But I don't know how to make this dynamically where the last date is Today.
What I need to change in dates for this ??

Oh, sorry, wrong function... should be DateTime.ToText, not DateTime.Format

Inside your url:

"https://api.exchangerate.host/timeseries?start_date=2021-01-01&end_date=2021-01-20&base..."

Insert the dynamic date

"https://api.exchangerate.host/timeseries?start_date=2021-01-01&end_date=" & DateTime.Format(DateTime.LocalNow(), "yyyy-MM-dd") & "&base..."
