Clear a Single Cell Example

To clear the content of a selected cell, you can use the ClearContents method.

:path=/static-assets/excel/content-code-examples/how-to/clear-cells-clear-single-cell.cs
using IronXL;

// This line of code loads an existing Excel workbook named "sample.xlsx"
// into a WorkBook object, allowing you to manipulate the workbook's contents.
WorkBook workBook = WorkBook.Load("sample.xlsx");

// This line retrieves a worksheet named "Data" from the WorkBook object.
// It creates a WorkSheet object representing the "Data" worksheet 
// for subsequent operations.
WorkSheet workSheet = workBook.GetWorkSheet("Data");

// Clears the content of cell A1 in the "Data" worksheet.
// This method ensures that the specific cell is emptied of any existing data or formula.
workSheet["A1"].ClearContents();

// Saves the modified workbook to a new file named "clearSingleCell.xlsx".
// This stores the changes made to the workbook, such as the cleared cell, to a new file.
workBook.SaveAs("clearSingleCell.xlsx");
Imports IronXL

' This line of code loads an existing Excel workbook named "sample.xlsx"
' into a WorkBook object, allowing you to manipulate the workbook's contents.
Private workBook As WorkBook = WorkBook.Load("sample.xlsx")

' This line retrieves a worksheet named "Data" from the WorkBook object.
' It creates a WorkSheet object representing the "Data" worksheet 
' for subsequent operations.
Private workSheet As WorkSheet = workBook.GetWorkSheet("Data")

' Clears the content of cell A1 in the "Data" worksheet.
' This method ensures that the specific cell is emptied of any existing data or formula.
workSheet("A1").ClearContents()

' Saves the modified workbook to a new file named "clearSingleCell.xlsx".
' This stores the changes made to the workbook, such as the cleared cell, to a new file.
workBook.SaveAs("clearSingleCell.xlsx")

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;

// Load the workbook from the specified Excel file
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Get the worksheet named "Data" from the workbook
WorkSheet workSheet = workBook.GetWorkSheet("Data");

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

// Clear the contents of the entire column (B)
workSheet.GetColumn("B").ClearContents();

// Clear the contents of the entire row (4)
// Note: Row indices are zero-based, so 3 corresponds to the 4th row
workSheet.GetRow(3).ClearContents();

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

// Save the modified workbook to a new Excel file
workBook.SaveAs("clearCellRange.xlsx");
Imports IronXL

' Load the workbook from the specified Excel file
Private workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Get the worksheet named "Data" from the workbook
Private workSheet As WorkSheet = workBook.GetWorkSheet("Data")

' Clear the contents of a single cell (A1)
workSheet("A1").ClearContents()

' Clear the contents of the entire column (B)
workSheet.GetColumn("B").ClearContents()

' Clear the contents of the entire row (4)
' Note: Row indices are zero-based, so 3 corresponds to the 4th row
workSheet.GetRow(3).ClearContents()

' Clear the contents of a two-dimensional range (D6:F9)
workSheet("D6:F9").ClearContents()

' Save the modified workbook to a new Excel file
workBook.SaveAs("clearCellRange.xlsx")

Clear Worksheet Collection Example

In addition to clearing individual cells, you can also delete all worksheets in a workbook with ease. To achieve this, simply use the Clear method on the worksheet collection. This method allows you to remove all worksheets in one go, providing a convenient way to reset the workbook to its initial state.

:path=/static-assets/excel/content-code-examples/how-to/clear-cells-clear.cs
using IronXL;

// This code demonstrates how to load an Excel workbook, clear all worksheets within it, and save the modified workbook.

// Load the workbook from a specified Excel file
WorkBook workBook = WorkBook.Load("sample.xlsx");

// Clear all worksheets from the workbook
// This removes all sheets within the workbook, leaving it empty.
workBook.WorkSheets.Clear();

// Save the modified (cleared) workbook to a new file
workBook.SaveAs("useClear.xlsx");
Imports IronXL

' This code demonstrates how to load an Excel workbook, clear all worksheets within it, and save the modified workbook.

' Load the workbook from a specified Excel file
Private workBook As WorkBook = WorkBook.Load("sample.xlsx")

' Clear all worksheets from the workbook
' This removes all sheets within the workbook, leaving it empty.
workBook.WorkSheets.Clear()

' Save the modified (cleared) workbook to a new file
workBook.SaveAs("useClear.xlsx")
