I have to write data from “excel A” to “excel B”. The solution I tried is Read the range, then write to data table… 20.000 data and it took 1 minute to write it. Any solution to make it more faster? The number of column written from excel A to excel B is only 1 (Column A)… If I add Column B it will took 2 minute.
Also tried to loop for each and assign to data row and it still took 1 minute. Any solution to make it more faster?
The current data is Excel A where Customer Name is on Column A, and Customer ID is on column M (Assumption column B until column L has data inside it)
The expected output is customer name on column A and customer ID is on column B in a new excel file (write data table to new excel file). How to execute this?
