The ZIP file seems to be valid as I have been able to open it with any ZIP tool and also any other Spreadsheet solution I have. I think we need to understand first, what exactly triggers the problem. And LibreOffice does not output much information unfortunately. Also, I do not really understand why ZIP compression is different for SXSSF vs. XSSF? However, in the meantime it may be safest to set Zip64Mode.AlwaysWithCompatibility and also to print this recommendation somewhere on the website? Thanks a lot and cheers! Andreas
