This technical tip show how developers can Copy Range Data with Style in an Excel Workbook inside Java Applications. Copy Range Data Only explained how to copy the data from a range of cells to another range. Aspose.Cells can also copy a range complete with formatting. This article explains how to achieve this task. Aspose.Cells provides a range of classes and methods for working with ranges, for example createRange(), StyleFlag, applyStyle() etc. This example explains how to:

• Creates a workbook.
• Fills a number of cells in the first worksheet with data.
• Creates a range.
• Creates a style object with specified formatting attributes.
• Applies the style to the data range.
• Creates a second range of cells.
• Copies data with the formatting from the first range to the second range.

Copy a Range of Data with Style  in a Workbook

[Java]

String filePath = "F:/Downloads/source.xlsx";

//Load your source workbook
Workbook workbook = new Workbook(filePath);

//0-byte array
byte[] workbookData = new byte[0];

//Text save options. You can use any type of separator
TxtSaveOptions opts = new TxtSaveOptions();
opts.setSeparator('\t');

//Copy each worksheet data in text format inside workbook data array
for (int idx = 0; idx < workbook.getWorksheets().getCount(); idx++)
{
    //Save the active worksheet into text format
    ByteArrayOutputStream bout = new ByteArrayOutputStream();
    workbook.getWorksheets().setActiveSheetIndex(idx);
    workbook.save(bout, opts);

    //Save the worksheet data into sheet data array
    byte[] sheetData = bout.toByteArray();

    //Combine this worksheet data into workbook data array
    byte[] combinedArray = new byte[workbookData.length + sheetData.length];
    System.arraycopy(workbookData, 0, combinedArray, 0, workbookData.length);
    System.arraycopy(sheetData, 0, combinedArray, workbookData.length, sheetData.length);

    workbookData = combinedArray;
}

//Save entire workbook data into file
FileOutputStream fout = new FileOutputStream(filePath + ".out.txt");
fout.write(workbookData);
fout.close();
