 Filtering allows you to view specific rows in a spreadsheet while hiding the others. The [allowFiltering](https://help.syncfusion.com/cr/aspnetcore-js2/syncfusion.ej2.spreadsheet.spreadsheet.html#Syncfusion_EJ2_Spreadsheet_Spreadsheet_AllowFiltering) property allows you to enable or disable filtering functionality through the UI. You can also use the [allowFiltering](https://help.syncfusion.com/cr/aspnetcore-js2/syncfusion.ej2.spreadsheet.spreadsheet.html#Syncfusion_EJ2_Spreadsheet_Spreadsheet_AllowFiltering) property and `applyFilter` method combination to filter data via code behind. The filtered rows can be identified by iterating through the row collection on the sheet and using the `isFiltered` property available in each row object.

 A sheet is a collection of cells organized in the form of rows and columns that allows you to store, format, and manipulate the data. Using `insertSheet` method, you can insert one or more sheets at the desired index. Then, you can make the inserted sheet as active sheet by focusing the start cell of that sheet using the `goTo` method.
