Problem with dumping data into database using import excel smart service

I am having same field names in database table as well as in my excel file. Also configured it in data store correctly. But while using import excel smart service to dump data, even after providing same table name as database table, data source name- "jdbc/Appian", and excel document having similar fields, there is no error populating but I cannot see my data in my database, nothing's happing there.
