<p>Is there a canonical csv parser in golang with a wide variety of configurable settings (similar to pandas.read_csv <a href="https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_csv.html" rel="nofollow">https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_csv.html</a>)? It seems like the encoding/csv lib covers some of variations in csv format, but there are other options that I think are pretty standard (header/footer lines for example)</p>
<hr/>**评论：**<br/><br/>shovelpost: <pre><p>The standard library CSV package implements RFC 4180. For variations and other stuff not included in the spec you'll either have to do <a href="https://github.com/golang/go/issues/12755#issuecomment-150670079" rel="nofollow">some manual work</a> yourself or look for a 3rd party CSV package like <a href="https://github.com/gocarina/gocsv" rel="nofollow">this</a>.</p></pre>unimportant1234567: <pre><p>I just use this:

<p>the commented out line is if you have CR+LF line endings.</p>
