用Excel查找单元格中的某些字符

我有一个链接可以粘贴的单元格。 例如： https : //stackoverflow.com/questions/ask

如果文本中包含“ / ”或“ ： ”或“ = ”，我希望旁边的单元格显示“错误”。 应该说“正确”是这三个字符都没有在文本中find。

For example: test/ Would give "Wrong" because it contains at least 1 "/" /test: Would give "Wrong" because it contains at least 1 ":" and at least 1 "/" test/////// Would give "Wrong" because it contains at least 1 "/" test/:= Would give "Wrong" because it contains at least 1 "/", at least 1 ":" and at least 1 "/" test123{}+_) Would give "Correct" because it does not contain any "/", ":" or "=" 

我试图与嵌套的IF工作，但我不能得到它的工作。 在公式中添加第三个字符时，我不断收到错误。

Answer 1

尝试这个

 =IF(OR(ISNUMBER(SEARCH("/",A1)),ISNUMBER(SEARCH(":",A1)),ISNUMBER(SEARCH("=",A1))),"Wrong","Correct") 

或者优先考虑这一个

 =IF(OR(ISNUMBER(SEARCH({"/",":","="},A1))),"Wrong","Correct") 

看图像以供参考。
