4. You can directly specify the details of the spreadsheet as shown below.
   
5. Define Output Mapping: Now, let's specify how the data fetched from the datasource should be displayed in the output. The sample Excel datasource we are using contains three columns: ID, Model and Classification. We will create an output mapping for each of these columns.  
   1. In the  Output type  field, specify the format in which the query results should be presented. You can select XML, JSON or RDF. We will use  XML  for this tutorial.
   2. In the Grouped by element  field, specify a grouping for all the output mappings. This will be the XML element that will group the query result. Enter Products in this field. 
   3. In the Row Name field, specify the XML element that should group each individual result. Enter Product in this field.
   4. Click  Add New Output Mapping  to start creating the output mapping for the  ID  column. Enter values as shown below:
      
   5. Click Add to save the output mapping.

   6. Create output mappings for the remaining columns given below.

      Mapping Type	Element Name	Datasource Type	Datasource Column Name	Parameter Type	Schema Type
      Element	Model	Column	Model	SCALAR	string
      Element	Classification	Column	Classification	SCALAR	string
