Alternative Approach: Using Joins and Calculated Fields
But what do you do when you cannot pivot your data columns? You may be able to achieve the same results with joins. (Note: As of release 2022.4, Tableau does not allow joins with published data sources. If you have published data sources and need to pivot, you can achieve it using Tableau Prep.)
Depending on the number of columns you need to pivot, you can create a file with a list of numbers and use it to do a calculated join with your data. For our above scenarios, this is how we would proceed.

Join the data using a calculation as shown below:
You can now create calculated fields referencing the row numbers to assign the field names and values as desired.
