Compare by unique key

[houdelou]

Hi,

Is there a way to compare a CSV file by using a unique key column ?

For example

File 1
1,cat
2,dog

File 2
1,cat
3,dog

Is there a way Winmerge could say : "Record with id 2 is missing from file 2 and record with id 3 is missing in file 1" ?

Thanks

Unfortunately, WinMerge doesn't have such a feature.

Ok, thanks. Maybe it is not the purpose of the tool but I had to ask because I need such a tool. Thanks for the quick reply.
