Password Protect Or Unprotect Shared Workbook

Protecting a shared workbook with a password is important to ensure data privacy. With Aspose.Cells for .NET, you can easily protect or unprotect a shared workbook using passwords. Follow the steps below to get the desired results:

Step 1: Specify output directory

First, you need to specify the output directory where the protected Excel file will be saved. Here’s how to do it using Aspose.Cells:

// Output directory
string outputDir = RunExamples.Get_OutputDirectory();

Step 2: Create an empty Excel file

Then you can create an empty Excel file on which you want to apply protection or unprotection. Here is a sample code:

// Create an empty Excel workbook
Workbook wb = new Workbook();

Step 3: Protect or unprotect the shared workbook

After creating the workbook, you can protect or unprotect the shared workbook by specifying the appropriate password. Here’s how:

// Protect the shared workbook with a password
wb.ProtectSharedWorkbook("1234");

// Uncomment this line to unprotect the shared workbook
// wb.UnprotectSharedWorkbook("1234");

Step 4: Save the output Excel file

Once you apply protection or unprotection, you can save the protected Excel file to the specified output directory. Here’s how to do it:

// Save the output Excel file
wb.Save(outputDir + "outputProtectSharedWorkbook.xlsx");
Console.WriteLine("PasswordProtectOrUnprotectSharedWorkbook executed successfully.\r\n");
