i had some research to SUM datatable from certain column in excell, i found that activity DataTable Manipulation can cover it.
Already tried it but had some error :
Math Operations: Cannot cast DBNull.Value to type ‘System.Double’. Please use a nullable type.
here the Screenshoot :
Output Value (dt_test) using Variable type Double.
anyone please help me recommend solution to SUM value from certain column in datatable excel?
