But not for me, irritatingly (mine is up to date, and I can open .xlsx files through LibreOffice):

gretl version 2020b-git
Current session: 2020-03-22 09:38

? string site = "https://www.ecdc.europa.eu/sites/default/files/documents/"
Generated string site
? string fname = "COVID-19-geographic-distribution-worldwide-2020-03-21.xlsx"
Generated string fname
? string URL = site ~ fname
Generated string URL
? open @URL --quiet
gretl_unzip: /home/clive/.gretl/COVID-19-geographic-distribution-worldwide-2020-03-21.xlsx: zip error: Zip file structure invalid

Error executing script: halting
> open @URL --quiet

In the end, I saved and renamed the file manually and opened it through -gretl- in the usual way. But it would be nice if the other way worked.

I guess this should work ok:

<hansl>
string site = "https://www.ecdc.europa.eu/sites/default/files/documents/"
string fname = "COVID-19-geographic-disbtribution-worldwide-2020-03-21.xlsx"
string URL = site ~ fname
open @URL --quiet
setobs Countriesandterritories DateRep --panel-vars
</hansl>
