I am trying to load an Excel file (a telco churn example),  but whenever I view the result, the range is always unknown. May I know how to solve this issue ?

    Probably the file's metadata is not propogating correctly. I would toggle on the Sync Metadata with Real Data option in the File > Process, then run it.

    Hi @laucherhan,


    There are also other ways to inspect the result of the Read Excel Operator.

    1. Insert a Multiply Operator after Read Excel and connect one of the output ports to a result port of your process
    2. After executing the Process you can rightclick on the output port of Read Excel and then select "Show ExampleSet Results"

    In both ways you will get the output of Read Excel in the Result perspective.
