The database your old system left behind
For two decades, Microsoft Access was where small-business data lived: the customer list, the inventory, the billing records, the clinic’s patient index. The applications are long retired, but the .mdb and .accdb files survive on backup drives and old servers - and opening one today means buying Access or finding something that reads the format.
This reads it. Every user table is exported to its own CSV and the set is delivered as one ZIP: table names preserved, dates in ISO form, text decoded to UTF-8 so Hebrew, Cyrillic and accented names come through exactly as entered. Queries, forms and macros are ignored by design - the tables are the data.
Old databases are still personal data
A forgotten Access file is usually a complete record of real people - which is precisely why it should not be uploaded to a converter that parks files on disk. Here the database is parsed inside a sandboxed process with no network access, entirely in memory, on a server with swap disabled. Nothing is written to disk, nothing is logged about the contents, and the file is deleted the moment your download is delivered.
The output is hardened too: embedded OLE objects are stripped instead of dumped as mojibake, and any cell Excel could mistake for a formula is neutralised - the standard spreadsheet-injection guard across this site.
Where to take it from here
Prefer a single workbook over a ZIP of files? Access to Excel puts each table on its own sheet. To make the data queryable again, feed a table through CSV to SQLite or CSV to SQL. Migrating a whole legacy system? The CRM & ERP exports guide maps every format on the way out, and this conversion is on the API at /api/convert/mdb-to-csv.

A more private way to convert MDB files
Plenty of sites convert MDB files. Very few promise never to keep them - PrivConvert does, and backs it up with how the service is built.
We never keep a copy. Once your CSV is delivered, both the original and the result are gone - there is nothing left to leak or misuse.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
Files are processed in volatile memory (RAM) and purged the instant your download is ready - nothing is ever written to disk, cached or backed up.
