file format does not match extension #23
Description
When opening the generated file with Excel 2010, it pops up a window saying
"The file you are tring to open is in a different format than specified by the
file extension ... Do you want to open the file now?"
When clicking yes, it works fine, however, this should really be avoided. Also,
with LibreOffice the opening of the file without any renaming is not possible.
Thank you
