What is a .ACCDB file?
ACCDB is the modern Microsoft Access database format. Created and opened by Microsoft Access.
- Did you know
- ACCDB replaced the older MDB format in Access 2007.
- ACCDB swapped Access’s ageing Jet engine for the newer ACE, the Access Connectivity Engine introduced with Office 2007.
- The new format added features the old MDB lacked, including multi-valued fields, attachment columns and proper AES encryption.
- What Analyser shows you
- Open Microsoft Access databases (.mdb Jet and .accdb ACE) fully in the browser: lists every user table with its columns and row count, and shows a sample of rows from each in a spreadsheet-style grid. Reads the creation date and format version. Nothing is uploaded.
- Open a .ACCDB file
- Drag a .ACCDB file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
