Hi,
Initialize an int32 variable counter with value 1, then loop through your datatable and for each row, set the value with column name ‘#’ to the counter.
Increment the counter on each loop.

Finally write the datatable back to the Excel

Thanks, but I have a doubt… as a first step i have to count no of rows till subtotal row in excel, based on the no of row count i have to update the serial number. can i do that using the above method

Surely, you can add an “if” condition to check when your counter is equal to the row count, you can use a “break” activity to break out of the “For Each Row in DataTable” activity.

For Each r as Datarow in DT.Asenumerable
r(“S_No”)=DT.Rows.index(r)+1
Next r

For less code, you can use the currentRow index instead of the counter variable.
