MDB File Viewer Open an ACCDB File on a Mac

Open an ACCDB File on a Mac

ACCDB is the newer Access format. Password-protected files are where many free tools stop.

What .accdb changed

Access 2007 introduced .accdb as the replacement for .mdb. For Mac users, the important change is encryption. A password-protected .accdb file needs a tool that understands its encryption scheme.

This is why some free converters fail without a useful error. They are not rejecting the password. They cannot read the encrypted file in the first place.

Reading one on macOS

The options are much the same as they are for .mdb, but encryption rules out some of them:

Windows plus AccessWorks, including encrypted files. Costs a licence and a virtual machine.
mdbtoolsReads many .accdb files. No encrypted ones.
Web convertersUsually unencrypted only, and the file leaves your machine.
MDB File ViewerOpens both, prompts for the password, stays offline.

What the export gives you

Entering the password for an encrypted .accdb database so its tables can be read

The app first lists every table with its row and column counts. Search by name, open a table and read every row and column before you export. You can copy a cell or whole row, or export the open table directly. Choose CSV with the right separator and encoding, or put every table into one SQLite database.

The source file stays read-only. A failed or cancelled export does not change the .accdb on disk.

You can also process a folder of .accdb files in one run. Each database gets its own output folder and a summary in text, JSON and CSV.

How to open an MDB file on a Mac covers the older format and the free routes in more detail.

Questions

Can mdbtools open .accdb files?

It can read many .accdb files, but support is weaker than it is for .mdb. It cannot open an encrypted database. If the file needs a password, use another tool.

I have the password but nothing will accept it.

Many free tools do not support .accdb encryption. They fail before they can ask for the password. MDB File Viewer supports the encryption scheme and prompts when it opens the file.

What if I do not have the password?

Then the database cannot be opened. Ask the person who sent it for the password. MDB File Viewer does not try to recover or bypass one.
