I would like to ask ,if I have four excel file
I want at first to compare between two attributes ,Id attribute ,both of them should have the same attribute but some times one excel file has more than another.
So ,I would like to check which has more and
If first excel file has more than the second excel file so I want to know the new id and extract for each new Id from the third file the data in this row belongs to this id.
And at the same time If the second file has more id than first time ,so I would like to extract know which Id is more in second file and add them to first file and extract the data from the fourth excel file .
So I want both of excel file ,first and second should be matched in Id and each one extract the missing data from separated file .
Because only common between first and second is Id and the rest of data from another two files
