Unfortunately I don't believe so. There are various ways to extract roles and field data - but not that level of granularity when it comes to the role-field security.
Your best bet might be to try and copy and paste it into Excel and then do it the old fashioned way there. If you go into the each role, pick a table and open the 'Custom Access' option for fields. If you drag your mouse over the modal popup and highlight / ctrl + c copy - you can put it into Excel. Its not ideal, but gets you something.
