Office Excel open on a Mac

Right-click on a spreadsheet file type and click “Get Info” then select a new application in the “Open With:” section. Click “Change All…” then confirm your change to set a new default application.

Microsoft Excel works great on a Mac, but sometimes spreadsheets open in other apps like Apple Numbers instead. You can fix this by telling your Mac which app to use by default and converting incompatible files.

Make Excel the Default Spreadsheet App on Mac

To change which app a particular file opens with, you must tell macOS which application to use. You’ll need to do this for each file type you want to change. Some common file types that open in Numbers that you might want to associate with Excel instead include:

The easiest way to do this on a Mac is to right-click (or Control+click) a spreadsheet and then select “Get Info” from the context menu that appears.

Office Choose

An information window will appear, and towards the bottom you will see a section titled “Open with:” which you should expand if it isn’t already. The current default application will be listed.

Office Change the

From the drop-down box, select the application you want to use instead. In the below example, we’ve replaced Numbers with Excel.

Office Choose a new application from the drop-down box to change the default application

Finally, click “Change All…” followed by “Continue” in the dialog box that pops up.

Office Confirm your changes with

If the application you want to use (in this case, Excel) isn’t listed in the box, you can click “Other” and then navigate to the Excel app in your Applications file. Be aware that this is often a sign that your chosen file type is not compatible with the app you have chosen.

Quickly Open Spreadsheet Files in Another App

You can also access “Open With” options using the standard right-click (Control+click) context menu. The difference here is that selecting an application won’t change the default app.

This is handy if you want to open a file (like a spreadsheet) in a particular app without changing the default setting.

How to Open Numbers Files in Excel

Numbers is Apple’s spreadsheet app. Though it’s convenient, free, and pre-installed on new Mac purchases, the app lacks many of the features found in Excel. When you save a Numbers file it will be stored in Apple’s own Numbers format by default.

Unfortunately, this file cannot be opened in Excel natively. Uploading a numbers file to Google Sheets also won’t work. You can convert a Numbers file to Excel format relatively easy using the export function. If you’re not on a Mac but have an iCloud account, you can use Numbers for iCloud at to export the file instead.

If you can’t use these methods, you will need to use a file converter like CloudConvert to get the job done.

Don’t Forget About Google Sheets

Excel is a powerful spreadsheet tool that is much more powerful than Apple’s offering, while Numbers is approachable, lightweight, and free. Google Sheets is a third option that offers the best of both worlds, but you’ll be limited to using it in a browser.

Google’s spreadsheet app is packed with productivity-boosting features, and there are even some Sheets features that are lacking from Excel. To get ahead, make sure you understand the basics of using Google Sheets first.
