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!

在我的案例中，使用R生成的csv文件中的“Sept8”被Excel 2013转换为“8-Sept”。该问题通过使用xlsx包中的write.xlsx2()函数生成xlsx格式的输出文件来解决，该输出文件可以由Excel加载，而无需进行不必要的转换。因此，如果给你一个csv文件，你可以尝试将它加载到R中，并使用write.xlsx2()函数将其转换为xlsx。

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'

如果有人还在寻找答案，下面这句话对我来说非常合适

我输入=("my_value")。 即=("04SEP2009")显示为04SEP2009，而不是09/04/2009

这同样适用于大于15位的整数。他们不再修剪了。

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""" "
