In that case you use join datatable activity in UiPath, where you can pass the first datatble and second datatable and make join with names as inner join and get the final output datatable separately.
hu
this can give you a fine idea about using join table
Else if you want to use vlookup, we have an option called lookup datatable activity where you can pass the column Name as lookup column in the property and check with first excel datatable, but my kind suggestion is to take the first option, that would work
Hope this would help you
Cheers
