In my latest video on YouTube, I explain how you can export all your captions and closed captions from your Adobe Captivate project file into a MS Word document. This is a great way to get your hands on all your text, narration (with a little extra work), and closed captioning text for various reasons. Here are the reasons you may want to do this:

To have your text, narration, and closed captions translated into another language - Most people don't have Adobe Captivate on their desktop so sending them the Captivate project file is out of the question, however almost everyone uses MS Word.
To have someone else edit your captions - sometimes you may need to have someone else edit your work. Again, if they don't have Captivate software on their desktop, this isn't going to happen. Exporting to Word just makes sense.
An easy way to ensure that you have consistent use of fonts, colour, font size, and so on - I've run into this where your title is 25 point on one slide, but it's 28 on another. You could edit this in Captivate but you could also use the Format Painter in MS Word for an easy edit to all your content.
Send all text of course content to subject matter experts - This is an easy way for your subject matter experts to follow along with the course and provide suggestions or edits for your consideration. It's not a storyboard, but it's the next best thing.

What the video to learn how to export project captions and closed captions and how to import them back in as well. The video includes a few additional pointers on working with these files.
