有没有人碰巧知道,如果有一个令牌,我可以添加到我的csv的某个字段,这样Excel就不会试图将它转换为日期?
我试图从我的应用程序中编写一个.csv文件,其中一个值碰巧看起来足够像一个日期,Excel会自动将它从文本转换为日期。我曾尝试将所有文本字段(包括看起来像日期的文本字段)放在双引号内,但没有效果。

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? .

我发现在双引号前加一个'='就能达到你想要的效果。它强制数据为文本。
如。=“2008-10-03”=“文本”
编辑(根据其他帖子):由于Jeffiekins指出的Excel 2007漏洞,应该使用Andrew提出的解决方案:"=""2008-10-03""" "
根据Jarod的解决方案和Jeffiekins提出的问题,你可以进行修改
"May 16, 2011"
to
"=""May 16, 2011"""
2018
唯一适合我的解决方案(也没有修改CSV)。
Excel 2010:
创建新工作簿 数据>从文本>选择您的CSV文件 在弹出框中选择“Delimited”单选按钮,然后点击“Next >” 分隔符复选框:只勾选“逗号”,取消勾选其他选项,然后单击“下一步>” 在“数据预览”中,滚动到最右,然后按住shift并单击最后一列(这将选中所有列)。现在在“列数据格式”中选择单选按钮“文本”,然后单击“完成”。
Excel office365:(客户端版本)
创建新工作簿 数据>从文本/CSV >选择您的CSV文件 数据类型检测>不检测
注意:Excel office365 (web版本),当我写这篇文章时,你将无法做到这一点。
(excel2007及以上版本)
如何强制excel不“检测”日期格式而不编辑源文件
:
将文件重命名为.txt 如果你不能这样做,而不是直接在excel中打开CSV文件,创建一个新的工作簿,然后转到 数据>从文本中获取外部数据>并选择您的CSV。
无论哪种方式,你都会看到导入选项,只需选择每个包含日期的列,并告诉excel格式为“文本”而不是“一般”。
无需修改您的csv文件,您可以:
将excel格式单元格选项更改为“text” 然后使用“文本导入向导”定义csv单元格。 一旦导入,删除该数据 然后粘贴为纯文本
Excel将正确格式化和分离您的CSV单元格为文本格式,忽略自动日期格式。
有点愚蠢的工作,但它比修改csv数据之前导入。安迪·贝尔德(Andy Baird)和理查德(Richard)回避了这种方法,但遗漏了几个重要步骤。
