This article shows how to connect with the Semicolon delimiter text file, load its data into the Tableau desktop, and design a chart. The third image on this page shows that a Semicolon separates each column.
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. For more Data Sources >> Click Here.
If this is not the case, click the down arrow beside the Employee Semicolon Delimiter file, and choose the Text File Properties.. option.
By default, the desktop has chosen Semicolon as the Field separator. If not, by any chance, it has chosen a comma; the data looks like below. Please change the Field Separator from Comma to Semicolon from the list of available separators.
Drag Income to Columns and Education to Rows shelf. Next, add the Education dimension to the Color shelf and Income to the Label to generate the below chart. Let me add Occupation to the Rows shelf of the chart. For more Charts >> Click Here.
