How to copy a Excel column to a Java list

Question

I would like to extract the entire column from an excel worksheet to a Java array using the Aspose library. How do I do that? In many of the examples, I see how to copy a column/row from one worksheet to another only. Can Aspose extract data?

Answer 1

Yes, data can be easily exported to an Array using the exportArray method, see the sample code for your reference:

Example

// Instantiating a Workbook object
Workbook workbook = new Workbook("Book1.xlsx");

// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);

// Exporting the contents of 100 rows and 1 column starting from 1st cell (i.e., A1:A100)
// to Array. you may update the method parameters for your needs
Object dataTable[][] = worksheet.getCells().exportArray(0, 0, 100, 1);

// Printing number of rows after exporting worksheet data
System.out.println("No. Of Rows Imported: " + dataTable.length);
