Verify Password Used to Protect the Worksheet

Aspose.Cells APIs have enhanced the Protection class by introducing some useful properties & methods. One such method is the verifyPassword which allows specifying a password as an instance of String and verifies if the same password has been used to protect the Worksheet.

Verify Password Used to Protect the Worksheet

The Protection.verifyPassword method returns true if the specified password matches with the password used to protect the given worksheet, false if the specified password does not match. Following piece of code uses the Protection.verifyPassword method in conjunction with Protection.isProtectedWithPassword property to detect the password protection, and verifies the password.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(VerifyPasswordtoProtectWorksheet.class);
// Create an instance of Workbook and load a spreadsheet
Workbook book = new Workbook(dataDir + "book1.xlsx");

// Access the protected Worksheet
Worksheet sheet = book.getWorksheets().get(0);

// Check if Worksheet is password protected
if (sheet.getProtection().isProtectedWithPassword()) {
	// Verify the password used to protect the Worksheet
	if (sheet.getProtection().verifyPassword("password")) {
		System.out.println("Specified password has matched");
	} else {
		System.out.println("Specified password has not matched");
	}
