For some reason when importing some floating numbers, Mathematica does not interpret them correctly. For example this spreadsheet:

And this code:

Import["https://docs.google.com/spreadsheets/d/\
1zddNRubvfaRx1ySDXFbqGl5ohPdjI9Eld1Fr3ERWliA/export?format=csv", \
"CSV", CharacterEncoding -> "UTF8"]
{{"2,15"}, {"2,45"}, {"1,88"}, {"2,35"}, {"11,35"}, {"2,08"}, {2272}, \
{"1,83"}, {"1,91"}, {"1,9"}}


See how 2,272 is incorrectly imported as 2272. Why is this the case, and how can I fix it?

You need to set the "NumberPoint" option explicitly if you're importing numbers with decimal commas:

ImportString["2,15
2,45
1,88
2,35
11,35
2,08
2,272
1,83
1,91
1,9", "List", "NumberPoint" -> ","]
{2.15, 2.45, 1.88, 2.35, 11.35, 2.08, 2.272, 1.83, 1.91, 1.9}
