Hello everyone!!

From an Excel sheet ,how to keep only the group of columns which match with similar data from other Excel sheet:

For example,



The data in excel sheet 1 is

DAY HOUR MINUTE VARIABLE_1_VALUE
1 6 24 25
2 8 36 18
3 12 40 76

and so on.......

The data in excel sheet 2 is having much more details than compared to excel sheet 1 but for a different variable value having similar time stamp, say:

DAY HOUR MINUTE VARIABLE_2_VALUE
1 6 24 42
1 8 40 14
1 12 32 8
2 8 36 18
2 8 46 90
3 12 40 69
3 16 50 5

I want to select only those rows from excel sheet 2 which have common time stamp as that of excel sheet 1 which have on them .

Please help me out !!

Thanks in advance !!
