Paste Excel range in Outlook

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b̶u̶t̶c̶h̶e̶r̶e̶d̶ modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

Sub Mail_Selection_Range_Outlook_Body()

Dim rng As Range
Dim OutApp As Object
Dim OutMail As Object

Set rng = Nothing
' Only send the visible cells in the selection.

Set rng = Sheets("Sheet1").Range("D4:D12").SpecialCells(xlCellTypeVisible)

If rng Is Nothing Then
    MsgBox "The selection is not a range or the sheet is protected. " & _
           vbNewLine & "Please correct and try again.", vbOKOnly
    Exit Sub
End If

With Application
    .EnableEvents = False
    .ScreenUpdating = False
End With

Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)


With OutMail
    .To = ThisWorkbook.Sheets("Sheet2").Range("C1").Value
    .CC = ""
    .BCC = ""
    .Subject = "This is the Subject line"
    .HTMLBody = RangetoHTML(rng)
    ' In place of the following statement, you can use ".Display" to
    ' display the e-mail message.
    .Display
End With
On Error GoTo 0

With Application
    .EnableEvents = True
    .ScreenUpdating = True
End With

Set OutMail = Nothing
Set OutApp = Nothing
End Sub


Function RangetoHTML(rng As Range)
' By Ron de Bruin.
    Dim fso As Object
    Dim ts As Object
    Dim TempFile As String
    Dim TempWB As Workbook

    TempFile = Environ$("temp") & "/" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"

    'Copy the range and create a new workbook to past the data in
    rng.Copy
    Set TempWB = Workbooks.Add(1)
    With TempWB.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial xlPasteValues, , False, False
        .Cells(1).PasteSpecial xlPasteFormats, , False, False
        .Cells(1).Select
        Application.CutCopyMode = False
        On Error Resume Next
        .DrawingObjects.Visible = True
        .DrawingObjects.Delete
        On Error GoTo 0
    End With

    'Publish the sheet to a htm file
    With TempWB.PublishObjects.Add( _
         SourceType:=xlSourceRange, _
         Filename:=TempFile, _
         Sheet:=TempWB.Sheets(1).Name, _
         Source:=TempWB.Sheets(1).UsedRange.Address, _
         HtmlType:=xlHtmlStatic)
        .Publish (True)
    End With

    'Read all data from the htm file into RangetoHTML
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set ts = fso.GetFile(TempFile).OpenAsTextStream(1, -2)
    RangetoHTML = ts.ReadAll
    ts.Close
    RangetoHTML = Replace(RangetoHTML, "align=center x:publishsource=", _
                          "align=left x:publishsource=")

    'Close TempWB
    TempWB.Close savechanges:=False

    'Delete the htm file we used in this function
    Kill TempFile

    Set ts = Nothing

End Function

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:
