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.

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。

这是我知道如何在不搞乱文件本身的情况下完成这一点的唯一方法。就像使用Excel一样，我用头在桌子上敲了几个小时才学会这一点。

Change the .csv file extension to .txt; this will stop Excel from auto-converting the file when it's opened. Here's how I do it: open Excel to a blank worksheet, close the blank sheet, then File => Open and choose your file with the .txt extension. This forces Excel to open the "Text Import Wizard" where it'll ask you questions about how you want it to interpret the file. First you choose your delimiter (comma, tab, etc...), then (here's the important part) you choose a set columns of columns and select the formatting. If you want exactly what's in the file then choose "Text" and Excel will display just what's between the delimiters.

这周我刚刚遇到了这个惯例，它似乎是一个很好的方法，但我在任何地方都找不到它。有人熟悉吗?你能举出出处吗?我没有找了几个小时，但我希望有人会认识到这种方法。

例1:=("012345678905")显示为012345678905

例2:=("1954-12-12")显示为1954-12-12，而不是12/12/1954。

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。

我在Excel 2003和2007中找到了一个简单的方法。打开一个空白的xls工作簿。然后进入数据菜单，导入外部数据。选择您的csv文件。通过向导，然后在“列数据格式”中选择任何需要强制“文本”的列。这将以文本格式导入整个列，防止Excel试图将任何特定的单元格作为日期处理。
