Microsoft Excel is one of the most popular spreadsheet formats. An Excel sheet can be used as a datasource for creating data services in WSO2 Enterprise Integrator (WSO2 EI).

About the sample

The Products.xls file, stored in the <EI_HOME>/samples/data-services/resources/ folder, is used as the datasource to demonstrate this sample data service. This datasource contains details of the products manufactured in an automobile company. Products refer to cars/motorocyles. The data table has the following columns: "ID", "Name", "Classification" and "Price" (same as in the CSV Sample)This sample data service contains two operations:

  • getProducts: Lists all the products that are manufactured by the company. Each record in the result will contain "ID" and "Name" fields.
  • getProductClassifications: Lists all the products along with the classifications. The result is presented with two records: "Name" and "classification".

See Data integration for a definition of data services and operations.
