The preeminence is to have every method of the formatter return the formatter as a reference. This allows it to add and format text in chain. Such as:

ShapeTextFormatter.Create(Shape).AddText("Hello ").FontSize(16).Bold(True).AddText("Cruel ").StrikeThrough(msoCTrue).FontSize(6) _
.AddText("World!").FontSize(16).Bold(True).StrikeThrough (msoFalse)

Note: Formats are applied to the last text block.

Overall, I think that it turned out okay. But I did have a few sticky points.

In a couple of cases, I had to convert range enum values to their shape counterparts. UnderLineFromRange() had a couple of its values double up. I'm not sure if there is a distinction between them or not.

The class has 20 methods and only 2 error handlers. Did I miss any?

White-Space, what white-space! Everything is so packed in. It seems like it need more white-space but where to put it? I couldn't think of a spacing pattern that made since.

Using .Clear() by itself throws an Invalid Use of Property error.

ShapeTextFormatter.Create(wsShapes.Shape1).Clear

You will need to use Call if the you use one but not all of the optional parameters. I think Call could be omitted if named parameters are used. I should probably add a big ugly banner warning to the class.

ToDo List

There are always more features that be added. It would be nice to be able to fade text using the Transparency. There are too many text effects to implement. Returning an instance of the the TextFrame2 and LastText() would probably make since. I avoided it because I didn't want to break away from the Builder Pattern.

Of course naming could almost always be improved.

Test

I intentionally switched between using Call and not using it, for demonstration purposes.
You will need to use Call if the you use one but not all of the optional parameters. I think Call could be omitted if named parameters are used.

Sub Test()
    Dim ColorRange  As Range
    Set ColorRange = wsShapes.ColorRange
    With ShapeTextFormatter.Create(wsShapes.Shape1).Clear
        Dim r As Long

        AddTextWithFormatsFromCell .Self, ColorRange.Cells(1)
        
        For r = 2 To ColorRange.Rows.Count
            AddTextWithFormatsFromCell .Self, ColorRange.Cells(r, 1), True
            Call .AddText(vbTab).Underline(msoNoUnderline)
            Call .StrikeThrough(msoFalse)
            AddTextWithFormatsFromCell .Self, ColorRange.Cells(r, 2)
        Next
    End With
End Sub

Rem Factory method used to test the ShapeTextFormatter class
Sub AddTextWithFormatsFromCell(ByVal Formatter As ShapeTextFormatter, ByRef Cell As Range, Optional ByVal AppendNewLine As Boolean)
    With Formatter.Create(wsShapes.Shape1)
        If AppendNewLine Then
            Call .AppendText(Cell.Text)
        Else
            Call .AddText(Cell.Text)
        End If
        Call .Bold(Cell.Font.Bold)
        Call .Italic(Cell.Font.Italic)
        .FontName Cell.Font.Name
        .FontSize Cell.Font.Size
        .ForeColor Cell.Font.Color
        .LineAlignment Cell.HorizontalAlignment
        .StrikeThrough Cell.Font.StrikeThrough
        .UnderLineFromRange Cell.Font.Underline
    End With
End Sub
