Unable to Extract Data from Excel using AI Document Center in Appian

Certified Associate Developer

Hi Appian Community,
I am using AI Document Center in Appian to Extract an Excel file. The extraction runs successfully, but the Extracted Value column is empty. Only the field labels are displayed (e.g., S.No, Name, Age, Location, Role, Salary, Time, Status), but no actual data is populated and also not able see the preview of excel 

Any guidance or best practices would be appreciated.
