Hi,

the source file you have attached cannot be read by UniversalDataReader since it does contain heterogeneous data (the rows does not have the same structure). Instead of UniversalDataReader you might use ComplexDataReader - for more information refer to our [documentation](http://doc.cloveretl.com/documentation/UserGuide/index.jsp?topic=/com.cloveretl.gui.docs/docs/complexdatareader.html).

Hope this helps.
