+# How to compute the size of the Excel file?
+
+Step 1: Create a New C# Console Application Project.
+
+Step 2: Name the Project.
+
+Step 3: Install the [Syncfusion.XlsIO.Net.Core](https://www.nuget.org/packages/Syncfusion.XlsIO.Net.Core) NuGet package as reference to your .NET Standard applications from [NuGet.org](https://www.nuget.org).
+
+Step 4: Include the following namespaces in the **Program.cs** file.
+
+```csharp
+using System;
+using System.IO;
+using Syncfusion.XlsIO;
+```
+
+Step 5: Include the below code snippet in **Program.cs** to compute the size of the Excel file.
+
+```csharp
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+    IApplication application = excelEngine.Excel;
+    application.DefaultVersion = ExcelVersion.Xlsx;
+    IWorkbook workbook = application.Workbooks.Create(1);
+    IWorksheet worksheet = workbook.Worksheets[0];
+
+    worksheet.Range["A1"].Text = "Sample Data";
+
+    //Save to memory stream
+    using (MemoryStream stream = new MemoryStream())
+    {
+        workbook.SaveAs(stream);
+
+        //Compute file size in bytes
+        long sizeInBytes = stream.Length;
+        Console.WriteLine($"File size: {sizeInBytes} bytes");
+
+        //Convert to KB 
+        double sizeInKB = sizeInBytes / 1024.0;
+        Console.WriteLine($"File size: {sizeInKB:F2} KB");
+    }
+}
+```
