Preparing Forex Data for Tableau

I am pretty new to Knime I understand the basics of it as how it operates. However, I feel a bit lost because I am using Python script to retrieve forex data from MetaTrader5 to create a dataframe with the date, currency symbols and a formula for the adjusted close price. I have been able to successfully run it in VS Code as well as Google Colab. The problem is that if I save it as a csv and open it in Tableau it would give me issues. This is why I need a mentor or some type of one on one to get this project working. I have looked at all types of YouTube tutorials however Knime has updated their software so I’m just going through the basic training in Knime. I hope there’s some type of training on the Python scripting node with software updates.
