What Is An .Accdb File?
Microsoft access database file is integrated with database encoding specification by Microsoft to replace the previous MDB version with accdb database file format. Shifting with the .accdb extension, these Microsoft access database file are get integrated with support for Microsoft SharePoint Services. Another file format introduced with MS Access software, i.e ACCDE file, which get locked from displaying any VBA code associated to corresponding ACCDB file. So, this can’t be edited by the user.
The Access Database ACCDB file format replaces the older MDB format used in prior versions of Access. This includes enhancement to it like support for encryption and file attachments.
While working with this accdb file format in ms access, a similar ms access record locking information file having extension .laccdb. It automatically gets created in the same folder to prevent from accidently editing the original file. This temp file is very useful when multiple people are using the same ACCDB file simultaneously.
Benefits Of Access Accdb File Format:
Database created in access 2016/2013/2010/2007 are in .accdb file format. This format supports feature like multivalued fields, data macros, and publishing to Access Services.
One can easily convert database that were created in MS Office Access 2003/2002/2000 or 97 to .accdb file format. But the database having already in .accdb file format can’t be opened or linked by using version of Access earlier than Access 2007.
Additionally, the .accdb format doesn’t format support user level security or replication. If you want to share your database with people using Access 2003 or earlier. In order to use the replication or user level security, you must use the .mdb file format.
What Program Will Open An ACCDB File?
Accdb file can also get opened with ms access version 2007 and newer version. MS Excel import the accdb file but that data will then saved in some other spreadsheet format.

Another way to open your .accdb file without access is to use OpenOffice Base or LibreOffice Base. They both let you connect to an existing Microsoft Access 2007 database (an .ACCDB file), but the result is a file saved in the ODF file format (i.e .ODB file).
You can use this application to upload the .accdb file online and view the table without using any database software on your PC.
ACCDB MDB Explorer:
This application can also open ACCDB and MDB files, but it’s not free. So, now you can open your access .accdb file even without using the MS Access application.

How To Fix Corrupt .Accdb File?
There are two easy ways to repair corrupt ACCDB file that you can follow:
1 – With the help of In-Built Compact and Repair Database Utility
MS Access application has inbuilt Compact & Repair utility. User can use this utility whenever they encounter any type of corruption or errors. This tool can easily fix most of the corruption and various errors of your inaccessible MS Access file. However, whenever you are looking to use compact and repair utility you must take backup of your file.
2- Decompile Microsoft Access VBA code
When VBA modules get complied in Access, the complied code is very much dependent on the VBA p-code parser library. There are few types of this library which can lead to corruption if the compiled code is run on various machines with different versions of this library installed.
Microsoft added a command line witch to access that allows removing all complied VBA codes from an Access database, leaving only the non-complied source code in place. You can try the command line switch if you can gain access into your database but strange error messages will appear during this execution of VBA module/class code.
To run the decompile option from Access just open access with a command line option of ‘/decompile’, for example, run the following from the command line:
C:\Program Files\Microsoft Office\Office\MsAccess.exe /decompile C:\DatabasePath\FileName.mdb
You need to change the path shown above for MsAccess.exe if you installed it to different location. After the completion of the decompile procedure, you should close access and then re-open it compile all modules again.
