Clear Cell Range Example

This method is available in the Range class, allowing you to execute it on any range, regardless of its size. Here are some examples:

Clear a single cell:
- workSheet ["A1"].ClearContents()
Clear a column:
- workSheet.GetColumn("B").ClearContents()
Clear a row:
- workSheet.GetRow(3).ClearContents()
Clear a two-dimensional range (multiple rows and columns):
- workSheet ["D6:F9"].ClearContents()

:path=/static-assets/excel/content-code-examples/how-to/clear-cells-clear-cell-range.cs

using IronXL;

WorkBook workBook = WorkBook.Load("sample.xlsx");
WorkSheet workSheet = workBook.GetWorkSheet("Data");

// Clear a single cell(A1)
workSheet["A1"].ClearContents();

// Clear a column(B)
workSheet.GetColumn("B").ClearContents();

// Clear a row(4)
workSheet.GetRow(3).ClearContents();

// Clear a two-dimensional range(D6:F9)
workSheet["D6:F9"].ClearContents();

workBook.SaveAs("clearCellRange.xlsx");

Imports IronXL

Private workBook As WorkBook = WorkBook.Load("sample.xlsx")
Private workSheet As WorkSheet = workBook.GetWorkSheet("Data")

' Clear a single cell(A1)
