You can get idea in my code, I generate file from word template file save file as pdf using Office.Interop. Dont forget to add reference the office.Interop.Word

    sFileName = "billing"
    wdApp = New Word.Application
    wdDocs = wdApp.Documents

    Dim wdDoc As Word.Document = wdDocs.Add(sPath & "template.dotx")
    Dim wdBooks As Word.Bookmarks = wdDoc.Bookmarks
    Dim wdTable As Word.Table


    Dim r As Integer, c As Integer
    wdTable = wdDoc.Tables.Add(wdDoc.Bookmarks.Item("bkTable").Range, 3, 6)
    Dim rowCOunt As Integer = dgvSample.Rows.Count, colCount As Integer = dgvSample.Columns.Count

    'DATAGRIDVIEW TO WORDTABLE
    For r = 1 To rowCOunt
        For c = 1 To colCount
            wdTable.Cell(r, c).Range.Text = dgvSample.Rows(r - 1).Cells(c - 1).Value
        Next
    Next

    wdTable.Borders.InsideLineStyle = Word.WdLineStyle.wdLineStyleSingle
    wdTable.Borders.OutsideLineStyle = Word.WdLineStyle.wdLineStyleSingle

    wdBooks("bkClient_name").Range.Text = txtClient.Text.ToString
    wdBooks("bkDate").Range.Text = dtpDate.Text.ToString
    wdDoc.SaveAs2(sPath & sFileName & ".pdf", Word.WdSaveFormat.wdFormatPDF)

    ReleaseObject(wdBooks)
    wdDoc.Close(False)
    ReleaseObject(wdDoc)
    ReleaseObject(wdDocs)
    wdApp.Quit()
