Hello everybody,

I have been struggling with a problem for a while. I have some presentations in spanish, but powerpoint (on Macbook) detects it as english and marks all words as spelling mistakes. I need to be able to mark all the boxes from all the slides as "Spanish" to make the spelling mistake detections disappear and make Powerpoint understand that the whole presentation is in Spanish. I have tried all "simple" solutions for a while without success, and I am now asking for help to build a macro to do it. I have seen in the youtube video (link below) that they have built such a macro working on Microsoft, and I would need the same for Macbook.

Is anybody here able to help me?
