是否可以强制Excel自动识别UTF-8 CSV文件?

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?

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

其他回答

现在是2022年3月，似乎我们不能同时使用BOM和sep=…线。添加sep=\t或类似的，使Excel忽略BOM。

使用分号似乎是Excel的默认理解，在这种情况下，我们可以跳过sep=…这样就行了。

是的，这是可能的。当写入流创建csv时，要做的第一件事是:

myStream.Write(Encoding.UTF8.GetPreamble(), 0, Encoding.UTF8.GetPreamble().Length)

我尝试了我能在这个帖子上找到的一切，类似的，没有什么是完全有效的。然而，导入到谷歌表和简单地下载为csv工作就像一个魅力。如果你到了我的挫败点，可以试试。

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。

office 365的工作解决方案

保存在UTF-16(无LE, BE) 使用分离器\t

PHP代码

$header = ['číslo', 'vytvořeno', 'ěščřžýáíé'];
$fileName = 'excel365.csv';
$fp = fopen($fileName, 'w');
fputcsv($fp, $header, "\t");
fclose($fp);

$handle = fopen($fileName, "r");
$contents = fread($handle, filesize($fileName));
$contents = iconv('UTF-8', 'UTF-16', $contents);
fclose($handle);

$handle = fopen($fileName, "w");
fwrite($handle, $contents);
fclose($handle);
