How to display data on my website from a csv file which was uploaded by a user?

Hi! I need to display on my website the data from a CSV file uploaded by a user. I have set up a “choose file” field with an upload button and that button uploads to the site’s file system. However, I do not know how to get the data from that CSV file and display it on the page. The user uploads a file and then it is “visualized” to him.

For the “upload button” I used code from here: https://support.wix.com/en/article/wix-code-using-the-upload-button-with-code

Thank you for your time and suggestions!
