Append Row Number in DataTable Activities

Hi everyone, i’d like to share my new custom activity. Feel free to use it and ask any questions

This activity is useful for scenarios where you need to know the corresponding Excel row number of each row in a DataTable.


  1. Starting row number (Integer) - e.g. if the table in Excel starts at row 3, then the starting row number is equal to 3, the second item will = 4 and so on.

  2. Name of the column (String) - This is how you will refer to the column e.g. if name = “Row Number” , then you refer by row (“Row Number”).
