How to extract specific data from excel column and write the extracted data into another column of same excel file

@Rahul Thanks a lot it’s working fine for me.
To write the value of extracted data in same xsl file of “summary” column i am using write cell activity inside the Excel application scope.In the properties of write cell activity,in range field i am giving “B3”,in sheetname field i am giving “Sheet1” and in value field i am passing the “output” variable(which store extracted data) working fine.is it standard method to complete this work?

when more input data then have i write multiple write cell for each input data.Is it right method?
