(EXCEL 2016及以后版本，实际上我没有尝试过旧版本)

打开新空白页 转到“数据”标签 点击“来自文本/CSV”，选择CSV文件 检查预览您的数据是否正确。 在сase中，当某些列被转换为日期时，单击“编辑”，然后通过单击列头部的日历选择类型文本 点击“关闭并加载”

(假设Excel 2003…)

当使用文本到列向导时，在步骤3中，您可以为每个列指定数据类型。单击预览中的列，将行为不端的列从“常规”更改为“文本”。

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""" "

警告:Excel '07(至少)有一个(另一个)错误:如果字段的内容中有逗号，它不会正确解析="field, contents"，而是将逗号后的所有内容放入下面的字段中，而不管引号是什么。

我发现唯一有效的解决方法是当字段内容包含逗号时消除=。

这可能意味着有些字段不可能在Excel中完全“正确”地表示，但到目前为止，我相信没有人会感到太惊讶。

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.

另一种方法:

将要更改的列的格式转换为“Text”。选择要保留的所有单元格，复制。在不取消这些列的情况下，单击“编辑>粘贴特殊> As值”

保存为CSV。请注意，这必须是您对文件所做的最后一件事，因为当您重新打开它时，它将自己格式化为日期，因为单元格格式不能保存在CSV文件中。
