You need a license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use these examples in production code.

This article describes how to get started with the non-visual Spreadsheet component for .NET Framework and .NET Core.

Create a .NET Framework Application

1. Start Visual Studio and create a new Console Application (.NET Framework) project.

2. Install the DevExpress.Document.Processor NuGet package or add references to the following libraries (if you have the DevExpress Unified Component Installer installed on your machine):

   • DevExpress.Charts.v24.2.Core.dll
   • DevExpress.Data.v24.2.dll
   • DevExpress.DataAccess.v24.2.dll
   • DevExpress.DataVisualization.v24.2.Core.dll
   • DevExpress.Docs.v24.2.dll
   • DevExpress.Drawing.v24.2.dll
   • DevExpress.Office.v24.2.Core.dll
   • DevExpress.Pdf.v24.2.Core.dll
   • DevExpress.Printing.v24.2.Core.dll
   • DevExpress.Sparkline.v24.2.Core.dll
   • DevExpress.Spreadsheet.v24.2.Core.dll
   • DevExpress.TreeMap.v24.2.Core.dll
   • DevExpress.XtraCharts.v24.2.dll
   • DevExpress.XtraTreeMap.v24.2.dll

3. Open the Program.cs (Module1.vb) file. Paste the code below in the Main method of the Program class (Main procedure of the Module1 module in Visual Basic).

   C#

   using DevExpress.Spreadsheet;
   using System.Drawing;
   
   namespace SpreadsheetConsoleApp
   {
       class Program
       {
           static void Main(string[] args)
           {
               // Create a new workbook.
               using (Workbook workbook = new Workbook())
               {
                   // Access the first worksheet in the workbook.
                   Worksheet worksheet = workbook.Worksheets[0];
   
                   // Set the unit of measurement.
                   workbook.Unit = DevExpress.Office.DocumentUnit.Point;
   
                   workbook.BeginUpdate();
                   try

                           // Create the header row.
                           worksheet.Rows["1"][i].Value = i;
                       }
   
                       // Multiply values of header cells.
