Before doing something as drastic as replacing a MacBook Air’s SSD, it pays to confirm the drive is actually damaged and unrepairable. Run Apple’s Disk Utility for a start. If that fails, try. I've been using Excel on a Mac for several years (actually since 1984 when it was called MS Chart) and find it very capable as a replacement for Excel on a Windows computer. That said, another way to go would be to run Windows via Boot Camp (or Fusion or Parallels) and use MS Office there if you have other apps that require Windows.
With most Office 365 plans, you’re able to download and install full versions of Microsoft Office programs like Word, Excel, and PowerPoint on your PC, Mac, or mobile device. All of these desktop applications connect to the cloud just like the online (web app) versions, which means you can do your work with or without an internet connection and all your data will automatically sync the next time you connect.
Follow the steps in this video to download Office programs to your PC and get started using the installed versions of Word, Excel, PowerPoint, Lync, and Outlook 2013 or 2016.
How do I know if my plan includes Office 2013/2016 programs?
As you can see in the video, you’ll see the Office programs you have available on your Office installation page, which you can access after signing into Office 365. The list of Office applications varies depending on your plan and operating system.

If you don’t see any available installs, contact your IT admin. If you are the Office 365 admin for your organization, you’ll need to assign licenses for users to download the latest version of Office. Check out this Microsoft help article if you’re a small business account admin, or this help article if your org has a Midsize or Enterprise plan.
I don’t need PowerPoint, do I have to install it?
In Office 365, all the Office programs are packaged together for download and installation, so there’s no way to exclude an individual application.
How do I find my product key?
Office 365 for business doesn’t utilize product keys like other versions of Office–you simply need to sign in with your user ID to install, deactivate an installation, or reinstall.
If you are using a different version of Office and need your product key, visit this Microsoft help article.

Install fonts
Double-click the font in the Finder, then click Install Font in the font preview window that opens. After your Mac validates the font and opens the Font Book app, the font is installed and available for use.
You can use Font Book preferences to set the default install location, which determines whether the fonts you add are available to other user accounts on your Mac.
Fonts that appear dimmed in Font Book are either disabled ('Off'), or are additional fonts available for download from Apple. To download the font, select it and choose Edit > Download.
Disable fonts
You can disable any font that isn't required by your Mac. Select the font in Font Book, then choose Edit > Disable. The font remains installed, but no longer appears in the font menus of your apps. Fonts that are disabled show ”Off” next to the font name in Font Book.
Remove fonts
You can remove any font that isn't required by your Mac. Select the font in Font Book, then choose File > Remove. Font Book moves the font to the Trash.
