不是Excel。Windows可以识别公式、数据作为日期并自动更正。你必须更改Windows的设置。

“控制面板”(->“切换到经典视图”)->“区域和语言” 选项”->选项卡“区域选项”->“自定义…”->选项卡“数字”->和 然后根据你想要的改变符号。

它将在您的计算机上工作，如果这些设置没有更改，例如在您的客户的计算机上，他们将看到日期而不是数据。

在微软Office 2016版本中，这仍然是一个问题，这让我们这些研究基因名称的人感到不安，如MARC1、MARCH1、SEPT1等。 我发现最实用的解决方案是在R中生成一个“。csv”文件，然后将与Excel用户打开/共享:

以文本(记事本)形式打开CSV文件 复制它(ctrl+a, ctrl+c)。 粘贴到一个新的excel表格中-它将全部粘贴在一列作为长文本字符串。 选择/选择此列。 转到Data-“Text to columns…”，在打开的窗口中选择“delimited”(下一步)。检查“逗号”被标记(标记它将显示数据与下面列的分离)(下一步)，在这个窗口中，您可以选择您想要的列并将其标记为文本(而不是通用)(完成)。

对于同样的问题，我所做的是在每个csv值之前添加以下内容: “=”“” 在Excel中打开文件之前，在每个CSV值后加上双引号。以以下值为例:

012345,00198475

在Excel中打开之前，这些应该更改为:

"="""012345","="""00198475"

这样做之后，每个单元格值在Excel中都显示为公式，因此不会格式化为数字、日期等。例如，012345的值显示为:

="012345"

下面是我们在生成csv文件时使用的简单方法，它确实会稍微改变值，所以并不适用于所有应用程序:

在csv中的所有值前加一个空格

excel将从诸如“1”、“2.3”和“-2.9e4”等数字中剥离该空格，但将保留诸如“01/10/1993”这样的日期和诸如“TRUE”这样的布尔值，从而阻止它们转换为excel的内部数据类型。

它也停止双引号被zapped在读进去，所以一个简单的方法，使文本在csv中保持不变的excel即使是一些文本，如“3.1415”是用双引号包围它，并在整个字符串前加上一个空格，即(使用单引号来显示你会键入什么)“3.1415”。然后在excel中，你总是有原始的字符串，除了它被双引号包围并以空格开头，所以你需要在任何公式中考虑这些。

I know this is an old question, but the problem is not going away soon. CSV files are easy to generate from most programming languages, rather small, human-readable in a crunch with a plain text editor, and ubiquitous. The problem is not only with dates in text fields, but anything numeric also gets converted from text to numbers. A couple of examples where this is problematic: ZIP/postal codes telephone numbers government ID numbers which sometimes can start with one or more zeroes (0), which get thrown away when converted to numeric. Or the value contains characters that can be confused with mathematical operators (as in dates: /, -). Two cases that I can think of that the "prepending =" solution, as mentioned previously, might not be ideal is where the file might be imported into a program other than MS Excel (MS Word's Mail Merge function comes to mind), where human-readability might be important. My hack to work around this If one pre/appends a non-numeric and/or non-date character in the value, the value will be recognized as text and not converted. A non-printing character would be good as it will not alter the displayed value. However, the plain old space character (\s, ASCII 32) doesn't work for this as it gets chopped off by Excel and then the value still gets converted. But there are various other printing and non-printing space characters that will work well. The easiest however is to append (add after) the simple tab character (\t, ASCII 9). Benefits of this approach: Available from keyboard or with an easy-to-remember ASCII code (9), It doesn't bother the importation, Normally does not bother Mail Merge results (depending on the template layout - but normally it just adds a wide space at the end of a line). (If this is however a problem, look at other characters e.g. the zero-width space (ZWSP, Unicode U+200B) is not a big hindrance when viewing the CSV in Notepad (etc), and could be removed by find/replace in Excel (or Notepad etc). You don't need to import the CSV, but can simply double-click to open the CSV in Excel. If there's a reason you don't want to use the tab, look in an Unicode table for something else suitable. Another option might be to generate XML files, for which a certain format also is accepted for import by newer MS Excel versions, and which allows a lot more options similar to .XLS format, but I don't have experience with this. So there are various options. Depending on your requirements/application, one might be better than another. Addition It needs to be said that newer versions (2013+) of MS Excel don't open the CSV in spreadsheet format any more - one more speedbump in one's workflow making Excel less useful... At least, instructions exist for getting around it. See e.g. this Stackoverflow: How to correctly display .csv files within Excel 2013? .

我有一个类似的问题，这是解决方案，帮助我无需编辑csv文件内容:

如果你可以灵活地将文件命名为“。csv”以外的东西，你可以用“。txt”扩展名来命名它，比如“Myfile.txt”或“Myfile.csv.txt”。然后，当你在Excel中打开它(不是通过拖放，而是使用文件->打开或最近使用的文件列表)，Excel将为你提供一个“文本导入向导”。

在向导的第一页中，为文件类型选择“Delimited”。

在向导的第二页中，选择“，”作为分隔符，如果用引号括起值，还可以选择文本限定符

在第三页，分别选择每一列，并为每一列分配类型为“文本”而不是“常规”，以防止Excel弄乱你的数据。

希望这能帮助你或有类似问题的人!
