Does as advertised, and does it well.
Ive used several Access converters before, some CLI and some GUI, and while others have more bells & whistles, they also would crash or be unable to extract data from certain Access dbs due to unusual table structures, large size, etc. MDB viewer flawlessly handled all of them - over 100 Access dbs, each with 100,000+ records and file sizes in the hundreds of MBs, and exported them as SQLite compatible SQL; on a high-end 2008 Mac Pro, it took under 9 minutes to generate 2.78 GB of SQL from a 700 MB Access db.
One wish - make it Applescriptable so I can automate it the next time I have to do work like this! :-)
