Set Excel Margins

In this tutorial, we will walk you through step by step how to set margins in Excel using Aspose.Cells for .NET. We will use C# source code to illustrate the process.

Step 1: Setting up the environment

Make sure you have Aspose.Cells for .NET installed on your machine. Also create a new project in your preferred development environment.

Step 2: Import necessary libraries

In your code file, import the libraries needed to work with Aspose.Cells. Here is the corresponding code:

using Aspose.Cells;

Step 3: Set Data Directory

Set the data directory where you want to save the modified Excel file. Use the following code:

string dataDir = "YOUR DATA DIRECTORY";

Be sure to specify the full directory path.

Step 4: Creating the workbook and worksheet

Create a new Workbook object and navigate to the first worksheet in the workbook using the following code:

Workbook workbook = new Workbook();
WorksheetCollection worksheets = workbook. Worksheets;
Worksheet worksheet = worksheets[0];

This will create an empty workbook with a worksheet and provide access to that worksheet.

Step 5: Setting Margins

Access the worksheet’s PageSetup object and set the margins using the BottomMargin, LeftMargin, RightMargin, and TopMargin properties. Here is a sample code:

PageSetup pageSetup = worksheet.PageSetup;
pageSetup.BottomMargin = 2;
pageSetup.LeftMargin = 1;
pageSetup.RightMargin = 1;
pageSetup.TopMargin = 3;

This will set the bottom, left, right, and top margins of the worksheet respectively.

Step 6: Saving the Modified Workbook

Save the modified workbook using the following code:

workbook.Save(dataDir + "OutputFileName.xls");

This will save the modified workbook to the specified data directory.

Sample source code for Set Excel Margins using Aspose.Cells for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
// Create a workbook object
Workbook workbook = new Workbook();
// Get the worksheets in the workbook
WorksheetCollection worksheets = workbook.Worksheets;
// Get the first (default) worksheet
Worksheet worksheet = worksheets[0];
// Get the pagesetup object
PageSetup pageSetup = worksheet.PageSetup;
// Set bottom,left,right and top page margins
pageSetup.BottomMargin = 2;
pageSetup.LeftMargin = 1;
pageSetup.RightMargin = 1;
pageSetup.TopMargin = 3;
// Save the Workbook.
workbook.Save(dataDir + "SetMargins_out.xls");
