Insert or Delete Rows in an Excel Worksheet

When creating a new worksheet, or working with an existing worksheet, you might need to add extra rows or columns to accommodate data. At other times, you might need to delete rows or columns from specified positions in the worksheet.

Aspose.Cells offers two methods for inserting and deleting rows: Cells.InsertRows and Cells.DeleteRows. These methods are optimized for performance and do the job very quickly.

To insert or remove a number of rows, we recommend that you always use the Cells.InsertRows and Cells.DeleteRows methods instead of using the Cells.InsertRow or DeleteRow methods in a loop.

Aspose.Cells works in the same way as Microsoft Excel does. When rows or columns are added, the worksheet content is shifted down and to the right. When rows or columns are removed, the worksheet content is shifted up or to the left. Any references in other worksheets and cells are updated when rows are added or removed.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a Workbook object.
// Load a template file.
Workbook workbook = new Workbook(dataDir+ "book1.xlsx");

// Get the first worksheet in the book.
Worksheet sheet = workbook.Worksheets[0];

// Insert 10 rows at row index 2 (insertion starts at 3rd row)
sheet.Cells.InsertRows(2, 10);

// Delete 5 rows now. (8th row - 12th row)
sheet.Cells.DeleteRows(7, 5);

// Save the excel file.
workbook.Save(dataDir+ "out_book1.out.xlsx");
