I wrote a tool a few years ago, and made some changes to it earlier this year. It export the data as XML, but I should be able to modify it to generate CSV instead.
You can find the current version here:
However, how do you want to handle things like line-breaks and images/attachments in Excel/Access?
I think XML might be a better choice, then you can do whatever you want with the data. My tool also detach any files attached to teh Notes documents, and extract GIF and JPG images embedded in rich text fields.
I will be out of town Friday, so if you have any questions, contact me before then. My contact info is on my website as well.
