Detect if Worksheet is Password Protected with Node.js via C++

It is possible to protect the workbooks and worksheets separately. For instance, a spreadsheet may contain one or more worksheets that are password‑protected; however, the spreadsheet itself may or may not be protected. Aspose.Cells APIs provide the means to detect whether a given worksheet is password protected. This article demonstrates the usage of Aspose.Cells for Node.js via C++ API to achieve the same.

Aspose.Cells for Node.js via C++ exposes the Protection.isProtectedWithPassword() property to detect if a worksheet is password protected. The Boolean property returns true if the worksheet is password‑protected and false otherwise.

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

// 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 book = new AsposeCells.Workbook(filePath);

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

// Check if worksheet is password protected
if (sheet.getProtection().isProtectedWithPassword()) {
    console.log("Worksheet is password protected");
} else {
    console.log("Worksheet is not password protected");
}
