+# How to assign data to multiple rows and columns in parallel without exceptions in C#?
+
+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 Syncfusion.XlsIO;
+```
+
+Step 5: Include the below code snippet in **Program.cs** to assign data to multiple rows and columns in parallel in C#.
+```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];
+
+    object m_lock = new object();
+    int numberOfRows = 10;
+    Parallel.For(1, numberOfRows, i =>
+    {
+        var rand = new Random();
+        lock (m_lock)
+        {
+            worksheet.Range[i, 1].Value2 = string.Format("R{0}T{1}", i, rand.Next(10));
+            worksheet.Range[i, 2].Value2 = string.Format("R{0}T{1}", i, rand.Next(10));                    
+            worksheet.Range[i, 3].Value2 = DateTime.Now.AddDays(rand.NextDouble() * 10.0);
+            worksheet.Range[i, 4].Value2 = DateTime.Now.AddDays(rand.NextDouble() * 10.0);
+            worksheet.Range[i, 5].Value2 = rand.Next(2000);
+            worksheet.Range[i, 6].Value2 = rand.Next(4000);                   
+            worksheet.Range[i, 7].Value2 = rand.NextDouble() * 10000.0;
+            worksheet.Range[i, 8].Value2 = rand.NextDouble() * 10000.0;
+        }
+    });

+    //Saving the workbook
+    workbook.SaveAs("../../../Output/Output.xlsx");
+    #endregion
