It's rather frustrating that Microsoft don't include friendly names in their 365 Powershell commands (such as Get-MSOLAccountSku).
You can use this list to do lookups in your code and ensure that your reports are looking smart for those reading them.
👍 Will always keep up to date with the latest names
👍 Will update any issues on the same week
👍 Will not change the URL or file name, so you can download in your scripts if you wish
If you find a SKU that isn't on here, please do let me know by logging an issue.
After logging into the Microsoft Admin Portal, you can get an XML list of names for your tenant here: https://admin.microsoft.com/admin/api/tenant/accountSkus
