After connecting to OneDrive or Google Drive in Tableau Desktop, files with a capitalized extension are grayed out and cannot be selected.


  • Tableau Desktop
  • Google Drive
  • OneDrive
  • Box
  • Dropbox


Option 1

Use the equivalent native connector for the file in Tableau Desktop. For example, to connect to a Microsoft Excel file use the Microsoft Excel connector.

Option 2

Edit the name of the file and change its extension to lowercase. If the extension cannot be changed, in a File Explorer window click the 'View' tab and ensure the 'File name extensions' option is checked.


This behavior is related to a known issue with ID 940266 which is currently under investigation.
