Verify Password Used to Protect the Worksheet with Node.js via C++

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

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

const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "Sample.xlsx");
// Create an instance of Workbook and load a spreadsheet
const workbook = new AsposeCells.Workbook(filePath);

// Access the protected Worksheet
const sheet = workbook.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("1234")) {
        console.log("Specified password has matched");
    } else {
        console.log("Specified password has not matched");
    }
}
