Welcome to the exciting world of MDB Tools! MDB Tools is a set of programs to help you extract data from Microsoft Access files in various settings. See the NEWS file for information about the latest release.


The major pieces of MDB Tools are:


The core library that allows access to MDB files programatically.


Builds on libmdb to provide a SQL engine (aka Jet)


Provides command line utilities, including:

Command Description
mdb-ver Prints the version (JET 3 or 4) of an mdb file.
mdb-schema Prints DDL for the specified table.
mdb-export Export table to CSV or SQL formats.
mdb-json Export table to JSON format.
mdb-tables A simple dump of table names to be used with shell scripts.
mdb-count A simple count of number of rows in a table, to be used in shell scripts and ETL pipelines.
mdb-sql A simple SQL engine (also used by ODBC and gmdb).
mdb-queries List and print queries stored in the database.
prcat Prints the catalog table from an mdb file.
prkkd Dump of information about design view data given the offset to it.
prtable Dump of a table definition.
prdata Dump of the data given a table name.
prole Dump of ole columns given a table name and sargs.
mdb-hexdump (in src/extras) Simple hex dump utility that I've been using to look at mdb files.
mdb-array Export data in an MDB database table to a C array.*
mdb-header Generates a C header to be used in exporting mdb data to a C prog.*
mdb-parsecsv Generates a C program given a CSV file made with mdb-export.*

* Deprecated


An ODBC driver for use with unixODBC or iODBC driver manager. Allows one to use MDB files with PHP for example.


The Gnome MDB File Viewer and debugger. Alpha quality, moved to mdbtools/gmdb2.


Files in libmdb, libmdbsql, and libmdbodbc are licensed under LGPL and the utilities and gui program are under the GPL, see COPYING.LIB and COPYING files respectively.


First, you must have reasonably current installations of:

If you want to build the SQL engine, you'll need bison (version >= 3.0) or byacc, and flex.

If you want to build the ODBC driver, you'll need unixodbc-dev (version 2.2.10 or above) or iodbc.

If you want to build man pages, you'll need GNU awk.


Latest version is available at


apt install mdbtools


brew install mdbtools

From source

If you have cloned the Git repository, you will first need to generate the configure file (skip this step if you have downloaded a formal release):

$ autoreconf -i -f


$ ./configure

OR for a complete install (requires bison, flex, and unixODBC):

$ ./configure --with-unixodbc=/usr/local

By default, MDB Tools is linked against the copy of GLib returned by pkg-config. You can point to a different GLib installation using the GLIB_CFLAGS and GLIB_LIBS enivornment variables. Or, you can disable GLib entirely with the --disable-glib flag, in which case MDB Tools will use an internal implementation of GLib's functions.

configure can be passed any of the following flags to turn on other capabilities. Note that the options --with-unixodbc and --with-iodbc are mutually exclusive.

--with-unixodbc  specifies the location of the unixODBC driver manager and 
                 causes the unixODBC driver to be built.
--with-iodbc     specifies the location of the iODBC driver manager and 
                 causes the iODBC driver to be built.

A list of general options is available in the INSTALL file, and configure --help will give you the list of mdbtools specific options.

$ make

Once MDB Tools has been compiled, libmdb.[so|a] will be in the src/libmdb directory and the utility programs will be in the src/util directory.

You can then install (to /usr/local by default) by running the following as root:

$ make install

Some systems will also need the ld cache to be updated after installation; You can do that running:

$ ldconfig
