如何从Google文档或Excel中的date时间string中删除序号？

我有一个date时间的列表，碰巧有他们的序数（第一，第二，第三）。 这会导致使用date和转换为unix时间的问题。

如何从date中删除“rd”或“th”后缀？

示例date：

April 23rd Apr 24th Apr 30th May 1st May 7th May 8th May 15th May 21st May 22nd May 28th Jun 18th Jun 19th Jun 26th 

Answer 1

尝试这个：

 =SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,"st",""),"nd",""),"rd",""),"th","") 

并将其转换为今年的“实际”date：

 =--SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,"st",""),"nd",""),"rd",""),"th","") 

或者更短（在Excel中工作，不确定Google）：

 =LOOKUP(1E+307,--SUBSTITUTE(A1,{"st","nd","rd","th"},"")) 

请务必将其格式化为date

Answer 2

如果date只是文本，并且总是有最后两个字母，那么它就是

 =LEFT(A1,LEN(A1)-2) 

如果你想检查那些信是在那里，你可以使用类似的东西

 =IF(OR(RIGHT(A1,2)={"st","nd","rd","th"}),LEFT(A1,LEN(A1)-2),A1) 

必须在Google表格中input为数组公式

 =ArrayFormula(=IF(OR(RIGHT(A1,2)={"st","nd","rd","th"}),LEFT(A1,LEN(A1)-2),A1))
