I'm developing a part of an application that's responsible for exporting some data into CSV files. The application always uses UTF-8 because of its multilingual nature at all levels. But opening such CSV files (containing e.g. diacritics, cyrillic letters, Greek letters) in Excel does not achieve the expected results showing something like Г„/Г¤, Г–/Г¶. And I don't know how to force Excel understand that the open CSV file is encoded in UTF-8. I also tried specifying UTF-8 BOM EF BB BF, but Excel ignores that.

有什么解决办法吗?

附注:哪些工具可能像Excel一样?


更新

I have to say that I've confused the community with the formulation of the question. When I was asking this question, I asked for a way of opening a UTF-8 CSV file in Excel without any problems for a user, in a fluent and transparent way. However, I used a wrong formulation asking for doing it automatically. That is very confusing and it clashes with VBA macro automation. There are two answers for this questions that I appreciate the most: the very first answer by Alex https://stackoverflow.com/a/6002338/166589, and I've accepted this answer; and the second one by Mark https://stackoverflow.com/a/6488070/166589 that have appeared a little later. From the usability point of view, Excel seemed to have lack of a good user-friendly UTF-8 CSV support, so I consider both answers are correct, and I have accepted Alex's answer first because it really stated that Excel was not able to do that transparently. That is what I confused with automatically here. Mark's answer promotes a more complicated way for more advanced users to achieve the expected result. Both answers are great, but Alex's one fits my not clearly specified question a little better.

在最后一次编辑5个月后,我注意到Alex的答案不知为何消失了。我真的希望这不是一个技术问题,我希望现在不再有关于哪个答案更好的讨论。所以我认为马克的答案是最好的。

我正在从一个简单的c#应用程序生成csv文件,也遇到了同样的问题。我的解决方案是确保文件是用UTF8编码编写的,如下所示:

// Use UTF8 encoding so that Excel is ok with accents and such.
using (StreamWriter writer = new StreamWriter(path, false, Encoding.UTF8))
{
    SaveCSV(writer);
}

我最初有以下代码,其中口音在notepad++中看起来很好,但在Excel中被破坏:

using (StreamWriter writer = new StreamWriter(path))
{
    SaveCSV(writer);
}

你的里程可能会有所不同——我使用的是。net 4和Office 365中的Excel。

正如我在http://thinkinginsoftware.blogspot.com/2017/12/correctly-generate-csv-that-excel-can.html:上发表的

告诉负责生成CSV的软件开发人员纠正它。作为一个快速的解决方法,你可以使用gsed在字符串的开头插入UTF-8 BOM:

gsed -i '1s/^\(\xef\xbb\xbf\)\?/\xef\xbb\xbf/' file.csv

如果UTF-4 BOM不存在,该命令将插入。因此这是一个幂等命令。现在您应该能够双击该文件并在Excel中打开它。

您可以转换。csv文件到UTF-8与BOM通过notepad++:

在notepad++中打开文件。 进入“编码→转换为UTF-8-BOM”菜单。 进入菜单文件→保存。 关闭记事本+ +。 在Excel中打开文件。

在Microsoft Excel 2013 (15.0.5093.1000) MSO(15.0.5101.1000) 64位中工作,来自Microsoft Office Professional Plus 2013在Windows 8.1上,非unicode程序的区域设置为“德语(德国)”。

几天前我遇到了同样的问题,找不到任何解决方案,因为我不能使用从csv导入功能,因为它使所有内容都被样式化为字符串。

我的解决方案是首先用notpad++打开文件,并将编码更改为ASCII。 然后在excel中打开文件,它就像预期的那样工作了。
