如何在Word文档中为数字添加千位分隔符？

Author: Sun Last Modified: 2025-07-31

在Word文档中为数字添加千位分隔符可以显著提高可读性，尤其是在处理大数字时。虽然Microsoft Word没有直接提供添加千位分隔符的功能，但可以通过使用VBA（Visual Basic for Applications）或像Kutools for Word这样的便捷工具来高效实现这一目标。

在本教程中，我们将指导您如何使用VBA和Kutools for Word为Word文档中的数字添加千位分隔符。

使用VBA添加千位分隔符

将千位分隔符插入到大数字中可能会很繁琐，特别是当您需要重复操作时。通过使用VBA代码，您可以自动化此过程，只需选择一个数字并按下F5键即可立即添加分隔符。

选择要格式化为带千位分隔符的数字，然后按Alt + F11打开Microsoft Visual Basic for Applications窗口。
