Hello John,
Just because the unzipped CSV file shows as an Excel file in Windows Explorer does not pose a problem.
The point is that you extract the CSV file from the ZIP file onto disk and do not open it with Excel. That is all. Because, opening it with Excel and then saving it again, destroys the format.
Once you have Extracted the CSV file, simply complete the import instructions using Diary.
Let me know if this doesn't get you going.
