In Tableau, I tried to connect data to the Tesla Sales Data excel file I had downloaded from the course but received a red exclamation mark with a note “There was a problem connecting to the data source Tesla sales data. Try editing the data source.”
Can you help with this?
I did not experience any problems connecting with the other excels I had downloaded: GDP Data and Types-of-Joins
We recommend you to try and use Data Blending instead of Joins for better results in future calculations.
