Generated spreadsheat always generates an error

[Clockwork]

Also in previous versions (incl. the non-cloud version), the generated spreadsheet (.xls), alsways generates an error, see attached. The spreadsheet can be opened after clicking 'yes'. As a remedy I always save it as an .xlsx. Spreadsheet is correct, all works fine, but the error is somewhat awkward.

Hi,

This is becuase the contents is html with .xls extension to let Excel open it.

Please see also issue#935 for references to Microsoft KB for some workarounds.

Thank you.
