Probably the easiest & quickest & best way to do this would be to use Make's XML tools to convert your CSV file into an XML file.
Simply drop your CSV file into a cloud drive folder (such as Google Drive), and then your Make automation would be setup to automatically parse the CSV file using its CSV tools, convert it into an XML file, and then upload the final XML file to a cloud drive.
If you've never used Make before, it might take you a few hours to learn how to use it, but take a look at the screenshot below to see how I set this up in Make.
In the screenshot below, you will see the chain of modules that you would need to setup in Make.
Make provides some basic XML instructions here.
And I show how to monitor a cloud drive for CSV files in this Airtable podcast.
I've also assembled some Make training resources in this thread. And Make even created an entire Make Training Academy here.
