Description
When a Microsoft Excel file is introspected in TIBCO Data Virtualization using a Microsoft Excel (non-ODBC) data source then the data types are introspected as a VARCHAR.
This is because, when an Excel file is introspected into TIBCO Data Virtualization then the " Introspect with Formatted Display Values instead of Actual Values" option is selected by default.
If "Introspect with Formatted Display Values instead of Actual Values" is selected (which it is by default), the columns will be introspected as VARCHAR and the values will be displayed in TIBCO Data Virtualization as they are displayed in Excel (WYSIWYG).
