@priya_joshi_thaneti Just think final excel has 2 columns(Name and age) and input excel has columns( Name, Place, Age).
read both final and input excel sheets and output will be dt and dt1 datatable variables respectively.
Use for each datarow with input datatable variable which is output of final excel(ie, dt)
3) inside for each datarow loop use assign activity
row(1) = dt1.Select(“[Name]='”+row(0).ToString+“'”).(0)(2).ToString
In this statement (0)(2) means zeroth row and 2nd column and Name is the column
name and row(0) represents first column, each time loop runs row(0) gets new value
from next row.
Finally write the dt datatable to final excel again.
change the things according to your requirement, if you any doubt let me know.
