我有CSV文件，还有一个名为'Involved ST'的字段 该字段可以包含以下值：
之前：
Involved ST
V5 3rd
V4 3rd
V6 3rd
G140 2nd
G141 2nd
A2
A3
后：
Involved ST
3rd
3rd
3rd
2nd
2nd
1st
1st
现在我必须在 - ＆gt;中替换包含3rd的每个值（如'V5 3rd'）第三
包含2nd->的值第二
否则替换为1st。
哪种工具可以做到这一点？谢谢!!

如果在Excel中打开CSV，则可以使用如下公式：
=IF(A2<>"", CHOOSE(IFERROR(MATCH(RIGHT(A2,3),{"3rd","2nd"},0),3),"3rd","2nd","1st"),"")
或
=IF(A2<>"", IF(ISERROR(MATCH(RIGHT(A2,3),{"3rd","2nd"},0)),"1st",RIGHT(A2,3)), "")
（假设您的值从A2开始）
