+# How to apply custom filtering to string data types using XlsIO?
+
+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 apply custom filtering to string data types using XlsIO.
+
+```csharp
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+    IApplication application = excelEngine.Excel;
+    application.DefaultVersion = ExcelVersion.Xlsx;
+    FileStream inputStream = new FileStream(Path.GetFullPath(@"../../../Data/Input.xlsx"), FileMode.Open, FileAccess.Read);
+    IWorkbook workbook = application.Workbooks.Open(inputStream);
+    IWorksheet worksheet = workbook.Worksheets[0];
+
+    //Creating an AutoFilter 
+    worksheet.AutoFilters.FilterRange = worksheet.Range["A1:A11"];
+    IAutoFilter filter = worksheet.AutoFilters[0];
+
+    //Specifying first condition
+    IAutoFilterCondition firstCondition = filter.FirstCondition;
+    firstCondition.ConditionOperator = ExcelFilterCondition.DoesNotContain;
+    firstCondition.String = "1000.00";
+
+    //Saving the workbook
+    FileStream outputStream = new FileStream(Path.GetFullPath("../../../Output/Output.xlsx"), FileMode.Create, FileAccess.Write);
+    workbook.SaveAs(outputStream);
+
+    //Dispose streams
+    outputStream.Dispose();
+    inputStream.Dispose();
+}
+```
