My goal is to export a list of numbers into a file, with a comma between each value. Executing the following commands seems to produce a file with a new line between each entry. 

v = {1.1, 2.2, 3.3}; SetDirectory@NotebookDirectory[]; Export["v.csv", v, "csv"];

When I open the file with notepad, what I see is
1.1
2.2
3.3

What I would like to see is comma separated values, like the following:
1.1, 2.2, 3.3

Recommendations? Thanks.

Because your expression v is a vector, it's being interpreted as one line per number.

The following gives your desired result.

Export["v.csv", {v}, "csv"]
