I receive PowerPoint presentations in PowerPoint 2013 with a variety of text boxes and shapes with text in them. Some have spelling errors but I find that the spell check does not detect them as the checkbox 'do not check spelling' has been ticked. I'm looking, so far without success, for a macro that will trip through all the boxes and shapes on all t he slides, and change the language to English UK and unpick the box so the spellcheck will apply.
I cannot find the syntax for the second part of the problem on the checkbox, can anyone help?
