I have a long text string (1300 characters). Even with text wrapping
and expanding the cell height, it eventually (at 1200-something
characters) stops wrapping.

I want to be able to tell where the text begins to exceed the cell
width (i.e., stops wrapping), so I can end that cell nicely and put
the rest in subsequent cells. I know how to do the latter.

Is there a way to tell via (VBA) where the text begins to exceed the
cell width?

Thanks, Alan
