I'd say it all depends on what you need/want to do with those files :
CSV has one advantage : it can be imported to Excel and such applications -- which might be usefull in some situations, to do reporting to a superior, for instance
JSON is readable in many languages, including Javascript ; but not easy to read by a human being ; and harder to modify "by hand"
And YAML is quite easy to read ; not hard to modify by hand ; but not sure about the availability of libraries to read it in several languages.
If you are in none of these situations :
must be readable
by a human being
in several programming languages
easy to modify
same notes
Then I guess all three formats will be OK ^^
Without knowing more, I would go with either CSV (for the import to Excel stuff), or JSON (for the portability reason).

我想 CSV 会更容易，因为以下几个原因：
当然，我选择为每个日志项创建一个单独的 JSON 对象并将每个日志项放在单独的行上，这不是问题。
I guess CSV would be easier because of a couple of reasons:
Of course, I you choose to create a separate JSON object for each log item and put each on a separate line, this isn't an issue.
