This article shows how to connect with the Semicolon delimiter text file, load its data into the tableau desktop, and design a chart.

Connect Tableau to a Semicolon Delimiter Text File
Clicking on the text file option will open the window to choose the Semicolon delimited file.
As you can see, the Tableau desktop loaded the file and automatically separated the columns using a Semicolon delimiter.
If it is not the case, choose the Text File Properties.. option.
