Can I export pages, edit and import again?

Hi – I have searched the forums and haven’t come across an answer. Perhaps I’m looking for the wrong words, but this is what I need to do.

I have a site with nearly 800 pages. They need to be edited – the template and the body text. I was looking for a plugin that would let me export the pages in a CSV or similar file, edit them, and then import them back.

Obviously I could do part of this with the bulk edit feature, but not the HTML. Another good choice might be an advanced find and replace plugin.

Thanks in advance for the help!
