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.

我发现OpenOffice的电子表格应用程序Calc非常擅长处理CSV数据。

在“另存为…”对话框中，单击“格式选项”可获得CSV的不同编码。LibreOffice的工作原理与AFAIK相同。

另一个解决方案是用winword打开文件，并将其另存为txt，然后用excel重新打开，它将工作ISA

Excel通常将csv文件保存为ANSI编码，而不是utf8编码。

更正文件的一个选项是使用Notepad或notepad++:

使用Notepad或notepad++打开.csv文件。 复制内容到你的电脑剪贴板。 从文件中删除内容。 将文件的编码更改为utf8。 将剪贴板上的内容粘贴回来。 保存文件。
