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.

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

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

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。
