void ClearContents(
CellRange range
)
Sub ClearContents(
range As CellRange
)
| Name | Type | Description |
|---|---|---|
| range | CellRange |
A CellRange object specifying the cell range to clear.
|
The ClearContents method removes cell data (value and formula) only. Cell formatting and comments remain unchanged. Another way to do this is to assign the CellRange.Value property to null or to CellValue.Empty.
To separately remove cell formatting, hyperlinks, comments or clear a cell range completely, call the Worksheet.ClearFormats, Worksheet.ClearHyperlinks, Worksheet.ClearComments or Worksheet.Clear method, respectively. To delete entire cells from the worksheet, use the Worksheet.DeleteCells method (see the How to: Delete a Cell or Range of Cells example).
To clear cells, you can also use the range’s Clear* extension methods, defined by the RangeExtensions class (RangeExtensions.Clear, RangeExtensions.ClearContents, RangeExtensions.ClearFormats, RangeExtensions.ClearHyperlinks and RangeExtensions.ClearComments). These extension methods are accessible as methods of the CellRange object and called by using the instance method syntax.
This example demonstrates how to clear worksheet cells.

Clear Cell Formatting
Clear Cell Hyperlinks
Clear Cell Comments
// Remove all cell information (content, formatting, hyperlinks and comments).
worksheet.Clear(worksheet["C2:D2"]);
// Remove cell content.
worksheet.ClearContents(worksheet["C3"]);
worksheet["D3"].Value = null;
// Remove cell formatting.
worksheet.ClearFormats(worksheet["C4"]);
worksheet["D4"].Style = workbook.Styles.DefaultStyle;
// Remove hyperlinks from cells.
worksheet.ClearHyperlinks(worksheet["C5"]);
Hyperlink hyperlinkD5 = worksheet.Hyperlinks.GetHyperlinks(worksheet["D5"])[0];
worksheet.Hyperlinks.Remove(hyperlinkD5);
// Remove comments from cells.
worksheet.ClearComments(worksheet["C6"]);
' Remove all cell information (content, formatting, hyperlinks and comments).
worksheet.Clear(worksheet("C2:D2"))
' Remove cell content.
worksheet.ClearContents(worksheet("C3"))
worksheet("D3").Value = Nothing
' Remove cell formatting.
worksheet.ClearFormats(worksheet("C4"))
worksheet("D4").Style = workbook.Styles.DefaultStyle
' Remove hyperlinks from cells.
worksheet.ClearHyperlinks(worksheet("C5"))
Dim hyperlinkD5 As Hyperlink = worksheet.Hyperlinks.GetHyperlinks(worksheet("D5"))(0)
worksheet.Hyperlinks.Remove(hyperlinkD5)
' Remove comments from cells.
worksheet.ClearComments(worksheet("C6"))
