count - 1
                    DR.Item(J) = dschd1.Tables(0).Rows(I).ItemArray(J)

For DataGrid to Excel sheet

        'verfying the datagridview having data or not
        If ((DataGridView1.Columns.Count = 0) Or (DataGridView1.Rows.Count = 0)) Then
            Exit Sub
        End If

        'Creating dataset to export
        Dim dset As New DataSet
        'add table to dataset
        'add column to that table
        For i As Integer = 0 To DataGridView1.ColumnCount - 1
        'add rows to the table
        Dim dr1 As DataRow
        For i As Integer = 0 To DataGridView1.RowCount - 1
            dr1 = dset.Tables(0).NewRow
            For j As Integer = 0 To DataGridView1.Columns.Count - 1
                dr1(j) = DataGridView1.Rows(i).Cells(j).Value

        Dim excel As New Microsoft.Office.Interop.Excel.ApplicationClass
        Dim wBook As Microsoft.Office.Interop.Excel.Workbook
        Dim wSheet As Microsoft.Office.Interop.Excel.Worksheet

        wBook = excel.Workbooks.Add()
        wSheet = wBook.ActiveSheet()

        Dim dt As System.Data.DataTable = dset.Tables(0)
        Dim dc As System.Data.DataColumn
        Dim dr As System.Data.DataRow
        Dim colIndex As Integer = 0
        Dim rowIndex As Integer = 0

        For Each dc In dt.Columns
            colIndex = colIndex + 1
            excel.Cells(1, colIndex) = dc.ColumnName

        For Each dr In dt.Rows
            rowIndex = rowIndex + 1
            colIndex = 0
            For Each dc In dt.Columns
                colIndex = colIndex + 1
                excel.Cells(rowIndex + 1, colIndex) = dr(dc.ColumnName)


        Dim strFileName As String = "D:\ss.xls"
        Dim blnFileOpen As Boolean = False
            Dim fileTemp As System.IO.FileStream = System.IO.File.OpenWrite(strFileName)
        Catch ex As Exception
            blnFileOpen = False
        End Try

        If System.IO.File.Exists(strFileName) Then
        End If

        excel.Visible = True 

But i used only Dataset to Excel sheet

In code, I used a user defined function called "Load_Excel_Details()" which i used old technique like create Object for Excel, add the Book for a sheet and sheet for the data.


  • Excel <-- System.Runtime.InteropServices.Marshal.ReleaseComObject(Excel)
    • Book <------ Excel Workbooks.Add()
      • Sheet <----- Excel SheetsInNewWorkbook = 1
        • Data <----- Excel cells(1, i).value

Which is used in the code like given below:

 With Excel
       .SheetsInNewWorkbook = 1

      Dim i As Integer = 1
      For col = 0 To ComDset.Tables(0).Columns.Count - 1
           .cells(1, i).value = ComDset.Tables(0).Columns(col).ColumnName
           .cells(1, i).EntireRow.Font.Bold = True
           i += 1

            i = 2

       Dim k As Integer = 1
       For col = 0 To ComDset.Tables(0).Columns.Count - 1
          i = 2
          For row = 0 To ComDset.Tables(0).Rows.Count - 1
              .Cells(i, k).Value = ComDset.Tables(0).Rows(row).ItemArray(col)
               i += 1
               k += 1
          filename = "c:\File_Exported.xls"
 End With


Points of Interest

I used simple For loops.... and insert the values by Rows, Columns and Cells formats.


I proposed this after i used in my company project which appreciate by the customers.
