I am using modernview I am using excel read stream to use data table in for each loop. I am fetching order id from excel and searching in order application search box. If found it iterate the loop. Excel contains 3 column order, id, can number. No header stored. Now I have to add 4th column to update whether it is found or not. I tried write cell and write stream not working. Seeking your expertise please how to sort this scenario out.
