I am trying to validate 2 excel sheets with 12,000 and above data, I have used a simple if condition workflow to compare the rows and if rows matched then write “YES” in a new column. The issue is, when I run the program it takes too much of time to get executed, I am not getting the output at all.
(eg: when I tried to validate sheets with “119222” data it is executed for about an hour but no output!)
Could you also confirm on whether a Run operation was performed or a Debug ?
If a Debug was performed, it would execute in a very slow manner.
Also, You would not need to use a For Each Row Loop for the inner Data Comparison. We would just need to check if the data is present in any of the rows in the dt_DB datatable, as the updation needs to be done only in the dt_Legacy datatable.
