We have already demonstrated how to add page breaks in Excel worksheet in C# with the help of Spire.XLS. Spire.XLS supports to remove all the horizontal and vertical page breaks and it also supports to remove the special page breaks. Here comes to the steps of how to remove the page breaks from an Excel worksheet.

Firstly, view the same Excel document with horizontal page breaks and vertical page breaks:

Step 1: Initialize an instance of Workbook and load the document from file.

Workbook workbook = new Workbook();
workbook.LoadFromFile("Sample.xlsx");

Step 2: Get the first worksheet from the workbook.

Worksheet sheet = workbook.Worksheets[0];

Step 3: Clear all the vertical page breaks by call the VPageBreaks.Clear() method.

sheet.VPageBreaks.Clear();

Step 4: Remove the specified horizontal Page Break by call the HPageBreaks.RemoveAt() method.

sheet.HPageBreaks.RemoveAt(0);

Step 5: Set the ViewMode as Preview to see how the page breaks work.

sheet.ViewMode = ViewMode.Preview;

Step 6: Save the document to file.

workbook.SaveToFile("RemovePageBreak.xlsx", FileFormat.Version2010);
