So when I saved my csv files they show up in my onedrive or download files as csv or xlsx type but it won't open as excel
<<
What do you mean by "it won't open as excel"? If everything is configured correctly on your system in terms of the default apps associated with various file types, a CSV and .xlsx file will be opened by Excel by default

When I try to change how to open it up, I don't see excel as an option

So if you double-click on the file, are you saying that it's not opened by Excel. If yes, what happens?

Below is a screenshot of how I keep seeing these files. I turned off Microsoft edge from my control panel to see if that would help but it did not.

Not clear as to what is wrong with the screenshot you provided. All that's missing is that you don't have file extensions but the file properties clearly shows the particular file to be a CSV file and you arrive to that by right-clicking on the file and selecting <Properties>
Am really sorry for having a problem following this but not at all clear as to the exact problem especially give what appears to be the Win10 Mail app you are using to send the message
