5. Disable Protected View in Excel Files using IronXL

IronXL is a top-of-the-line Excel Library, using its advanced features you can easily disable protected view messages using C# code. First, we need an example Excel file that has protected view enabled.

An Excel file with the protection view enabled

You can easily disable the protected view message with the following code example:

using IronXL;

class Program
{
    static void Main(string[] args)
    {
        // Load the Excel workbook with protection view enabled.
        WorkBook workBook = WorkBook.Load("sample1.xlsx");

        // Get the default worksheet from the workbook.
        WorkSheet workSheet = workBook.DefaultWorkSheet;

        // Disable the protection on the worksheet.
        workSheet.UnprotectSheet();

        // Save the modified workbook to a new file.
        workBook.SaveAs("sample2.xlsx");
    }
}

using IronXL;

class Program
{
    static void Main(string[] args)
    {
        // Load the Excel workbook with protection view enabled.
        WorkBook workBook = WorkBook.Load("sample1.xlsx");

        // Get the default worksheet from the workbook.
        WorkSheet workSheet = workBook.DefaultWorkSheet;

        // Disable the protection on the worksheet.
        workSheet.UnprotectSheet();

        // Save the modified workbook to a new file.
        workBook.SaveAs("sample2.xlsx");
    }
}

Imports IronXL

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Load the Excel workbook with protection view enabled.
		Dim workBook As WorkBook = WorkBook.Load("sample1.xlsx")

		' Get the default worksheet from the workbook.
		Dim workSheet As WorkSheet = workBook.DefaultWorkSheet

		' Disable the protection on the worksheet.
		workSheet.UnprotectSheet()

		' Save the modified workbook to a new file.
		workBook.SaveAs("sample2.xlsx")
	End Sub
End Class

Imports IronXL

Friend Class Program
	Shared Sub Main(ByVal args() As String)
		' Load the Excel workbook with protection view enabled.
		Dim workBook As WorkBook = WorkBook.Load("sample1.xlsx")

		' Get the default worksheet from the workbook.
		Dim workSheet As WorkSheet = workBook.DefaultWorkSheet

		' Disable the protection on the worksheet.
		workSheet.UnprotectSheet()

		' Save the modified workbook to a new file.
		workBook.SaveAs("sample2.xlsx")
	End Sub
End Class

In this code, we open an Excel workbook using the WorkBook.Load method and then load the default Excel worksheet using the workBook.DefaultWorkSheet property. Next, workSheet.UnprotectSheet disables the Protected View as required, and finally, workBook.SaveAs is used to save the modifications to a new Excel file.

Here is the output screenshot.

The output Excel file

As you can see, Microsoft Excel's enable editing functions are now available.
