是否有任何数据验证可强制用户仅允许不区分大小写的字母？

Question

我希望单元格抛出错误“ Only enter alphabets. Not allow special characters and Numbers"。即使我输入DOT .，它也应该抛出停止错误消息。

可以进行数据验证吗？

示例：

ANIL KUMAR .P is ERROR
and ANIL KUMAR P is RIGHT

不允许：

特殊字符：

"!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~"

数字：0123456789

您可以使用自定义DV公式，例如：

=AND(MIN(CODE(MID(UPPER(SUBSTITUTE(A1," ","")),ROW(INDIRECT("1:"&LEN(SUBSTITUTE(A1," ","")))),1)))>64,MAX(CODE(MID(UPPER(SUBSTITUTE(A1," ","")),ROW(INDIRECT("1:"&LEN(SUBSTITUTE(A1," ","")))),1)))<91)

确保取消选中“忽略空白”选项。
