Values in a Boolean column in OData may be imported incorrectly as Null in Tableau Desktop.


  • Tableau Desktop 2020.2 and newer
  • Odata


As possible workarounds, try the following options:

Option 1

Connect to OData data source using Tableau Desktop 2020.1 instead.

Option 2

  1. In the Data pane, change the data type of the Boolean fields to String: Click the icon to the left of the field name, and then choose String from the drop-down list.
  2. Refresh the extract: Right-click the data source and select Extract > Refresh.
  3. Create Boolean calculated fields based on the String fields.
