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。

这并不是准确地解决问题,但由于我偶然发现了这一点,上面的解决方案不适合我或有要求,我不能满足,这里是另一种方式添加BOM时,你可以访问vim:

vim -e -s +"set bomb|set encoding=utf-8|wq" filename.csv

其他回答

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。

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

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。

只是为了帮助有兴趣在Excel上打开文件实现这个线程的用户。

我使用了下面的向导,它对我来说工作得很好,导入了一个UTF-8文件。 不是透明的,但如果您已经有了该文件,则非常有用。

Open Microsoft Excel 2007. Click on the Data menu bar option. Click on the From Text icon. Navigate to the location of the file that you want to import. Click on the filename and then click on the Import button. The Text Import Wizard - Step 1 or 3 window will now appear on the screen. Choose the file type that best describes your data - Delimited or Fixed Width. Choose 65001: Unicode (UTF-8) from the drop-down list that appears next to File origin. Click on the Next button to display the Text Import Wizard - Step 2 or 3 window. Place a checkmark next to the delimiter that was used in the file you wish to import into Microsoft Excel 2007. The Data preview window will show you how your data will appear based on the delimiter that you chose. Click on the Next button to display the Text Import Wizard - Step 3 of 3. Choose the appropriate data format for each column of data that you want to import. You also have the option to not import one or more columns of data if you want. Click on the Finish button to finish importing your data into Microsoft Excel 2007.

如果你想让它完全自动化,点击一下,或者从一个网页自动加载到Excel中,但不能生成适当的Excel文件,那么我建议考虑SYLK格式作为替代方案。好吧,它不像CSV那么简单,但它是基于文本的,非常容易实现,它支持UTF-8没有问题。

我写了一个PHP类,接收数据并输出一个SYLK文件,该文件将通过单击文件直接在Excel中打开(或者如果您将文件写入具有正确mime类型的web页面,将自动启动Excel)。你甚至可以添加格式(如粗体,以特定的方式格式化数字等),改变列的大小,或自动调整列的文本,所有的代码可能不超过100行。

通过创建一个简单的电子表格并保存为SYLK,然后用文本编辑器读取它,就可以非常容易地对SYLK进行逆向工程。第一个块是您可以识别的标头和标准数字格式(您只需在创建的每个文件中反刍它们),然后数据只是一个X/Y坐标和一个值。
