如何在Word文檔中為數字添加千位分隔符？

Author Sun Last modified 2025-08-23

在Word文檔中為數字添加千位分隔符可以大大提升可讀性，特別是在處理大數字時。雖然Microsoft Word沒有直接提供添加千位分隔符的功能，但可以通過使用VBA（Visual Basic for Applications）或像Kutools for Word這樣的便捷工具來實現這一目的。

在本教程中，我們將引導您完成使用VBA和Kutools for Word為Word文檔中的數字添加千位分隔符的步驟。

將千位分隔符插入到大數字中可能會很繁瑣，特別是當你需要重複操作時。通過使用VBA代碼，你可以自動化這個過程，只需選擇一個數字並按下F5鍵即可立即添加分隔符。

選擇你想要格式化為帶有千位分隔符的數字，然後按Alt + F11打開Microsoft Visual Basic for Applications窗口。

        End If
    Else
        MsgBox "Please select a number first."
    End If
