This page is woefully out of date. MDB Tools has moved to GitHub. Please update your links to use this address:

The rest of this page remains for historical interest.

The MDB Tools project is a effort to document the MDB file format used in Microsoft's Access database package, and to provide a set of tools and applications to make that data available on other platforms.

Specifically, MDB Tools includes programs to export schema and data to other databases such as MySQL, Oracle, Sybase, PostgreSQL, and others.

Also included is a SQL engine for performing simple SQL queries. The 0.5 release includes an updated GUI interface (screenshot is available here). A sparse but functional ODBC driver is included as well.

MDB Tools currently has read-only support for Access 97 (Jet 3) and Access 2000/2002 (Jet 4) formats. Write support is currently being worked on and the first cut is expected to be included in the 0.6 release.

For more information check our FAQ and our Installation Guide. Also see our SourceForge Page for forums, bugtracking, CVS, et al.
