Delete Blank Rows and Columns in a Worksheet

It is possible to delete all blank rows and columns from a worksheet. This is useful for example when generating a PDF file from a Microsoft Excel file and you want to convert only rows and columns that contain data.

Use the following Aspose.Cells methods to delete empty rows and columns:

1. To delete blank rows, use the Cells.deleteBlankRows() method.
2. To delete blank columns, use the Cells.deleteBlankColumns() method.

// The path to the documents directory.
String dataDir = Utils.getDataDir(DeletingBlankRows.class);
// Create a new Workbook. Open an existing excel file.
Workbook wb = new Workbook(dataDir + "Book1.xlsx");

// Create a Worksheets object with reference to the sheets of the Workbook.
WorksheetCollection sheets = wb.getWorksheets();

// Get first Worksheet from WorksheetCollection
Worksheet sheet = sheets.get(0);

// Delete the Blank Rows from the worksheet
sheet.getCells().deleteBlankRows();

// Save the excel file.
wb.save(dataDir + "Output.xlsx");
