这个问题仍然存在于Mac Office 2011和Office 2013，我无法阻止它发生。这似乎是很基本的事情。

在我的例子中，我有诸如“1 - 2”和“7 - 12”的值，在CSV中正确地用倒逗号括起来，这将自动转换为excel中的日期，如果您尝试随后将其转换为纯文本，您将得到日期的数字表示形式，如43768。此外，它将条形码和EAN编号中的大数字重新格式化为123E+数字，再次无法转换回来。

我发现谷歌驱动器的谷歌表不能将数字转换为日期。条形码中每3个字符有一个逗号，但这些很容易被删除。它处理csv非常好，特别是在处理MAC / Windows csv时。

说不定还能救人。

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

SELECT CONCAT('\'',NOW(),'\''), firstname, lastname 
FROM your_table
INTO OUTFILE 'export.csv' 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '\"' 
LINES TERMINATED BY '\n'

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。

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.

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)。
