Get the Counts of the data row and for(COUNT COLUMN) FULLY Filled by the value "0"

INPUT FILE

need a output like this

@krishnapriya_Anu

Please use write cell with cell as C2" and value as "0"

Then use auto fill range activity which will fill the data till end of data

Or else read the data into datatable using read range …then use assign with
dt.Columns("Count").Expression = "'0'"

Then use write range and write the data back to excel

Cheers
