title: Any way to flag bad lines in pandas when reading an excel file?
body: <p><code>pandas.read_csv</code> has <code>(warn, error)</code> bad lines methods. I can't see any for <code>pandas.read_excel</code>. Is there a reason? For example, if I wanted to read an excel file where a column is supposed to be a <code>datetime</code> and the <code>pandas.read_execl</code> function encounters an <code>int</code> or <code>str</code> in one/few of the rows. Do i need to handle this myself?</p>
