Skip empty cells in range

Question

I have code to select a specified range and paste it into an e-mail. I would like to skip copying blank cells and paste only the cells that contain data.

The range should stay the same as it is a table filled from external sources. Sometimes cells might be blank and at other times different cells will be blank. At times no cells will be blank.

I tried constants. It would then only paste the range C13:J13. This is the only row that hasn't any formulae in the cells, only text. All other cells within the range have formulae. I guess it would be best to check whether length <1 then skip.

Sub PrepareMailOffer()
    Dim rng As Range
    Dim OutApp As Object
    Dim OutMail As Object

    Set rng = Nothing
    On Error Resume Next

    Set rng = Sheets("000000").Range("C12:J29").SpecialCells(xlCellTypeVisible)
    On Error GoTo 0

    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)

    On Error Resume Next
    With OutMail
        .To = Range("N4").Value
        .CC = ""
        .BCC = ""
        .Subject = ""
        .HTMLBody = "" & _
            RangetoHTML(rng) & _
            "" & _
        .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)
    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 paste 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
    Set fso = Nothing
    Set TempWB = Nothing
End Function

The code works when I have no blank cells.

Answer 1

Please, try the next adapted code, which hides the blank rows (even with blank from formula) and process the visible cells of resulted range:

Sub PrepareMailOffer()
    Dim ws As Worksheet, rng As Range, rngH As Range, i As Long
    Dim OutApp As Object, OutMail As Object

    Set ws = Sheets("000000")
    Set rng = ws.Range("C12:J29")

    'place the blank rows in a Union range and hide them, at once:
    For i = 1 To rng.rows.count
       If WorksheetFunction.CountBlank(rng.rows(i)) = rng.Columns.count Then
           addToRange rngH, rng.rows(i).EntireRow
       End If
    Next i
    If Not rngH Is Nothing Then rngH.EntireRow.Hidden = True 'hide the blank rows
    
    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With

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


    With OutMail
        .To = Range("N4").Value
        .cc = ""
        .BCC = ""
        .Subject = ""
        .HTMLBody = "" & _
            RangetoHTML(rng.SpecialCells(xlCellTypeVisible)) & _
            "" & _
        .Display
    End With
    
    If Not rngH Is Nothing Then rngH.EntireRow.Hidden = False 'unhide the previous hidden rows
    
    With Application
        .EnableEvents = True
        .ScreenUpdating = True
    End With

    Set OutMail = Nothing
    Set OutApp = Nothing
End Sub

Sub addToRange(rngU As Range, rng As Range)
    If rngU Is Nothing Then
        Set rngU = rng
    Else
        Set rngU = Union(rngU, rng)
    End If
End Sub

On Error Resume Next in your code context only do not let you know what error you have, if any...

You should use the same (existing) RangetoHTML function...

Please, send some feedback after testing it.
