做到这一点的唯一“简单方法”如下。首先，要意识到Excel .csv文件中显示的内容和隐藏的内容之间是有区别的。

Open an Excel file where you have the info (.xls, .xlsx) In Excel, choose "CSV (Comma Delimited) (*.csv) as the file type and save as that type. In NOTEPAD (found under "Programs" and then Accessories in Start menu), open the saved .csv file in Notepad Then choose -> Save As... and at the bottom of the "save as" box, there is a select box labelled as "Encoding". Select UTF-8 (do NOT use ANSI or you lose all accents etc). After selecting UTF-8, then save the file to a slightly different file name from the original.

该文件采用UTF-8格式，保留所有字符和重音，可以导入，例如，MySQL和其他数据库程序。

Easy way to do it: download open office (here), load the spreadsheet and open the excel file (.xls or .xlsx). Then just save it as a text CSV file and a window opens asking to keep the current format or to save as a .ODF format. select "keep the current format" and in the new window select the option that works better for you, according with the language that your file is been written on. For Spanish language select Western Europe (Windows-1252/ WinLatin 1) and the file works just fine. If you select Unicode (UTF-8), it is not going to work with the spanish characters.

您可以将excel保存为unicode文本，它是制表符分隔的。

“nevets1219”是正确的谷歌文档，然而，如果你只是“导入”文件，它通常不会将其转换为UTF-8。

但是如果您将CSV导入到现有的谷歌电子表格中，它会转换为UTF-8。

下面是一个食谱:

在主文档(或驱动器)屏幕上点击“创建”按钮并选择“电子表格” 在“文件”菜单中选择“导入” 按“选择档案” 选择“替换电子表格” 选择要用作分隔符的字符 点击“导入” 从“文件”菜单选择“下载为”-> CSV(当前文件)

生成的文件将是UTF-8格式的

我知道这是一个老问题，但我碰巧在与OP同样的问题作斗争时遇到了这个问题。

没有发现任何提供的解决方案是可行的选择，我开始探索是否有一种方法可以只使用Excel来做到这一点。

幸运的是，我发现丢失字符的问题只发生(在我的情况下)从xlsx格式保存到csv格式。我尝试先将xlsx文件保存到xls，然后再保存到csv。它确实起作用了。

请试一试，看看对你是否有用。祝你好运。
