 The following errors have been handled for filtering,
 * *Out of range validation:* When the selected range is not a used range of the active sheet, it is considered as invalid and the out of range alert with the message `Select a cell or range inside the used range and try again` will be displayed. No filter will be performed if the range is invalid.
 
+## Get the filtered rows
+
+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.
+
+The following code example shows how to get the filtered rows.

+
+If you explore your machine to select and upload an excel document using the file uploader, you will receive the uploaded document as a raw file in the `success` event of the file uploader. In this `success` event, you should pass the received raw file as an argument to the Spreadsheet's `open` method to see the appropriate output.

+### To Open Spreadsheet data as a Base64 string
+
+In the Syncfusion Spreadsheet component, there is no direct option to open data as a `Base64` string. To achieve this, the `import()` function fetches the `Base64` string, converts it to a Blob, creates a File object from the Blob, and then opens it using the `open` method in the spreadsheet.

 ### External workbook confirmation dialog
 
 When you open an excel file that contains external workbook references, you will see a confirmation dialog. This dialog allows you to either continue with the file opening or cancel the operation. This confirmation dialog will appear only if you set the `AllowExternalWorkbook` property value to **false** during the open request, as shown below. This prevents the spreadsheet from displaying inconsistent data.

+### To Save Spreadsheet data as a Base64 string
+
+In the Spreadsheet control, there is currently no direct option to save and open data as a `Base64` string. You can achieve this by saving the Spreadsheet data as blob data and then converting that saved blob data to a `Base64` string using `FileReader`.
