Where is usually debug file located? I am currently importing Excel file, and getting an error. It doesn't have a specific informations.

Thanks,

No log file created, sorry.

However there should be a table ending on "_ImportErrors" if your problem is data related.

You could try saving the excel file as a CSV and see what happens when you import. Provided you are trying import to access, most of the errors I ever get on import are related to field datatype issues.
