unable to open CSV file in tableau

Hi Kane! Thanks for reaching out! Can you please provide more information so that we can try to provide specific assistance? Can you please tell us what is your operating system? Also, do you obtain an error message, or is Tableau unable to detect a *.csv file? A more detailed explanation supported by a screenshot may facilitate our understanding of the issue a lot. Thank you. Looking forward to your answer.
Best,
Martin
