excel - 修剪 Excel 单元格中的前导空格

Question

如何去掉 excel 中的前导空格?

我有很多行有这个问题。

Answer 1

在您的空格删除请求中，请注意:

TRIM仅删除字符 32，即标准空格。

CLEAN将删除非打印空格，例如回车符(字符 13)和换行符(字符 10)

CLEAN不处理不间断空格(字符 160)，这是处理来自网络的数据的常见问题，为此您需要 SUBSTITUTE功能

您可以使用整个单元格上的公式来执行此操作，或者使用 vba 更轻松地(并针对前导空格)执行此操作。

使用公式，您可以结合使用这三个公式来清理整个单元格，就像这样=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," "))) .请参阅 Ron de Bruins 的文章 here

下面的 VBA 将使用数组和正则表达式有效地就地替换您的数据，而无需任何工作列以及复制和粘贴。使用说明包含在下面的代码中。此代码仅适用于字符串的前导部分，与公式选项不同
