Update Microsoft Excel via Microsoft AutoUpdate

Updating your outdated version of Microsoft Excel to the latest release will resolve rendering bugs and ensure full compatibility with macOS Big Sur.

Older builds of Microsoft Excel, such as version 15.31, are not fully optimized for macOS Big Sur 11.3. Installing the latest software patches via Microsoft's built-in update tool corrects the reversed display issue.

1
Download the latest Microsoft AutoUpdate

If your current updater is broken, navigate to the official Microsoft website, download the latest Microsoft AutoUpdate (MAU) package for Mac, and run the installer.

2
Check for updates

Open Microsoft Excel. From the top menu bar, click on 'Help' and select 'Check for Updates' to launch the Microsoft AutoUpdate tool.

3
Install updates

Click the 'Update' button next to Microsoft Excel to download and install the newest version compatible with macOS Big Sur.

4
Enable automatic updates

In the Microsoft AutoUpdate window, check the box that says 'Automatically keep Microsoft Apps up to date' so future OS upgrades don't cause similar glitches.

Frequently Asked Questions

Why did my Excel screen turn upside down after updating my Mac?

This is a known rendering bug caused by software incompatibility. Older versions of Microsoft Excel (such as version 15.31) lack the necessary graphical updates to run correctly on macOS Big Sur 11.3.

Does my Office 365 subscription automatically keep Excel updated?

An active subscription provides access to the latest features, but updates are only applied automatically if you have the 'Automatically keep Microsoft Apps up to date' setting checked within the Microsoft AutoUpdate tool.

What should I do if the 'Check for Updates' button is missing or doesn't work?

If the built-in update tool fails, your Microsoft AutoUpdate application is likely outdated. You will need to download and install the standalone Microsoft AutoUpdate package directly from Microsoft's Mac support page.
