I'm using Tableau under a student licence, and I can save in .twb and .twbx formats.
When I graduate I expect I'll take a monthly Tableau personal licence. According to the information at Tableau Desktop | Tableau Software , .twb and .twbx are not listed among the file types that the personal licence version can read.
Will I be able to read the learnings that I have saved from my student days when I hold a Tableau personal licence?
.twb and .twbx are not data sources. They are Tableau workbooks. So, the answer is yes, you will be able to open and read them using the personal license.
