Hi Uwe,
I encountered the same issues in Russian:
1. Excel “helpfully” converted floating numbers to dates until I changed a parameter in regional settings (don’t remember which exactly at the moment: may be dot to comma for decimal separators)
2. If a paragraph/group name contains non-English characters, in Excel they’re displayed as abracadabra if CSV format is used. That’s why I added “tab delimited + TXT” option: such files are opened by the wizard so you can choose encoding, cell format, etc. Though it adds a few manual steps, it gives you full control over settings.
CSV is opened without any dialogs which is faster, but I don’t know if it’s possible to change default encoding in Excel.
Yesterday I tested it in CS3 and CS6 both on Mac and Windows fixing numerous bugs and today posted a new version – 3.1 which seems to be working as expected.
Regards,
Kasyan
