How to open an .accdb file on a Mac
Microsoft Access has no Mac version, but you can open an .accdb file on a Mac with the viewer above. It runs in your browser, so nothing needs installing.
- Go to fileviewkit.com/access-database-viewer/ in any modern browser on Mac, Windows, Linux or a tablet.
- Click the drop area and pick your .accdb or .mdb file, or drag the file onto it. Enter the password if the file is encrypted.
- Select a table from the list to see its rows. Page through the data or search it.
- Download a table as CSV or Excel, or download every table as a zip of CSV files.
The other routes on a Mac are a paid viewer app (around $15–20 at the time of writing) or running Windows and Microsoft Access in a virtual machine. Both work, but they cost money and take longer to set up.
How to open an .mdb file without Microsoft Access
Drop the .mdb file onto the viewer above. It reads Access 97 to 2003 files directly, so you do not need Access or any other Microsoft software.
.mdb is the older Access format, used up to Access 2003. Newer versions of Access save .accdb instead. The viewer supports both, from Access 97 through 2019 formats, including encrypted .accdb files if you have the password. It shows tables only. Forms, reports, queries and macros are not displayed.
Convert an Access database to Excel or CSV
Open the file, choose a table and export it as CSV or Excel. To get everything at once, export all tables as a zip of CSV files.
The export happens in your browser too, so the converted file is created on your computer and not downloaded from a server. Very large tables depend on your device's memory.
Is it safe? Your file never leaves your computer
Yes. The viewer reads your file inside the browser tab and does not upload it anywhere. The page has no server that could receive it.
You do not have to take my word for it. To check:
- Open your browser's developer tools (F12, or Cmd+Option+I on a Mac) and go to the Network tab.
- Clear the list, then open your database file in the viewer.
- Look at the requests that appear. You will not see your file being sent anywhere.
You can also disconnect from the internet after the page has loaded and the viewer will still open your file. The privacy page has more detail.
How it compares
FileViewKit is the simplest option if you only need to read or export tables. If you need forms, reports or editing, you need Microsoft Access itself.
| Option | Uploads your file? | Cost | Works on Mac? | Export to Excel/CSV | Limitations |
|---|---|---|---|---|---|
| FileViewKit | No, runs in your browser | Free | Yes | Yes, CSV and Excel | Tables only (no forms or reports). Limited by browser memory. |
| Online converters that upload your file | Yes, usually | Free or paid | Yes | Usually | Your data is sent to someone else's server. Often size limits or sign-up. |
| Mac viewer apps (paid) | No | Around $15–20 at the time of writing | Yes | Usually | Must be bought and installed. Features vary by app. |
| Installing Microsoft Access (Windows only) | No | Paid licence or subscription | No | Yes | Windows only. Needs a virtual machine on a Mac. |
Frequently asked questions
Can I open an .accdb file on a Mac?
Yes. Microsoft Access does not run on macOS, but this viewer runs in any modern browser, so you can open the file on a Mac, browse its tables and export the data.
Is my file uploaded anywhere?
No. The file is read and processed inside your browser tab. You can check this yourself by watching the Network tab in your browser's developer tools while you open a file.
Which Access versions are supported?
Access 97 through 2019 formats, which covers .mdb files (Access 97 to 2003) and .accdb files (Access 2007 and later). Encrypted .accdb files open if you enter the password.
Can it open forms, reports, queries or macros?
No. The viewer shows tables only. Forms, reports, queries and macros are not displayed.
How do I get my data into Excel?
Open the file, pick a table and choose Export. You can download one table as CSV or Excel, all tables as one Excel workbook, or all tables as a zip of CSV files.
Can I open a password-protected Access database?
Yes, if you know the password. Encrypted .accdb files ask for it before opening, and the password never leaves your browser. The viewer cannot open a file without its password. Older .mdb files with a database password open directly, because that kind of password does not encrypt the data.
Does it work on a Chromebook or iPad?
Yes. It runs in the browser, so it works on a Chromebook, and on an iPad or Android tablet where you can pick a file from the Files app. Large databases need more memory than most tablets have, so a laptop is better for big files.
How big a file can it handle?
It depends on your browser and how much memory your device has. Files of a few hundred megabytes may be slow or fail on a phone or an older laptop. The viewer warns you before opening a large file.
