You can make certain connections very quickly. These options will allow you to begin analyzing more quickly:

• Paste data from the clipboard. If you have copied data from a spreadsheet, a table on a webpage, or a text file, you can often paste the data directly into Tableau. This can be done using Ctrl + V, or Data | Paste Data from the menu. The data will be stored as a file and you will be alerted to its location when you save the workbook.
• Select File | Open from the menu. This will allow you to open any data file that Tableau supports, such as text files, Excel files, Access files (not available on macOS), spatial files, statistical files, JSON, and even offline cube (.cub) files.
• Drag and drop a file from Windows Explorer or Finder onto the Tableau workspace. Any valid file-based data source can be dropped onto the Tableau workspace, or even the Tableau shortcut on your desktop or taskbar.
• Duplicate an existing connection. You can duplicate an existing data source connection by right-clicking and selecting Duplicate.
