Updating Row in excel

[opteamix_bot (Pankaj)]

Hi, I am working on reading my mail box and updating L in excel sheet dynamically the date employee applies for leave . If the employee Cancels leave , I just want to remove the L from the date dynamically but in my case it is creating a new row rather than updating on the existing row.

I am using ‘Add data row’. Is there any Activity to update it.
