Do you support spreadsheet programs other than Excel?

Why don't I see any thumbnails in Excel?
Have you exported the thumbnails? This is done separately from exporting the text.
The most-recent version of Excel for Mac fails to import thumbnails from HTML. This appears to be a bug in Excel.
Have you chosen HTML export? Thumbnails are only available in HTML export - comma-separated text can't include images.
