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

php生成的CSV文件也有同样的问题。 当分隔符在内容开头通过“sep=,\n”定义时(当然是在BOM之后),Excel会忽略BOM。

因此,在内容的开头添加一个BOM ("\xEF\xBB\xBF"),并通过fputcsv($fh, $data_array, ";")设置分号作为分隔符;很管用。

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。

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。

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

在php中,你只需要将$bom前置到$csv_string:

$bom = sprintf( "%c%c%c", 239, 187, 191); // EF BB BF
file_put_contents( $file_name, $bom . $csv_string );

使用MS Excel 2016, php 7.2.4进行测试
