Step 2: Select the framework version.

Step 3: Name the application.

Step 4: Install the Syncfusion.XlsIO.Net.Core NuGet package as reference to your application from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your applications to use our components.

Step 5: Include the following Namespaces in the Program.cs file.

C#

using Syncfusion.XlsIO;
using System.Drawing;
using System.Reflection;

Step 6: Add the following code snippet in Program.cs file.

C#

  FileStream outputStream = new FileStream("Output.xlsx", FileMode.Create);
  workbook.SaveAs(outputStream);
  outputStream.Dispose();
  imageStream.Dispose();
}

By executing the program, you will get the Excel file as below.

Read and Edit Excel file

The below code snippet illustrates how to read and edit an Excel file on Mac OS.

C#

//New instance of ExcelEngine is created 
//Equivalent to launching Microsoft Excel with no workbooks open
//Instantiate the spreadsheet creation engine
ExcelEngine excelEngine = new ExcelEngine();

//Instantiate the Excel application object
IApplication application = excelEngine.Excel;

//Assigns default application version
application.DefaultVersion = ExcelVersion.Xlsx;

//A existing workbook is opened.             
Assembly executingAssembly = typeof(Program).GetTypeInfo().Assembly;
Stream inputStream = executingAssembly.GetManifestResourceStream("XlsIOSample.Sample.xlsx");
IWorkbook workbook = application.Workbooks.Open(inputStream);

//Access first worksheet from the workbook.
IWorksheet worksheet = workbook.Worksheets[0];

//Set Text in cell A3.
worksheet.Range["A3"].Text ="Hello World";

//Access a cell value from Excel
var value = worksheet.Range["A1"].Value;

//Initialize stream
FileStream outputStream = new FileStream("Output.xlsx", FileMode.Create);

//Save the workbook as stream
workbook.SaveAs(outputStream);

//Dispose the streams
outputStream.Dispose();
inputStream.Dispose();

workbook.Close();
excelEngine.Dispose();
