convert advantage ADT database to CSV or MDB

I need these 5 .adt files into a CSV file, or TXT file or Access MDB or SQL Lite. Your work will either be a one-time conversion for these 5 files, or a working solution that I can use again in the future. It would always be the same 5 tables. The latter solution has my preference, so if you have some small executable, that would be perfect. If there is any online website that can do this, this is also OK for me.
