Facing issue while inserting data on excel

I have excel file which contain two sheet name one is i/p sheet and another is o/p sheet name.Now i/p sheet almost 5 k records.I am executing each records using for each loop.let suppose ten records executed I am inserting data of those ten records with some values in o/p sheet using add row then write range and also In input sheet name I created one column with the name of flag those records is executed so second run that record not execute.
Problem occur when I try to run second time o/p sheet records replace older records with new records.
I want when second run I am executing it insert data from 11 records in output sheet not from first.

Hy @aadi.kaistha,

You can use the ‘append range’ activity to insert records below the existing ones in the excel sheet.
Is this what you want?!
