summary: - Importing xls fail
+ xls import of persons fails if username is a number

If you could change the format (I know it's not easy) of "User Name" column to Default or Text, the import would succeed. I will fix this particular error, but if you will not change the format of the cells then import would fail anyway with an error "Not unicode or ascii string".

That is, the format of the cells need to be set in Excel, because by default it makes them numbers (not text), which confuses the importer. Correct? Can we convert the type on the server side as well?

Yes, the problem is that Excel (also OpenOffice Calc) changes format of a cell to number automatically. If you export and then import, no problem. But if you try to add more rows with usernames or schoolyears like 2011 then they are interpreted as numbers. But that's Bug #362014.

This bug is about a crash.
