如何强制excel不“检测”日期格式而不编辑源文件

:

将文件重命名为.txt 如果你不能这样做，而不是直接在excel中打开CSV文件，创建一个新的工作簿，然后转到 数据>从文本中获取外部数据>并选择您的CSV。

无论哪种方式，你都会看到导入选项，只需选择每个包含日期的列，并告诉excel格式为“文本”而不是“一般”。

如果在字段的开头放置一个倒置逗号，它将被解释为文本。

例子: 25/12/2008变成了25/12/2008

您还可以在导入时选择字段类型。

我对不断转换为科学符号的信用卡号这样做:我最终将.csv导入到谷歌Sheets中。导入选项现在允许禁用数字值的自动格式化。我将任何敏感列设置为纯文本并下载为xlsx。

这是一个糟糕的工作流程，但至少我的价值观保持了原样。

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.

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 + "\""

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。
