Public Sub export_me_to_excel(ByVal list As ListView)
    Try
        Dim objExcel As New Excel.Application
        Dim bkWorkBook As Workbook
        Dim shWorkSheet As Worksheet
        Dim chartRange As Excel.Range
        Dim i As Integer
        Dim j As Integer

        objExcel = New Excel.Application
        bkWorkBook = objExcel.Workbooks.Add
        shWorkSheet = CType(bkWorkBook.ActiveSheet, Worksheet)
        shWorkSheet.DisplayRightToLeft = True

        chartRange = shWorkSheet.Range("a1", "e2")
        chartRange.Merge()
        chartRange.FormulaR1C1 = xlval

        chartRange.HorizontalAlignment = 2
        chartRange.VerticalAlignment = 2

        For i = 0 To list.Columns.Count - 1
            shWorkSheet.Cells(5, i + 1) = list.Columns(i).Text
            shWorkSheet.Columns.AutoFit()
            shWorkSheet.Columns.HorizontalAlignment = Excel.Constants.xlCenter
            shWorkSheet.Columns.BorderAround(Excel.XlLineStyle.xlContinuous, Excel.XlBorderWeight.xlMedium, Excel.XlColorIndex.xlColorIndexAutomatic, Excel.XlColorIndex.xlColorIndexAutomatic)

        Next
        For i = 0 To list.Items.Count - 1
            For j = 0 To list.Items(i).SubItems.Count - 1

So, you wrote a piece of code and decided to throw it at anything that mentions exporting to Excel from a ListView?

Unexplained answers are useless.

Going from a listview to a .csv file for Excel isnt hard - in fact, if you look here FileHelpers Library[^] you can probably use that for 1/2 the work - it looks like you'll still need to iterate your listview and build an a list of objects, where a object represents a row and the information within the columns (or perhaps, listview -> DataTable might be an option)

PDF - a couple of options - there's this PDF File Writer C# Class Library (Version 1.19.0 Enhancement: Document links)[^] or iTextSharp ... I cant recall what Uzi's library uses to format a PDF table, some time looking at his examples may help you optimise the data-structure for the export to csv step.
