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。


当前回答

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。

简单的vba宏用于打开utf-8文本和csv文件

Sub OpenTextFile()

   filetoopen = Application.GetOpenFilename("Text Files (*.txt;*.csv), *.txt;*.csv")
   If filetoopen = Null Or filetoopen = Empty Then Exit Sub

   Workbooks.OpenText Filename:=filetoopen, _
   Origin:=65001, DataType:=xlDelimited, Comma:=True

End Sub

原点:=65001为UTF-8。 逗号:对于按列分布的.csv文件为True

保存在个人。XLSB使它始终可用。 个性化excel工具栏添加一个宏调用按钮,并从那里打开文件。 您可以添加更多的格式到宏,如列自动拟合,对齐等。

我们使用了以下方法:

转换CSV到UTF-16 LE 在文件开头插入BOM 使用制表符作为字段分隔符

这是一个老问题,但我刚刚遇到过类似的问题,解决方案可能会帮助其他人:

同样的问题是,将CSV文本数据写入文件,然后在Excel中打开生成的. CSV,将所有文本转移到单个列中。在阅读了上面的答案后,我尝试了下面的答案,这似乎可以解决问题。

在创建StreamWriter时应用UTF-8编码。就是这样。

例子:

using (StreamWriter output = new StreamWriter(outputFileName, false, Encoding.UTF8, 2 << 22)) {
   /* ... do stuff .... */
   output.Close();
}

下载并安装LibreOffice Calc 在LibreOffice Calc中打开您选择的csv文件 谢天谢地,一个导入文本向导出现了…… ...选择分隔符和字符编码选项 在Calc中选择结果数据并复制粘贴到Excel中

一个真正令人惊叹的答案列表,但由于还缺少一个非常好的答案,我在这里提到它:打开谷歌表的csv文件,并将其保存到本地计算机作为excel文件。

与微软相比,谷歌已经成功支持UTF-8 csv文件,所以它只是在那里打开文件。导出到excel格式也可以。因此,尽管这可能不是所有人的首选解决方案,但它是非常安全的,点击次数也不像听起来那么多,特别是当您已经登录到谷歌时。
