You need to know your Excel version for troubleshooting, installing add-ins, or confirming compatibility with other software. The version number and bit architecture are separate pieces of information stored in the application. This article shows you the exact steps to find your Excel version and determine if it is 32-bit or 64-bit.
Key Takeaways: How to Check Your Excel Version and Bit Architecture
- File > Account > About Excel: Opens a dialog box showing the full version number, build, and bit architecture.
- File > Account > Product Information: Displays the subscription type and update channel, which influences the version number.
- Task Manager > Details tab: Reveals if the running Excel process is 32-bit or 64-bit by checking the ‘Platform’ column.
Understanding Excel Version Numbers and Bit Architecture
Excel’s version number is a sequence like 2408 or 2312, representing the year and month of its release. Microsoft 365 subscribers receive regular updates, so this number changes. The bit architecture, either 32-bit or 64-bit, refers to how the application uses your computer’s memory and processor. A 64-bit version can use more system memory, which is beneficial for working with very large datasets and complex calculations.
You must know which bit version you have before installing certain add-ins or linking to other data sources. Most modern computers run 64-bit Windows, but Excel can still be installed as the 32-bit edition. The two versions look identical but operate differently under the hood. Checking both details is a quick process from within the Excel application itself.
Steps to Find Your Excel Version and Bit Type
The primary method uses the Account menu. For a secondary verification, you can use the Windows Task Manager.
Method 1: Using the Excel Account Menu
- Open the File tab
Launch Excel and open any workbook, even a blank one. Click the File tab in the top-left corner to go to the Backstage view. - Navigate to the Account section
In the left-hand menu, click Account. You will see your Microsoft 365 subscription information or product details for a standalone version. - Click About Excel
Look for the About Excel button, typically near the top-right of the screen. Click this button to open a detailed information dialog box. - Read the version details
The dialog box shows the full version number, such as Version 2408 (Build 17928.20152). Directly below this, you will see a line that explicitly states either “32-bit” or “64-bit.”
Method 2: Using Windows Task Manager
- Open Task Manager
Right-click the Windows taskbar and select Task Manager, or press Ctrl + Shift + Escape on your keyboard. - Switch to the Details tab
In the Task Manager window, click the Details tab to see a list of all running processes. - Locate the Excel process
Find the EXCEL.EXE process in the list. You may need to scroll or click the ‘Name’ column header to sort alphabetically. - Check the Platform column
If the Platform column is not visible, right-click any column header and select Select Columns. Check the box for Platform and click OK. The column will show “32-bit” or “64-bit” for the EXCEL.EXE process.
Common Mistakes and Limitations to Avoid
Confusing Windows Bit Version with Excel Bit Version
Your computer’s operating system architecture is separate from Excel’s. You can run 32-bit Excel on 64-bit Windows. Do not assume they match. Always check Excel’s bit type using the methods above, not your system’s About settings in Windows.
Assuming Version Number Indicates Bit Architecture
The version number, like 2408, only tells you the feature update release. It does not tell you if the installation is 32-bit or 64-bit. You must look for the specific “32-bit” or “64-bit” label in the About Excel dialog.
Missing the About Excel Button in Older Versions
In Excel 2016 or 2019, the button may be labeled About Microsoft Excel. In Excel 2013 or 2010, go to File > Help. The right panel will show the version and bit information directly, without a separate dialog button.
Excel Version and Bit Architecture: Key Differences
| Item | Version Number | Bit Architecture (32-bit vs 64-bit) |
|---|---|---|
| What it identifies | The specific feature update and build of the Excel application | How Excel is compiled to interact with the computer’s CPU and memory |
| Where to find it | File > Account > About Excel dialog box | File > Account > About Excel dialog box or Task Manager Details tab |
| Impact on use | Determines available features, formulas, and interface elements | Affects memory usage limits, performance with large files, and add-in compatibility |
| Change frequency | Changes monthly for Microsoft 365 subscribers | Only changes if you uninstall and reinstall a different edition |
| Example value | Version 2408 (Build 17928.20152) | 64-bit |
You can now accurately identify your Excel version and bit architecture using File > Account. Knowing your version number helps you search for specific update fixes, while the bit type is critical for add-in compatibility. For a related task, try checking your update channel under File > Account to see when you receive new features. An advanced tip is to press Ctrl + Alt + Shift + F12 in Excel to open the hidden Microsoft System Information window, which provides even more technical details about your installation.
