我有一个excel表,看起来像这样:
Row Name
1 uniqueName001_vid1.mpg
2 uniqueName001.mpg
3 uniqueName002_vid1.mpg
4 uniqueName002_vid2.mpg
5 uniqueName002.mpg
我试图弄清楚如何在表格中识别和标记(给出一个唯一的ID)集合,其中包含相同的 uniqueName 。例如,Row的1和2将是一组,而Row的3,4和5将是另一组。
我理想的结果是:
Row Name UID
1 uniqueName001_vid1.mpg SET1
2 uniqueName001.mpg SET1
3 uniqueName002_vid1.mpg SET2
4 uniqueName002_vid2.mpg SET2
5 uniqueName002.mpg SET2
我可以在excel中运行SQL查询,如果这是比excel公式更好的选择。
非常感谢任何建议!

如果一切都以uniqueNameXXX开头而不是
Row Name UniqueName Unique# UID
1 uniqueName001_vid1.mpg =LEFT(F4;13) =IF(G3<>G4;H3+1;H3) ="UID"&H4
如果没有,则应该定义如何获取uniqueName

您可以使用VBA
执行该任务。
我为你做了一个小工具。照顾可编辑的部分 根据声明。
此工具会侦听数字 - 意思是,我希望您的模式始终与您在问题中所写的相同。
告诉我这是否有帮助:
