Some columns values are null after converting an Excel worksheet into any of the supported database?
Ans. This happens if the Excel Column contains intermixed data. If you have numeric values mixed with text values in the same column. Both the Jet and the ODBC Provider return the data of the majority type, but return NULL (empty) values for the minority data type. This is a known bug in the Microsoft Excel ODBC driver and OLE DB Provider. http://support.microsoft.com/default.aspx?scid=kb;EN-US;257819 There is a simple solution for this.
