The IronXL library allows you to remove all empty rows and columns on the range borders in C# code without using Office Interop. This feature facilitates efficient data processing and manipulation without the overhead associated with the Office suite.

Quickstart: Trim Borders of a Cell Range with IronXL

Here’s a super-simple example showing how to trim all empty rows and columns around a selected column using IronXL in C#. Just one API call does the job—no complex setup required.

Minimal Workflow (5 steps)

  1. Download the C# library to trim cell ranges
  2. Open an existing or create a new Excel spreadsheet
  3. Select a range, row, or column to be trimmed
  4. Use the Trim method on the selected range, row, or column
  5. Check the returned Range of the trim method


Trim Cell Range Example

Select the desired Range of cells and apply the Trim method on it. This method trims leading and trailing empty cells from the selected range.

提示The Trim method does not remove empty cells located in the middle of rows and columns within the range. To address this, you can apply sorting to push those empty cells to either the top or bottom of the range.

using IronXL;

WorkBook workBook = WorkBook.Create(ExcelFileFormat.XLSX);
WorkSheet workSheet = workBook.DefaultWorkSheet;

workSheet["A2"].Value = "A2";
workSheet["A3"].Value = "A3";

workSheet["B1"].Value = "B1";
workSheet["B2"].Value = "B2";
workSheet["B3"].Value = "B3";
workSheet["B4"].Value = "B4";

// Retrieve column
RangeColumn column = workSheet.GetColumn(0);

// Apply trimming
Range trimmedColumn = workSheet.GetColumn(0).Trim();
Imports IronXL

Private workBook As WorkBook = WorkBook.Create(ExcelFileFormat.XLSX)
Private workSheet As WorkSheet = workBook.DefaultWorkSheet

Private workSheet("A2").Value = "A2"
Private workSheet("A3").Value = "A3"

Private workSheet("B1").Value = "B1"
Private workSheet("B2").Value = "B2"
Private workSheet("B3").Value = "B3"
