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。

使用谷歌驱动器(如果你在Mac上,也可以使用Numbers)的解决方案:
在Excel中打开数据 将数据错误的列的格式设置为文本(format > Cells > Number > Text) 将.csv文件加载到谷歌Drive,并使用谷歌Sheets打开它 复制出错的列 将列作为文本粘贴到Excel中(编辑>粘贴特殊>文本)
或者,如果你在Mac上进行第3步,你可以在Numbers中打开数据。

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? .
嗨,我也有同样的问题,
我写这个vbscipt来创建另一个CSV文件。新的CSV文件将在每个字段的字体中有一个空格,因此excel将把它理解为文本。
所以你用下面的代码创建了一个。vbs文件(例如Modify_CSV.vbs),保存并关闭它。将原始文件拖放到vbscript文件中。它将在相同的位置创建一个文件名为“SPACE_ADDED”的新文件。
Set objArgs = WScript.Arguments
Set objFso = createobject("scripting.filesystemobject")
dim objTextFile
dim arrStr ' an array to hold the text content
dim sLine ' holding text to write to new file
'Looping through all dropped file
For t = 0 to objArgs.Count - 1
' Input Path
inPath = objFso.GetFile(wscript.arguments.item(t))
' OutPut Path
outPath = replace(inPath, objFso.GetFileName(inPath), left(objFso.GetFileName(inPath), InStrRev(objFso.GetFileName(inPath),".") - 1) & "_SPACE_ADDED.csv")
' Read the file
set objTextFile = objFso.OpenTextFile(inPath)
'Now Creating the file can overwrite exiting file
set aNewFile = objFso.CreateTextFile(outPath, True)
aNewFile.Close
'Open the file to appending data
set aNewFile = objFso.OpenTextFile(outPath, 8) '2=Open for writing 8 for appending
' Reading data and writing it to new file
Do while NOT objTextFile.AtEndOfStream
arrStr = split(objTextFile.ReadLine,",")
sLine = "" 'Clear previous data
For i=lbound(arrStr) to ubound(arrStr)
sLine = sLine + " " + arrStr(i) + ","
Next
'Writing data to new file
aNewFile.WriteLine left(sLine, len(sLine)-1) 'Get rid of that extra comma from the loop
Loop
'Closing new file
aNewFile.Close
Next ' This is for next file
set aNewFile=nothing
set objFso = nothing
set objArgs = nothing
最简单的解决方案 我今天才想出来的。
用Word打开 用连字符替换所有连字符 保存并关闭 在Excel中打开
一旦你完成编辑,你可以再次在Word中打开它,再次用连字符替换破折号。
而创建字符串要写入我的CSV文件在c#中,我必须这样格式化它:
"=\"" + myVariable + "\""
None of the solutions offered here is a good solution. It may work for individual cases, but only if you're in control of the final display. Take my example: my work produces list of products they sell to retail. This is in CSV format and contain part-codes, some of them start with zero's, set by manufacturers (not under our control). Take away the leading zeroes and you may actually match another product. Retail customers want the list in CSV format because of back-end processing programs, that are also out of our control and different per customer, so we cannot change the format of the CSV files. No prefixed'=', nor added tabs. The data in the raw CSV files is correct; it's when customers open those files in Excel the problems start. And many customers are not really computer savvy. They can just about open and save an email attachment. We are thinking of providing the data in two slightly different formats: one as Excel Friendly (using the options suggested above by adding a TAB, the other one as the 'master'. But this may be wishful thinking as some customers will not understand why we need to do this. Meanwhile we continue to keep explaining why they sometimes see 'wrong' data in their spreadsheets. Until Microsoft makes a proper change I see no proper resolution to this, as long as one has no control over how end-users use the files.
