MS-Access works very well with ODBC to MySQL.
If you have a DSN connection set up, you can import all the tables using the import from external data source. The exact menu commands vary from Access 2003 to Access 2007.
Or you can uses linked tables, which give you a live connection to MySQL tables.
In both cases you'd preserve the meta-data (column types).
I don't recommend using comma separated values or fixed width. You will waste a lot of time re-establishing the meta data (what fields are text, which are dates, etc)
