Export closed captions in bulk?

Hello. Another user looking for being able to bulk export. I was hoping to a quick and easy way to do a full spelling check on all the captions that I entered. I have 21 scenes and too many slides and layer to count, so exporting one at a time is just not an option, I'm better off just going through and reading each one a couple times and crossing my fingers all are caught. If I could export everything to a word doc, can easily run a spell check and correct errors.
