The ExcelService provides a means for applications to create and read Microsoft Excel documents. Since Microsoft Excel is so widely used, Excel documents can be a convenient way to exchange data between trading units or partners. An application may also use the service for extracting subsets of data from a corporate database for further analysis or presentation in an Excel workbook.
Due to the dependence on Apache POI, the ExcelService requires JDK 1.5 over higher.
When adding images to a sheet, only PNG and JPEG formats are supported.
The ExcelService is not dependent on other services.
The ExcelService supersedes the ExcelReadService due its superior capabilities, including supporting .xlsx format Excel files
