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。

这是我的工作解决方案:

vbFILEOPEN = "your_utf8_file.csv"
Workbooks.OpenText Filename:=vbFILEOPEN, DataType:=xlDelimited, Semicolon:=True, Local:=True, Origin:=65001

密钥是Origin:=65001

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。

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

首先将Excel电子表格保存为Unicode文本。使用ie浏览器打开TXT文件,点击“另存为”TXT编码-选择合适的编码,例如Win Cyrillic 1251

找到了ASP的解决方案。使用POM下载UTF8格式的CSV文件:

byte[] csvBytes = Encoding.Default.GetBytes(csvString);
UTF8Encoding utf8 = new UTF8Encoding(true);
byte[] bom = utf8.GetPreamble();
var result = bom.Concat(csvBytes).ToArray();
return new FileContentResult(result, MediaTypeHeaderValue.Parse("text/csv; charset=utf-8"));

Excel是识别下载的CSV文件而不是UTF8。

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();
}
