What happened

When file_fFormat type is Excel, automatic type conversion is not possible. For example, when a column in Excel contains both int and string values, it always reports a type conversion error.

And there should be no empty areas in the Excel sheet, otherwise it will throw an exception, but it is normal for the sheet to have empty areas. I hope at least one configuration parameter can be provided.
