I suggest you can use string "Null" instead of "NULL" using Derived
Column Transformation, and then load the data to Excel Destination.
Please refer to the steps about configuring the Derived Column
Transformation as below:
1. Open the Derived Column Transformation Editor, Select "Replace ColumnName" in the "Derived Column".
2. Write expression "ISNULL(ColumnName) ? "Null" : ColumnName" in the "Expression".
1. Open the Derived Column Transformation Editor, Select "Replace ColumnName" in the "Derived Column".
2. Write expression "ISNULL(ColumnName) ? "Null" : ColumnName" in the "Expression".
