          Parameters
          ----------
          convert_dates : boolean, default True
              If True, convert to date where possible. If 'coerce', force
              conversion, with unconvertible values becoming NaT.
          convert_numeric : boolean, default False
              If True, attempt to coerce to numbers (including strings), with
              unconvertible values becoming NaN.
          convert_timedeltas : boolean, default True
              If True, convert to timedelta where possible. If 'coerce', force
              conversion, with unconvertible values becoming NaT.
          copy : boolean, default True
              If True, return a copy even if no copy is necessary (e.g. no
              conversion was done). Note: This is meant for internal use, and
              should not be confused with inplace.
  
          Returns
          -------
          converted : same as input object
