Aspose.Cells - Export Data from Worksheets
Aspose.Cells not only lets its users import data to worksheets from external data sources but also allow them to export worksheet data to an array.
Java
//Creating a file stream containing the Excel file to be opened
FileInputStream fstream = new FileInputStream(dataDir + "workbook.xls");
//Instantiating a Workbook object
Workbook workbook = new Workbook(fstream);
//Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
//Exporting the contents of 7 rows and 2 columns starting from 1st cell to Array.
Object dataTable [][] = worksheet.getCells().exportArray(4,0,7,8);
for (int i = 0 ; i < dataTable.length ; i++)
{
System.out.println("["+ i +"]: "+ Arrays.toString(dataTable[i]));
}
