I found the answer to my post, and hope it helps others:
Instead of trying to export from Frontpage, I found a way to essentially spider my own site for meta tags. It's very useful because you can designate a folder or even single text file of your URLs, and it will retrieve the metas and subsequently allow you to save/export those to csv/excel. It took me a long time searching. If you're looking for this type of thing, it's called URL Meta Tag 2.0 aka Online Data Extractor. It's not freeware, and they have a trial, but it's definitely worth it. Best nav is NEW > General tab > Choose URLs from File. Select the file (eg I had them all pasted to a text file). Choose "No of Pages to be processed "1". I'm hoping this makes someone's life a lot easier.
