For more information, see Clean Data from Excel, CSV, PDF and Google Sheets with Data Interpreter. Data Interpreter can detect sub-tables that you can use and remove unique formatting that might cause problems later on in your analysis. If Tableau detects that it can help optimise your data source for analysis, it prompts you to use Data Interpreter. If field names are not included, Tableau generates them automatically. If so, these names will become the field names in Tableau. To change the table options, on the canvas, click the table drop-down arrow and then specify whether the data includes field names in the first row.

For more information about upgrading data sources, see Upgrade Data Sources. Either remove the columns, modify them to fit within 254 characters prior to connecting in Tableau Desktop, or upgrade the Excel data source. Also, you cannot use the legacy connection to connect to this data. Note: If the Excel file contains columns that are more than 254 characters wide, Tableau Desktop cannot use these fields for workbooks that were created before Tableau Desktop 8.2. The following is an example of a Microsoft Excel data source. Note: Tableau does not support pivot tables in Excel. You can connect to multiple Excel workbooks at the same time, as long as each connection in the data source has a unique name. When you connect to a named range or Excel table in Tableau, an icon appears next to the sheet in the Data Source page, as shown below. Similar to named ranges, you can create an Excel table in Excel by selecting a range of cells, and then selecting Insert > Table. You create named ranges in Excel by selecting a range of cells and then selecting Define Name on the Formulas tab. Both the named range and Excel table function as a table in Tableau. You can also connect to a named range or an Excel table (also known as an Excel list) in the same way as you connect to a worksheet. For more information, see Connect to a Custom SQL Query. Use custom SQL to connect to a specific query rather than the entire data source. If your Excel file has one table, click the sheet tab to start your analysis. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to. (Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau.

On the Data Source page, do the following: See the Legacy Connection Alternatives document in Tableau Community for alternatives to using the legacy connection. NOTE: Beginning with Tableau 2020.2, legacy Excel and Text connections are no longer supported. Select the Excel workbook you want to connect to, and then click Open.
