Exporting all Charts as PNG

Question

I'm trying to export all charts within my Excel file as a PNG image. The charts are not embedded in the worksheets, but have instead been moved as a new sheet upon creation.

Not being familiar with VBA or office macros, I've tried stringing together something based on code examples I found on the web but with no success.

Here's what I've tried, which may work with charts embedded within worksheets but not with standalone charts:

Private Sub ExportChartsButton_Click()
    Dim outFldr As String
    Dim ws As Worksheet
    Dim co As ChartObject

    outFldr = GetFolder(ActiveWorkbook.Path) 
    For Each ws In ActiveWorkbook.Worksheets
        For Each co In ws.ChartObjects
            co.Export outFldr & "\" & ws.Name & ".png", "PNG"
        Next
    Next
End Sub

When the button is clicked, nothing seems to happen.

If I replace the inner loop with MsgBox co.ChartObjects.Count I get a 0 popup for each of my non-chart worksheets, so I'm obvious not iterating through the right objects (hence, no charts so nothing happens).

So, how do I iterate through Charts that are not embedded within worksheets?

I found a solution. I had to use ActiveWorkbook.Charts instead of .Worksheets.

Private Sub ExportChartsButton_Click()
    Dim outFldr As String
    Dim wc As Chart
    Dim co As ChartObject

    outFldr = GetFolder(ActiveWorkbook.Path)
    If outFldr = "" Then
        MsgBox "Export Cancelled"
    Else
        For Each wc In ActiveWorkbook.Charts
            wc.Export outFldr & "\" & wc.Name & ".png", "PNG"
        Next
    End If
End Sub

And for the record, GetFolder() is defined as:

Function GetFolder(strPath As String) As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select folder to export Charts to"
        .AllowMultiSelect = False
        .InitialFileName = strPath
        If .Show = True Then sItem = .SelectedItems(1)
    End With
    GetFolder = sItem
    Set fldr = Nothing
End Function

Comments/suggestions very welcome.

Perhaps one of the easiest way to export by far is to save the whole workbook as a webpage. Excel will then automatically convert your charts to PNG's
