SQL Lite doesn't seem that hard to manage.
How big is the file? Do you know anything about how many tables, etc. are in the file?
If this is as you've described it should only be an hour or two to convert the file into a spreadsheet or another database format for you. I'm reluctant to say that I'll do anything without understanding it first, but I'll give your project a look this weekend if you'd like.
