There are tonnes of video tutorials and blogs which you can find online to learn about Tableau. I will be listing some of the video tutorials and blogs that helped me to learn.
However, I must also warn you that, only going through them won’t be sufficient to learn Tableau effectively. You must practice it and create workbooks on your own based on a problem statement.
And you need very good practice especially when you are aiming to crack the Tableau Certification Exam.
If you are looking for a paid structured-online-training, you can check out edureka’s Tableau course curriculum which is completely aligned to the Tableau Qualified Associate Certification exam & as well as to mastering required Tableau skills as mentioned in job postings.
